Answers

(1) Most of the peri-ictal aggressive behaviours appear as “defensive aggression”, viewed as a reaction to surrounding people who try to interact with the patient during the ictal/peri-ictal period. (Tassinari CA, Tassi L, Calandra-Buonaura G, et al. Biting behavior, aggression, and seizures. Epilepsia 200b; 46: 654-63.)


(2) The amygdala (and connected regions of the medial hypothalamus). (Davidson RJ, Putman KM, Larson CL. Dysfunction in the neural circuitry of emotion regulation: a possible prelude to violence. Science 2000; 289: 591-4.)
