- Fig. 1.
Five sections from each animal to illustrate the unilateral perirhinal cortex lesion. The entire hemisphere is shown in the top row, for orientation, and the temporal lobe is shown at greater magnification in the four lower rows. The sections, running from anterior at the left to posterior at the right, are from S3 (rows 1 and 2), S1 (row 3), S2 (row 4), and S4 (row 5). Sections are ∼2.5 mm apart in the fixed tissue. See text for description of ablations. Sections from animals S1, S2, and S3 are from the right hemisphere. The sections from animal S4 are from the left hemisphere and have been mirror-image-reversed for ease of comparison with the other animals.
- Fig. 2.
Three sections from one animal (S3) to illustrate the method of unilateral fornix transection. The sections are 1.5 mm apart in the fixed tissue and run from anterior on theleft to posterior on the right. Sections from the other animals were similar to these.
