The integrity of the cerebral cortex can be assessed by measuring its responsiveness to repetitive sensory stimulation and voluntary motor activity. This neurophysiologic feature is called neural adaptation, and is thought to enhance learning and detection of environmental stimuli. The adaptation of hemodynamic responses to motor and sensory experiences in hand and face are of particular interest—as these are structures used in human communication—and proper delivery of oxy-hemoglobin to primary motor (M1) and somatosensory (S1) cortices is essential for functional cortical activation.
The objective of this study was to examine the hemodynamic differences between hand and face cortical representations during …
