Figure 5. Reduced gamma oscillations in hippocampal slices of EAE mice.

Figure 5

A) Spectrogram against time, showing the increase of PSD in the frequency range of 30 to 50 Hz, induced by Cch (20 µM) in the CA1 area of a CFC mouse hippocampal slice. PSD is expressed with a colorimetric scale, measured in successive 1 min epochs. The traces on top are local field potentials recorded in the CA1 pyramidal layer, before (left) and during (right) Cch perfusion. B) Histograms (mean ± S.E.M) of the change in PSD area in Cch (20 µM), for the range of frequencies indicated on top, relative to corresponding measurements obtained before Cch perfusion, in slices from CFC (n = 9) and EAE (n = 9) mice. The scattered dots on each column are single experimental data. * indicates p<0.05, t-test.
