Hippocampal Regulation of Postsynaptic Density Homer1 by Associative Learning

Figure 6

mRNA expression of Homer1a, Ania-3, and long Homer1 in the hippocampus following the recall (a–c) or extinction (d–f) of contextual fear memory. mRNA expression is represented by mean ± SEM standardised optical density values, normalised to no recall controls (100%). Brains were taken 30 min or 2 h after reexposure. (30 min), (2 h), or (no recall) per group. Asterisks represent significance of the groups versus no recall control (, , and ).
