Abstract:
:A commissurotomy patient and two neurologically intact control observers were required to encode spatial patterns presented concurrently to the two hemifields. Under conditions of maximal perceptual load, in which different patterns appeared in the two fields, the commissurotomy patient encoded more information than the control observers. Based on these findings, it is concluded that competition for common internal processing mechanisms interferes with overall processing efficiency.

NEUROPSYCHOLOGIA文献大全abstract::The neurobiology of handedness is still poorly understood in nonhuman primates. Recently, an association between hand preference and precentral gyrus morphology in chimpanzees was reported. The aim of this study was to further evaluate the association between handedness and asymmetries in the precentral gyrus of chimp...
