Figure 2

Immunohistochemical assessment of electrode tracks, areas and layers. A. Dorsal surface with the recording trenches (boxes) shown overlying the left hemisphere where simultaneous recordings were made from each region as shown in Figure 4. The 5 asterisks on the right hemisphere locate where the photographs of normal cortex were taken below (C., D., E.). The level as “E” is that for the electrode tracks shown in B. The splenium of the corpus callosum is at level “S” and the splenial sulcus (spls) is shown with two asterisks in the left hemisphere. “G” and “B” levels refer to the genu of the corpus callosum and bregma, respectively. B. Electrode tracks shown in layer Va of area 32. The red asterisk is at the border between layers IV and Va in this section, between layers III and Va in other ACC and MCC areas, and between layers IV and Va in area 30 (E.). All calibration bars are 500 μm.
