today 's research is differentiating the functions of the precentral and postcentral areas ( 4 , 6pm , 6sma , 3a , 3b , 1 ) : at the microscopic level , by studies of sampled neurons whose discharges can be related to specific components of learnt motor performances , and whose connectivities can be traced by electroanatomical and microscopical labelling of their perikarya , axons and synapses ;
