Forelimb movement representations following skilled reach training. a, Representative forelimb movement representation topography derived in a reach-trained rat. b, Reach-trained rats did not demonstrate any specific increase in individual movement representation size relative to naive controls. c, Although forelimb representation sizes between groups were equivalent, there was a significant (p = 0.0001) increase in the proportion of forelimb movement representations that also elicited nonforelimb movements following training. d, Post hoc analyses revealed that jaw (p = 0.0022) and neck (p = 0.0001) movements overlapping within the forelimb movement representations in reach-trained rats were significantly increased. *p < 0.05.
