Hippocampal Infusion of Zeta Inhibitory Peptide Impairs Recent, but Not Remote, Recognition Memory in Rats

Figure 2

Preference for the novel object after infusion for recent and remote memory conditions. In the recent memory condition, all groups performed above chance, but rats with ZIP infusions (red) performed worse than rats with aCSF infusions (blue) and control (white) rats. In the remote memory condition, both ZIP (light red) and aCSF (light blue) groups performed similarly and above chance. Error bars indicate SEM. Asterisk indicates difference from aCSF and control groups (). All groups performed above chance (, chance = 50%).
