FIG 3. Normalized ADC values after pilocarpine-induced seizures.

Contrasting ADC (with standard error of the mean) changes were found between different limbic regions. The piriform cortex (and amygdala) show significant ADC decreases as early as 12 hours that are still present at 24 hours. Conversely, the hippocampus displays a slow increase in ADC that is significantly elevated at 24 hours. The retrosplenial cortex shows a decrease in ADC that peaks at 12 hours but returns to control levels by 24 hours.
