Recording site. (Upper) Medial view of a monkey's brain. The area enclosed by the dashed line indicates the recording area. The recording site was reconstructed on magnetic resonance images of each monkey. (Lower) Recording sites of navigation (red, green, and black circles) and movement-selective (blue circles) neurons in monkeys nos. 1 (Left) and 2 (Right). Red and green circles indicate the recording sites of route- and location-selective navigation neurons, respectively. The data obtained from both hemispheres are superimposed on those obtained from the right hemisphere. cgs, cingulate sulcus; pos, parietooccipital sulcus; cc, corpus callosum; and cals, calcarine sulcus.
