Figure 4.
Changes in [lac] in response to acute electrical stimulation are augmented beginning 24hrs after induction of LTP. A) Average change in [lac] in response to acute electrical stimulation across all rats at each stimulation time point. Each tracing depicts 25s of [lac] (including 5s prior to stimulation). BCDE) Changes in [lac] following acute electrical stimulation before and after LTP induction. 24hrs after LTP induction, the initial decrease in [lac] following stimulation is both significantly larger (B) and faster (C) while the magnitude of ensuing [lac] overshoot is also significantly increased (D). **p<0.01, *p<0.05, and ^p<0.10 as compared to baseline (BL).
