Selectivity for grip type and action goal in macaque inferior parietal and ventral premotor grasping neurons

摘要

in both humans and monkeys, the visuo-motor transformations of objects' physical properties into specific types of grip occur in a cortical circuit formed by the anterior intraparietal area (AIP) and the ventral premotor cortex (PMv) (Davare et al. 2011; Grafton 2010; Rizzolatti and Luppino 2001).Single-neuron recording studies in monkeys demonstrated that AIP (Baumann et al. 2009; Murata et al. 1996, 2000; Sakata et al. 1995, 1997; Taira et al. 1990) and the ventral premotor area F5 (Fluet et al. 2010; Murata et al. 1997; Raos et al. 2006) play crucial roles in the visuo-motor transformations necessary for grasping objects.
