Fig. 9.

Example PPC neuron in the no hand vision and concurrent hand vision tasks. This neuron was recorded at a depth of 2.75 mm, close to the juncture of superficial and deep cortex. Color maps and vector fields for the right and left workspaces (top and middle, respectively) and 2 visual conditions in the same workspace (middle and bottom, respectively) are shown. Other figure conventions are as described in Figs. 4 and 5.
