 note = {During voluntary movements like walking, the spinal cord regulates functions such as motor and posture control and through inputs from higher cortical areas such as the motor cortex, and from peripheral sources such as the skin and muscle spindles. When cognitive processes are involved during voluntary movements, further input from higher cortical areas may also modulate the spinal cord function. To investigate how changes in the functioning of the higher central nervous system responsible for cognitive functions affect spinal cord function, the amplitude of H-reflexes was induced in the gastrocnemius muscle during a choice reaction time task and
a numerical comparison task. Response times to visual stimuli increased in the order of the choice reaction time task and the numerical comparison task. Furthermore, the amplitude of the H-reflex increased as the response times increased. Our findings suggest that changes in activity of the higher central nervous system such as the parietal association cortex and the prefrontal cortex (which are thought to be active in this task) may modulate the degree of spinal cord disinhibition and, in turn, regulate motor function., Original Article},
