Figure 3: Representative intracranial EEG recordings from the different brain regions studied and obtained from three different rats in the NaCl, CBX, and quinine experimental groups ( each one) in which spontaneous fast ripples (FRs) were observed: right anterior hippocampus (RAH) and right posterior hippocampus (RPH) before, during, and at different times after drug administration. Note the effects of CBX and quinine on the FRs.
