Cognitive skills are a set of higher-order thinking processes that allow children to learn successfully. By developing cognitive skills, the brain is connected to Rapidly complete the information processes. The aim of this study was to examine the cognitive process development, decision making and eventually cognitive performance in school-age children evaluated by the galvanic skin conductance response (SCR) method. Peripheral SCR signals during cognitive loading were recorded in children in grades 1 to 3 of a representative school in Southern Thailand. Eriksen flanker and dexterity tests were conducted to evaluate the development of its association with cognitive skill. Regression-based analyses showed reduced reaction time on Eriksen flanker (both congruent trials with regression coefficient = -0.02924, p <0.001 and incongruent trials with regression coefficient = -0.04231, p <0.001) and time spent to achieve dexterity tests (regression coefficient = -0.32206379, p <0.05) from students' grades 1 to 3. In SCR modulation, analysis of variance revealed highest peak SCR magnitudes in students grade 3, compared to students in grade 2 (p <0.001) and grade 1 (p =0.046). On the other hands, numbers of peaks were highest in students grade 1 when they were in the calm stage (p <0.001), and highest in student grade 3 (p =0.002) when they were in the focus mind state. These findings support the association of the psychophysiological index of changes in brain and cognitive development among age related experience to focus attention improving under the task.

Background/Aim: There seems to be a correlation between changes in movement patterns with aging and brain activation. In the preparation and execution of movements, neural oscillations play an important role. In this study, cortical high frequency brain oscillations were analyzed in 15 healthy young adults and 15 elderly adults who participated in eyehand coordination tasks. Patients and Methods: The brain activities of healthy young and older adults were recorded using electroencephalography (EEG). Results: Elderly participants spent significantly more time completing the task than young participants. During eye-hand coordination in elderly groups, beta power decreased significantly in the central midline and parietal brain regions. The data suggest that healthy elderly subjects had intact cognitive performance, but relatively poor eye-hand coordination associated with loss of beta brain oscillation in the central midline and parietal cortex and reduced ability to attentional movement. Conclusion: Beta frequency in the parietal brain sites may contribute to attentional movement. This could be an important method for monitoring cognitive brain function changes as the brain ages.

Background/Aim: The same neural processes may govern older people's motor and cognitive abilities since an inability to switch between actions develops with aging. In this study, a dexterity test was used to measure motor and cognitive perseverance, which required participants to move their fingers fast and correctly on hole boards. Materials and Methods: An electroencephalography (EEG) recording was used to evaluate how healthy young and older adults process brain signals when performing the test. Results: A significant difference was found between the young and older groups in the average time taken to complete the test, with the older group taking 87.4 s and the young group taking 55.21 s. During motor movement, young participants showed alpha desynchronization over the cortex (Fz, Cz, Oz, Pz, T5, T6, P3, P4) in comparison to the resting state. However, compared to the younger group, no alpha desynchronization was found in the aging group during motor performance. It was noteworthy that alpha power (Pz, P3, and P4) in the parietal cortex was significantly lower in older compared to young adults. Conclusion: Age-related slowdown in motor performance may be caused by deteriorating alpha activity in the parietal cortex, which functions as a sensorimotor interface. This study provides new insights into how perception and action are distributed between brain regions. [ABSTRACT FROM AUTHOR]

Background/Aim: The dorsal striatum is a brain area integrating information for movement output. The local field potentials (LFPs) reflect the neuronal activity that can be used for monitoring brain activities and controlling movement. Materials and Methods: Rhythmic low gamma power activity (30.1-45 Hz) in the dorsal striatum was monitored according to voluntary motor movement in rotarod and bar tests in 0.5 mg/kg haloperidol-induced mice. Results: Haloperidol can effectively induce movement impairment indicated by decreased low gamma LFP with the lessened rotarod test's latency fall, and the enhanced bar test's descending latency. L-DOPA was used for the induction of a dopamine-dependent signal. The results showed that 25 mg/kg of L-DOPA could reverse the effect of haloperidol by enhancing low gamma oscillation concomitantly with the improvement in behavioral movement as fast as 60 min after administration, suggesting that dopamine signaling increases low gamma frequency of LFP in correlation with the improved mice movement. This work supports quantitative LFP assessment as a monitoring tool to track drug action on the nervous system. Conclusion: In animal models of motor impairment, oral dopaminergic treatment can be effective in restoring motor dysfunction by stimulating low gamma power activity in the dorsal striatum.
