Moving a hand is like sailing: your motor cortex, the captain, receives hand location information to define movement parameters; and throughout the movement, your somatosensory areas, the localization equipment, gather data to ensure your hand is on the correct course, and to guide the captain in further commands. Models of information flow in primates suggest that during volitional movement, the sensory state information in Brodmann Area 3b (Ba3b) is spread to Ba4, then sent to muscles via motor commands, followed by muscle proprioceptive information through the thalamus to Ba2, and finally b
