Figure 3.

(A) The water access and the DID had no effect on baseline recordings of PS amplitude (PSA) and fEPSP slope (n = 5). (B) A tetanization given after undeprived animals had started to drink (spontaneous drinking) did not lead to a reinforcement of the potentiation of PSA and fEPSP slope (n = 5). (C) A weak intermittent footshock resulted in slight changes of PSA and fEPSP slope, that were, however, relatively short lasting and not statistically significant (n = 5). (D) The delivery of footshock resulted only in a slight short-term increase of the intrahippocampal temperature of about 0.4°C (n = 5). Data are plotted as average change from baseline (mean ± SEM).
