Response profiles of three neurons in the top (fourth) layer of VisNet before training.

<p>Each of the three columns shows the firing responses of a particular cell. Each row shows the responses of the cells to one of the three hand-object configurations over all five retinal locations shown along the abscissae. Top row: visual object is shown in the ‘Up’ location with respect to the hand. Middle row: visual object is shown in the ‘Left’ location with respect to the hand. Bottom row: visual object is shown in the ‘Right’ location with respect to the hand. It can be seen that each of the three cells initially responds randomly to each of the hand-object configurations over the different retinal locations.
