Figure 3. WKY rats lack LTP of BLA-evoked responses in the PL cortex.

Figure 3

LTP was assessed in BLA-evoked responses of naïve Sprague Dawley (SD, open circles, n=8) and Wistar Kyoto (WKY, closed circles, n=8) rats following theta-burst stimulation (TBS). All data is expressed as percent of baseline. Arrows represent three sets of high frequency stimulation used to induce LTP. The dashed line represents baseline. Each data point is the average of 30 consecutive sweeps (5 min). BLA-evoked responses were followed for 60 min after the induction of LTP. BLA-evoked responses expressed robust potentiation following TBS, however, this result was not observed in WKY rats. At 60 min post TBS the evoked response of SD, but not WKY rats was significantly potentiated above baseline.
