Differential control of the digits of the human hand: evidence from digital anaesthesia and weight matching.

abstract：:A database of positron-emission-tomography studies published between January 1993 and November 1996 was created to address several questions regarding the function and connectivity of the human anterior cingulate cortex (ACC). Using this database, we have previously reported on the relationship between behavioural var...
