Abstract:
Taga et al. (J Neurophysiol 132: 1917-1936, 2024) investigates the distinct roles of the corticospinal tract (CST) and corticoreticulospinal tract (CReST) in chronic motor behaviors post stroke. Their findings indicate that CST projection strength is associated with motor control and muscle individuation, whereas CReST projection strength is associated with strength. These results provide evidence that the CST and CReST pathways serve unique but complementary functions in regulating human movement.
