Experiments were performed in chronically operated cats first awake and thereafter anesthetized with pentobarbitone, 16-20 mg/kg i.v. Stimulation of the central amygdala in awake cats elicited an arousal reaction seen in cortical and hippocampal EEG, and in muscle activity of dorsal neck muscles. Concomitantly therewith were autonomic system reactions(More)
Auditory cortical evoked potentials of 20 schizophrenic patients with an acute exacerbation of the illness were investigated before neuroleptic medication and after remission of the acute symptoms, and compared with healthy controls matched for sex and age. Additionally, tests were conducted in 40 healthy volunteers to ascertain whether psychoticism or(More)
Baroreceptor control of heart rate was studied in 14 unanaesthetized cats during rest and arousal induced by either electrical stimulation of the central nucleus of the amygdala or by natural stimuli. The baroreceptor reflex was elicited by i.v. injections of angiotensin II and the sensitivity of the vagal component of the reflex expressed as the regression(More)
Bipolar electrical stimulations of the rostal hippocampus and of the amygdala were performed at irregular intervals in wakeful unrestrained cats via chronically implanted glass-insulated stainless steel electrodes. The excitability of the stimulated tissue remained unchanged during the whole investigation period of six months up to one and a half years, as(More)
1. Stimulation of the central amygdala, postero-lateral hypothalamus and locus coeruleus in cats resulted in a sustained increase in arterial pressure, an increase in heart rate, with a poststimulation bradycardia and an increase in peripheral resistance (vasoconstriction in the vessels of the hindlimbs). The behavioural pattern was characterized by an(More)
Intravenous injections of gammahydroxybutyric acid (GHBA) (150-200 mg/kg) induce desynchronized sleep (DS) in the cat. This was shown by recording the EEG, eye-movements, the neck EMG, heart-rate and arterial pressure. The decreases in arterial pressure were not different from those recorded during naturally occurring DS. GHBA, given at doses above 200(More)
