Abstract

Members of a Roma (Gypsy) family with hereditary motor and sensory peripheral neuropathy (HMSN) and concomitant auditory and vestibular cranial neuropathies were identified in Kocevje, Slovenia. The illness begins in childhood with a severe and progressive motor disability and the deafness is delayed until the second decade. There are no symptoms of vestibular dysfunction. The family structure is consistent with an autosomal recessive pattern of inheritance and the genetic locus for the disorder is linked to the same region of chromosome 8q24 as other Roma families with HMSN and deafness from Lom, Bulgaria (HMSN-Lom). The present study shows that the deafness is caused by a neuropathy of the auditory nerve with preserved measures of cochlear outer hair cell function (otoacoustic emissions and cochlear microphonics) but absent neural components of auditory brainstem potentials. The hearing loss affects speech comprehension out of proportion to the pure tone loss. Vestibular testing showed absence of caloric responses. Physiological and neuropathological studies of peripheral nerves were compatible with the nerve disorder contemporaneously affecting Schwann cells and axons resulting in both slowed nerve conduction and axonal loss. Genetic linkage studies suggest a refinement of the 8q24 critical region containing the HMSN-Lom locus that affects peripheral motor and sensory nerves as well as the cranial auditory and vestibular nerves.

Abstract

Background Acute myopathy or neuropathy is a common complication in critically ill patients in intensive care unit. This complication is relatively obvious in patients with primary non-neurological disorder. However, such complication is difficult to notice in patients with primary neurological disorder. The aim of our report is to present four patients with a primary central nervous disease who subsequently developed a secondary peripheral nervous disorder. Patients and The four patients had been admitted to the intensive care unit of the Neurological Demethods partment for the acute cerebral disorder. Additionally in the course of disease they had developed clinical signs of either neuropathy or myopathy. One patient was unable to wean from the ventilator. Electrodiagnostic studies and muscle biopsy were performed. Results Electrodiagnostic studies revealed generalized abnormalities, consistent with both neuropathy and myopathy. The predominant finding in muscle biopsy was a myopathy with moderate to severe myosin filament loss. Conclusions This report brings two messages. The first is that one should be aware of the possibility of critical illness myopathy/neuropathy also in the neurological intensive care unit. As this peripheral neurological complication is superimposed on primary central neurological disorder, it may be more difficult to notice and to diagnose it clinically. The second message is that electrodiagnostic studies, though mandatory in confirming peripheral lesion, often cannot distinguish between myopathy and neuropathy. As myopathy bears substantially favorable prognosis, a muscle biopsy may be recommended in such cases.

49. Using ANN on EEG signals to predict working memory task response.

Abstract

Many authors have shown that performing working-memory tasks causes an elevated neuronal activity in several areas of the human brain, which suggests information exchange between them. Since the information exchanged, encoded in brain waves is measurable by electroencephalography (EEG) it is reasonable to assume that it can be extracted with an appropriate method. In this paper we present a method for extracting the information using an artificial neural network (ANN), which we consider as a stimulusresponse model. The EEG was recorded from three subjects while they performed a modified Sternberg task that required them to respond to each trial with the answer "true" or "false". The study revealed that a stimulus-response model can successfully be identified by observing phase-demodulated theta-band EEG signals 1 second prior to a subject's answer. The results showed that the model was able to predict the answers from the EEG signals with an average reliability of 75% for all three subjects. From this we concluded that stimulus-response model successfully observes the system states and consequently predicts the correct answer using the EEG signals as inputs. [ABSTRACT FROM AUTHOR]

50. Identification of Gripping-Force Control from Electroencephalographic Signals.

Abstract

The exact mechanism of information transfer between different brain regions is still not known. The theory of binding tries to explain how different aspects of perception or motor action combine in the brain to form a unitary experience. The theory presumes that there is no specific center in the brain that would gather the information from all the other brain centers, governing senses, motion, etc., and then make the decision about the action. Instead, the centers bind together when necessary, maybe through electromagnetic (EM) waves of specific frequency. Therefore, it is reasonable to assume that the information that is transferred between the brain centers is somehow coded in the electroencephalographic (EEG) signals. The aim of this study was to explore whether it is possible to extract the information on brain activity from the EEG signals during visuomotor tracking task. In order to achieve the goal, artificial neural network (ANN) was used. The ANN was used to predict the measured gripping-force from the EEG signal measurements and thus to show the correlation between EEG signals and motor activity. The ANN was first trained with raw EEG signals of all the measured electrodes as inputs and gripping-force as the output. However, the ANN could not be trained to perform the task successfully. If we presume that brain centers transmit and receive information through EM signals, as suggested by the binding theory, a simplified model of signal transmission in brain can be proposed. We propose a computational model of a human brain where the information between centers is transmitted as phase-modulation of certain carrier frequency. Demodulated signals were then used as the inputs for the ANN and the gripping-force signal was used as the output. It was possible to train the network to efficiently calculate the gripping-force signal from the phase-demodulated EEG signals. [ABSTRACT FROM AUTHOR]
