7. Olfactory Fear Conditioning Induces Field Potential Potentiation in Rat Olfactory Cortex and Amygdala

Author

Messaoudi, Belkacem, Granjon, Lionel, and Mouly, Anne-Marie

Abstract

The widely used Pavlovian fear-conditioning paradigms used for studying the neurobiology of learning and memory have mainly used auditory cues as conditioned stimuli (CS). The present work assessed the neural network involved in olfactory fear conditioning, using olfactory bulb stimulation-induced field potential signal (EFP) as a marker of plasticity in the olfactory pathway. Training consisted of a single training session including six pairings of an odor CS with a mild foot-shock unconditioned stimulus (US). Twenty-four hours later, the animals were tested for retention of the CS as assessed by the amount of freezing exhibited in the presence of the learned odor. Behavioral data showed that trained animals exhibited a significantly higher level of freezing in response to the CS than control animals. In the same animals, EFPs were recorded in parallel in the anterior piriform cortex (aPC), posterior piriform cortex (pPC), cortical nucleus of the amygdala (CoA), and basolateral nucleus of the amygdala (BLA) following electrical stimulation of the olfactory bulb. Specifically, EFPs recorded before (baseline) and after (during the retention test) training revealed that trained animals exhibited a lasting increase (present before and during presentation of the CS) in EFP amplitude in CoA, which is the first amygdaloid target of olfactory information. In addition, a transient increase was observed in pPC and BLA during presentation of the CS. These data indicate that the olfactory and auditory fear-conditioning neural networks have both similarities and differences, and suggest that the fear-related behaviors in each sensory system may have at least some distinct characteristics.

Abstract

Human newborns can propel themselves to their mother's breast when positioned skin to skin on her abdomen just after birth. For decades, researchers have considered this primitive crawling behavior a spinal reflex, immune to supra spinal control. However, recent research suggests that neonatal crawling is already responsive to visual and olfactory stimuli processed at a supra spinal level. Here we report that a few hours post birth, French newborns can also modulate their crawling in response to their native language – a source of information that is processed supra‐spinally. The crawling patterns of 23 French‐born newborns were recorded on video and via an infrared motion capture system during two randomly ordered 2‐min trials. The newborns were secured on a mini skateboard to facilitate arm and leg movements during their crawling propulsion. They heard a repetitive sequence of the same sentences either in French, their native language, or in English, a rhythmically different and hence discriminable unfamiliar language, on each trial. In French, compared to English, crawling was enhanced, with significantly more arm and leg steps and significantly more and larger trunk rotations in the cephalo‐caudal axis. Moreover, newborns rotated their heads and trunk toward the appropriate loud speaker when hearing French but not English. These preliminary findings suggest that newborn crawling is not a simple stereotyped reflex under spinal control, but a complex pattern that can be modulated in response to higher‐order, supra‐spinally processed stimuli. The findings open fascinating questions about the range of stimuli to which newborn crawling is responsive. [ABSTRACT FROM AUTHOR]

Abstract

The crawling behavior of sixty 2-day-old newborns was studied while they were supported prone on a mini skateboard and on a pediatric mattress without additional support. Analyses of the number and types of limb movements and their characteristics, the coactivation of limb pairs, and the displacement across the surface, revealed that newborns can crawl with locomotor patterns similar to those documented during quadrupedal locomotion in animals and human adults. This was particularly apparent on the skateboard. This discovery suggests that locomotor circuitry underlying quadrupedal locomotion develops during fetal life. Drawing upon other evidence for a quadrupedal organization underlying bipedal gait, we argue that early quadrupedal training may enhance interventions designed to hasten the onset of independent walking.

Abstract

Autism spectrum disorder (ASD) is characterized by difficulties in the social domain, but also by hyper‐ and hypo‐reactivity. Atypical visual behaviours and processing have often been observed. Nevertheless, several similar signs are also identified in other clinical conditions including cerebral visual impairments (CVI). In the present study, we investigated emotional face categorization in groups of children with ASD and CVI by comparing each group to typically developing individuals (TD) in two tasks. Stimuli were either non‐filtered or filtered by low‐ and high‐spatial frequencies (LSF and HSF). All participants completed the autism spectrum quotient score (AQ) and a complete neurovisual evaluation. The results show that while both clinical groups presented difficulties in the emotional face recognition tasks and atypical processing of filtered stimuli, they did not differ from one another. Additionally, autistic traits were observed in the CVI group and symmetrically, some visual disturbances were present in the ASD group as measured via the AQ score and a neurovisual evaluation, respectively. The present study suggests the relevance of comparing ASD to CVI by showing that emotional face categorization difficulties should not be solely considered as autism‐specific but merit investigation for potential dysfunction of the visual processing neural network. These results are of interest in both clinical and research perspectives, indicating that systematic visual examination is warranted for individuals with ASD. [ABSTRACT FROM AUTHOR]

Abstract

A growing literature shows that perception and action are already tightly coupled in the newborn. The current study aimed to examine the nature of the coupling between olfactory stimuli from the mother and the newborn's crawling and rooting (exploratory movements of the head). To examine the coupling, the crawling and rooting behavior of 28 2‐day‐old newborns were studied while they were supported prone on a mobility device shaped like a mini skateboard, the Crawliskate®, their head positioned directly on top of a pad infused with either their mother's breast odor (Maternal) or the odor of water (Control). Video and 3D kinematic analyses of the number and types of limb movements and quantification of displacement across the surface revealed that newborns are significantly more efficient crawlers when they smell the maternal odor, moving greater distances although performing fewer locomotor movements. In addition, the newborns made significantly more head rooting movements in the presence of the maternal odor. These findings suggest that the circuitry underlying quadrupedal locomotion and exploratory movements of the head is already adaptable to olfactory information via higher brain processing. Moreover, the coupling between olfaction and the two action systems, locomotion and rooting, is already differentiated. As crawling enables the newborn to move toward the mother's breast immediately after birth and facilitates mother–infant interaction, the results of this study highlight the potential value of using maternal odors to stimulate mobility in infants at risk of motor delay and/or deprived of this odor when born prematurely.

Abstract

The present study examines the effect of language experience on vocal emotion perception in a second language. Native speakers of French with varying levels of self-reported English ability were asked to identify emotions from vocal expressions produced by American actors in a forced-choice task, and to rate their pleasantness, power, alertness and intensity on continuous scales. Stimuli included emotionally expressive English speech (emotional prosody) and non-linguistic vocalizations (affect bursts), and a baseline condition with Swiss-French pseudo-speech. Results revealed effects of English ability on the recognition of emotions in English speech but not in non-linguistic vocalizations. Specifically, higher English ability was associated with less accurate identification of positive emotions, but not with the interpretation of negative emotions. Moreover, higher English ability was associated with lower ratings of pleasantness and power, again only for emotional prosody. This suggests that second language skills may sometimes interfere with emotion recognition from speech prosody, particularly for positive emotions., Postprints der Universität Potsdam : Humanwissenschaftliche Reihe, 503

28. Effects of Word Position on the Acoustic Realization of Vietnamese Final Consonants.

Author

Tran, Thi Thuy Hien, Vallée, Nathalie, and Granjon, Lionel

Abstract

A var iety of studies have shown differences between phonetic features of consonants according to their prosodic and/or syllable (onset vs. coda) positions. However, differences are not always found, and interactions between the various factors involved are complex and not well understood. Our study compares acoustical characteristics of coda consonants in Vietnamese taking into account their position within words. Traditionally described as monosyllabic, Vietnamese is partially polysyllabic at the lexical level. In this language, tautosyllabic consonant sequences are prohibited, and adjacent consonants are only found at syllable boundaries either within polysyllabic words (CVC.CVC) or across monosyllabic words (CVC#CVC). This study is designed to examine whether or not syllable boundary types (interword vs. intraword) have an effect on the acoustic realization of codas. The results show significant acoustic differences in consonant realizations according to syllable boundary type, suggesting different coarticulation patterns between nuclei and codas. In addition, as Vietnamese voiceless stops are generally unreleased in coda position, with no burst to carry consonantal information, our results show that a vowel's second half contains acoustic cues which are available to aid in the discrimination of place of articulation of the vowel's following consonant.

Abstract

This study focuses on how the body schema develops during the first months of life, by investigating infants’ motor responses to localized vibrotactile stimulation on their limbs. Vibrotactile stimulation was provided by small buzzers that were attached to the infants’ four limbs one at a time. Four age groups were compared cross‐sectionally (3‐, 4‐, 5‐, and 6‐month‐olds). We show that before they actually reach for the buzzer, which, according to previous studies, occurs around 7–8 months of age, infants demonstrate emerging knowledge about their body's configuration by producing specific movement patterns associated with the stimulated body area. At 3 months, infants responded with an increase in general activity when the buzzer was placed on the body, independently of the vibrator's location. Differentiated topographical awareness of the body seemed to appear around 5 months, with specific responses resulting from stimulation of the hands emerging first, followed by the differentiation of movement patterns associated with the stimulation of the feet. Qualitative analyses revealed specific movement types reliably associated with each stimulated location by 6 months of age, possibly preparing infants’ ability to actually reach for the vibrating target. We discuss this result in relation to newborns’ ability to learn specific movement patterns through intersensory contingency. Statement of contribution what is already known on infants’ sensorimotor knowledge about their own bodies 3‐month‐olds readily learn to produce specific limb movements to obtain a desired effect (movement of a mobile). infants detect temporal and spatial correspondences between events involving their own body and visual events. what the present study adds until 4–5 months of age, infants mostly produce general motor responses to localized touch. this is because in the present study, infants could not rely on immediate contingent feedback. we propose a cephalocaudal developmental trend of topographic differentiation of body areas.

Abstract

International audience; Imitation is one of the major processes by which humans develop social interactions. In speech communication, imitative processes are used from birth to adulthood, as highlighted by children’s mimicking abilities and by adult’s tendency to automatically “imitate” a number of acoustic-phonetic characteristics in another speaker’s speech. These adaptive changes are thought to play a key role in speech development/acquisition and to facilitate conversational exchange by contributing to setting a common perceptuo-motor link between speakers. Based on acoustic analyses of speech production in various laboratory tasks, the present study aimed to better characterize sensory-to-motor adaptive processes involved in unintentional as well as voluntary speech imitation, and to test possible motor plastic changes due to auditory-motor recalibration mechanisms.

Abstract

International audience; Auditory verbal hallucinations (AVHs) are a stressful symptom of schizophrenia, affecting 50% to 80% of the patients. AVHs are defined as speech perceptions in the absence of an external auditory stimulus. Some theories explain AVHs as a distortion in the production of inner speech (IS) in a way that the verbal thoughts of the patient are perceived as external voices. These theories can be implemented in the context of a speech motor control model in which the sense of agency derives from the comparison between the predicted and the actual outputs. According to these theories, during IS production in schizophrenia, deficits could arise in the prediction system, disrupting the feeling of agency and leading to hallucinations. The aim of this study was to examine orofacial activity during inner speech in healthy control subjects and during the occurrence of AVHs in schizophrenia patients. 11 French schizophrenia patients and 12 French healthy controls subjects participated in the study. Surface electromyography recordings were obtained in several conditions from 2 orofacial speech muscles: orbicularis oris superior (OOS) and orbicularis oris inferior (OOI) as well as from the nondominant forearm flexor (FF) muscle. The increase in OOI activation from rest to the AVH condition in schizophrenia patients suggests that there could be a speech related muscular activity during AVHs. Our results support the theories according to which AVHs are the consequence of a misattributed IS production: there would be a correct IS production (revealed by muscular activity increase) and a conflict would then take place in the prediction system.

Abstract

National audience; Auditory verbal hallucinations (AVHs) are speech perceptions in the absence of pertinent external stimuli. Some theories explain AVHs as a distortion in the production of inner speech in a way that the verbal thoughts of the patient are perceived as external voices. These theories can be implemented in the context of a speech motor control model. In order to examine the motor aspect of these models, the present study aimed at collecting orofacial muscle activity traces during AVHs. Surface electromyography (sEMG) was used on schizophrenia patients and control subjects. Our results show an increase in muscular activity in the orbicularis oris muscles during AVHs for patients and a trend towards an increase during inner speech for controls, compared to rest.

Abstract

National audience; This article reports a study on the perceptual identification of language and culture, the level of certainty in this choice, and at the same time, the degree of extroversion perceived by 45 French and 45 Italian judges. Judgments are made on non-lexical audible and visible micro-events (e.g. mouth noises, grunts, bursts, interjections and fillers) of 6 French subjects, placed in human-computer interac-tion. These events were ordered and displayed on a 24 stimuli axis by their increasing control of prosody (from an absence of this control) and by their distance from phonological sounds. There were 3 modalities of the test: audio only (A), video only (V) and audio-visual (AV). For each modality 15 judges of each nationality were in-terviewed. The results show that judges from both nation-alities clearly identify the subjects as French. However, while the judgement V modality is mainly based on the subject's appearance (invariable selection of judges from the beginning of the experiment), in the A and AV modal-ities the emergence of prosodic control corresponds to "point of stability" in the culture and language identifica-tion and in the level of certainty in this choice

Abstract

8 pages; National audience; Cet article présente une étude sur l'identification perceptive, par des juges français et italiens, de la langue/culture, le degré de confiance accordé à ce choix, et, en parallèle, du degré d'extraversion. Les jugements sont faits sur des micro-événements acoustiques et visuels non langagiers (ex. bruits de bouche, grunts, bursts, fillers et interjections) de 6 sujets français, placés en interaction personne-machine. Ces événements ont été choisis et ordonnés en listes de 24 stimuli selon un contrôle croissant de la prosodie (à partir d'un non contrôle) et de leur distance des sons phonologiques. Pour chaque modalité de passation (Audio seul ou Visuel seul ou Audio-Visuel), des groupes différents de 15 juges, de chaque nationalité, ont été interrogés. Les résultats montrent une tendance, des juges des deux nationalités, à identifier les sujets comme français. Toutefois, alors qu'en Visuel seul le jugement est surtout fondé sur l'aspect des sujets (choix des juges invariable dès le début de l'expérimentation), en Audio seul et en Audio-Visuel l'apparition du contrôle prosodique correspond à un « point de stabilité » dans le choix langue/culture.

Abstract

International audience; Unintentional imitation is one of the major processes by which humans smooth social interactions. Such convergent behaviors also occur during speech communication, as highlighted by our tendency to automatically 'imitate' a number of phonetic characteristics in another speaker's speech. This phonetic convergence effect is thought to facilitate conversational exchange by contributing to setting a common phonetic ground between speakers, and it provides evidence for perceptuo-motor adaptive processes during speech communication. Based on f0 and F1 acoustic analyses of speech production in various laboratory tasks, the present study aimed to better characterize sensory-to-motor adaptive processes involved in unintentional as well as voluntary speech imitation, and to test possible motor plastic changes due to global auditory-motor remapping. To this aim, three groups of participants involved in speech production or imitation tasks were exposed via loudspeakers to vowel utterances spoken by different speakers. The first task was designed to induce unintentional imitation of acoustically presented vowels and to measure the magnitude of imitative changes in speech production as well as possible motor after-effects. Participants were instructed to produce vowels according to either an orthographic or an acoustic cue, without any instructions to repeat or to imitate the acoustic cues. A block design was used where participants produced the vowel target according first to an orthographic cue (baseline), then to an acoustic cue (phonetic convergence) and finally to an orthographic cue (motor after-effect). To compare phonetic convergence and voluntary imitation of the acoustic vowels, we asked the second group of participants to imitate the acoustically presented vowels. In a third task, we tested whether motor after-effects can also occur without prior unintentional or voluntary vowel imitation but only after auditory exposure of the acoustic targets. The three tasks were performed in a soundproof room using the same experimental setting and participants' productions were recorded for offline analyses. A semi-automatic analysis of the recorded vowels (around 14'000 utterances) was performed on f0 and F1 acoustic parameters. In the first task, analyses of covariance demonstrate that producing a vowel according to an acoustic cue led to a small but significant unintentional imitation of f0 and F1 (all p's < .001) and to short-term motor plastic changes in the subsequent productions based on orthographic cues (f0: p < .008; f1: p < .01). As expected, similar results were observed in the second imitation task with a much greater magnitude of imitative and after-effect changes (all p's < .001). Finally, simple auditory exposure to vowels in the third task led to similar after-effects as observed in the first task (f0: p < .001; F1: p < .02). These results demonstrate automatic imitative processes during speech communication even at a fine-grained acoustic-phonetic level and highlight the role of ambient speech in adjusting phonemic auditory-motor goals. They provide evidence for both mirror mechanisms and feedback control mechanisms as suggested by recent neurophysiological and behavioral studies on speech perception and production.

Abstract

By the end of their first year of life, infants' representations of familiar words contain phonetic detail; yet little is known about the nature of these representations at the very beginning of word learning. Bouchon et al. () showed that French-learning 5-month-olds could detect a vowel change in their own name and not a consonant change, but also that infants reacted to the acoustic distance between vowels. Here, we tested British English-learning 5-month-olds in a similar study to examine whether the acoustic/phonological characteristics of the native language shape the nature of the acoustic/phonetic cues that infants pay attention to. In the first experiment, British English-learning infants failed to recognize their own name compared to a mispronunciation of initial consonant (e.g., Molly versus Nolly) or vowel (e.g., April versus Ipril). Yet in the second experiment, they did so when the contrasted name was phonetically dissimilar (e.g., Sophie versus Amber). Differences in phoneme category (stops versus continuants) between the correct consonant versus the incorrect one significantly predicted infants' own name recognition in the first experiment. Altogether, these data suggest that infants might enter into a phonetic mode of processing through different paths depending on the acoustic characteristics of their native language.

Abstract

As soon as infants grasp objects, they exhibit some degree of hand preference. Although all studies agree that the number of non-lateralized infants remains high during the first months of life, there is no consensus on the percentage of right- and left-handed infants. Reasons might be the different formulae used to calculate an handedness index, the basis on which handedness categories are distinguished, and the number of trials per session. In this study we aimed to provide a valid method of testing handedness, reliable without being lengthy so as to combine it with other evaluations. We tested 46 infants at 9 and 11 months by giving them 34 trials. We compared the results using 2 of the most used formulae, including the bimanual grasps or not, and considering the first 5, 10, 15, 20, 26, 31, or all 34 trials. The results show that different formulae do not give significantly different results as long as bimanual grasps are included. The number of trials is important: 15 trials are necessary for the reliability of the classification into handedness categories. Giving more trials does not provide substantial additional information. [ABSTRACT FROM AUTHOR]
