Abstract

Nine healthy righthanded volunteers were scanned 1 while performing bilateral finger movements nondiscrimination motor task and 2 while performing a bimanual tactile–tactile matching discrimination task using small chess pieces tactile discrimination taskExtensive activations were specifically observed in the parietal SII superior lateral lobule insular prefrontal cingulate and neocerebellar cortices HVIII with a left predominance in motor areas during the tactile discrimination task in contrast to the findings during the nondiscrimination motor taskBimanual tactile–tactile matching discrimination recruits multiple sensorimotor and associative cerebral and neocerebellar networks including the cerebellar second homunculus HVIII comparable to the neural circuits involved in unimanual tactile object recognition
