title: Differences in direction specificity of receptive fields in upper and lower layers of the cat's prestriate area 18.
abstract: Direction specificity was measured for neurons in area 18 (A18) in penetrations approximately perpendicular to the layers in awake cats. A majority of lower layer cells (below 1.0 mm) preferred stimuli moving at rather orthogonal directions with respect to the preferred directions of the neurons in the upper layers (0-1.0 mm). The results suggest more functional autonomy of the corresponding cortical layers.
