Diffusion of [³H]muscimol away from the site of infusion (experiment 3). Mean ± SEM apparent density from tissue sections taken throughout the rostrocaudal extent of the hippocampus. Sections from each rat having the maximum density throughout the infused area were placed at distance zero; all other sections were placed according to their relative distances from those sections. Rats were killed at one of four time intervals after [³H] muscimol infusion: immediately (0 min; white circles), 20 min (light gray circles), 60 min (dark gray circles), or 360 min (black circles).
