Spatiotemporal cortical activation underlies mental preparation for successful riddle solving: an event-related potential study.

abstract：:The main belly of the macaque's flexor digitorum profundus (FDP) is divided by a dissectible plane into radial and ulnar regions. The present report describes three findings which suggest that the radial and ulnar regions represent separate functional subdivisions of the FDP. First, electromyographic (EMG) recordings ...
