TITLE:

NEURAL CORRELATES OF MOTOR LEARNING IN HEALTHY YOUNG ADULT MEN

KEY WORDS:

motor learning, EEG, finger tapping, motor imagery, aclon observalon.

PAGES: 47
BIG AREA: Ciências Biológicas
AREA: Fisiologia
SUMMARY:

Evidence in the literature indicates that biological sex significantly impacts the impairment and progression of motor neurological disorders, such as Parkinson's Disease and Amyotrophic Lateral Sclerosis. To achieve a global understanding of how sex interferes with motor learning, it is essenlal to establish baseline neurophysiological parameters for each sex. Within this context, this work consists of an inilal study focused on mapping motor learning processes in healthy male individuals. Twenty young adult males underwent three experimental sessions with electroencephalographic (EEG) recording during motor imagery, aclon observalon, and finger tapping protocols. The analysis of these protocols elucidated how motor learning occurs under different demands. In motor imagery, an evolulon in execulon capacity was observed across sessions, associated with increased aclvalon of temporoparietal regions. In aclon observalon, both global and focal corlcal changes (centro-parietal regions) were verified, indicalng mechanisms linked to energy efficiency through the recruitment of more specific neural circuits. In finger tapping, the focal effect of the beta rhythm and the crilcal role of the mu rhythm in coordinalng movement-related circuits were highlighted. It is concluded that this study establishes important neural signatures of male motor learning, serving as a fundamental starlng point for future comparalve inveslgalons involving female individuals.
