A typical example of nociceptive discharges evoked by peripheral mechanical stimulation. A. The top trace represents an ECoG. The second trace is multiple unit discharges evoked by mechanical stimulation. The third trace is an EEG recorded via stimulating electrodes in the BLA. Nociceptive stimulation also induced EEG changes. The bottom trace represents a pressure curve. B. Durations of responses and post-stimulus discharges (PSD) are shown as a histogram. One bin is 500 msec. Vertical lines represent the stimulus starting point and the horizontal broken line represents the mean level of spontaneous discharges.
