The expression of Arc in the fascia dentata (FD) is correlated with spatial memory performance in the Morris swim task. Within individual animals, the proportion of granule cells in the suprapyramidal blade of the FD expressing Arc 480 minutes following spatial processing is significantly correlated with performance during spatial trials (A), but not probe trials (B) in the Morris swim task. The number of granule cells expressing Arc in the infrapyramidal blade significantly correlated with both spatial trial (C) and probe trial (D) performance.
