title: Pyramidal cell specialization in the occipitotemporal cortex of the vervet monkey.
abstract: Pyramidal cells were injected intracellularly in fixed, flat-mounted cortical slices taken from the first and fourth visual areas (V1 and V4, respectively) and cytoarchitectonic areas TEO and TE of two age and gender-matched vervet monkeys and the size, branching complexity and spine density of their basal dendritic trees determined. In both animals, we found marked differences in the pyramidal cell phenotype between cortical areas. More specifically, a consistent trend for larger, more branched and more spinous pyramidal cells with progression through V1, V4, TEO and TE was observed. These findings support earlier reports of interareal specialization in pyramidal cell structure in occipitotemporal visual areas in the macaque monkey.
