Figure 5From: Impact of cognitive stimulation on ripples within human epileptic and non-epileptic hippocampusObservations from a single contact within the non-epileptic hippocampus of subject (patient no. 6). Bottom to top the transient post-stimulus decrease in ripple occurrence within non-epileptic hippocampus coincides with event related 80–250 Hz power envelope reduction, the genesis of local-field cognitive potential (P3).
