(D) Extracellular recordings (fEPSPs) in hippocampal brain slices from 1.5 months-old WT (CSPα+/+/α-syn+/+) and CSPα+/-/α-syn+/- mice. The left panel shows representative fEPSP traces. Summary graphs show the fEPSPs slope as a function of either the applied stimulus intensity or the prevolley amplitude. Data are the average of the values from 5 slices (from 4 mice) in the WT group and 5 slices (from 4 mice) in the CSPα+/-/α-syn+/-. *p<0.05, repeated measure ANOVA.
