53 rabbits were used as experimental animals. Electrical activity of theneurons in areas A_(0-2) L_(3-5) and H_(2-7) of the amygdala were recorded byglaos mscroelectrode. Electrode. Electrical stimulation of the peroneal nerveand pinching the rabbit's ear were used as nociceptive stimulations

Electricaldischarges of 461 amygdala neurons were observed

among which there were216 (47%) pain sensation neurons

242 (52.3%) neurons not related to pain

and 3 (0.7%) double phase neurons (i.e. neurone which began with excitationor inhibition followed by inhibition or excitation). Among the pain sensationneurons there were 112 (52%) pain inhibitory neurons in which nociceptivestimulation caused a decrease or even an abolishment of the electrical discha-rges

and there were 104 (48%) pain excitatory neurons in which an increasein electrical discharges were observed.
