The use of electroencephalography in the practice of psychiatry

The supramammillo–septal–hippocampal pathway mediates sensorimotor gating impairment and hyperlocomotion induced by MK-801 and ketamine in rats

“…A similar increase in gamma oscillations was observed in subjects after receiving psychotomimetic drugs (Itil and Itil 1986;Saletu et al 1972), whereas antipsychotic drugs normalized gamma EEG and improved psychotic symptoms in schizophrenics (Akpinar et al 1993;Itil 1982;Serafetinides et al 1972).…”

“…Schizophrenic patients have been reported to show higher amplitude of fast (gamma) waves as compared to normal control (Akpinar et al 1993;Baldeweg et al 1998;Clementz et al 1997;Lee et al 2003). In addition, antipsychotic drugs were reported to suppress the fast EEG activities in schizophrenic brains (Akpinar et al 1993;Itil 1982;Serafetinides et al 1972) or those induced by a psychotomimetic drug (Itil 1982). These findings suggest a close relationship between gamma waves and human schizophrenia as well.…”

“…However, the increased hippocampal gamma oscillations in animal models of schizophrenia and the fast EEG recorded on the scalp of schizophrenic patients (Baldeweg et al 1998;Itil 1982;Itil and Itil 1986;Lee et al 2003) may suggest that intracortical processing is abnormal during enhanced gamma oscillations.…”

Electroencephalography of DSM‐III borderline personality disorder

“…Slow-wave activity is generally considered to be related to delayed cerebral maturation. The observation that antisocial personality reflects cortical immaturity is known as the "maturational retardation" hypothesis (6). Consistent with this hypothesis is the observation that personality disorders seem to decrease with age.…”

Clinical Electroencephalography and the Study of Suicide Behavior

“…Among other things, EEG is sensitive to cerebral electrical dysregulation caused by underlying diffuse and focal cerebral disturbances, encephalitic processes, vascular lesions, endocrinological and metabolic disorders, nutritional disorders, exposures to toxic substances, pharmacotoxicity, and idiopathic and iatrogenic seizures of various kinds (Gibbs & Gibbs, 1964; Kooi, 1971; Kiloh et al, 1972; Klass & Daly, 1979; Rémond & Glaser, 1977; Rémond & Radermecker, 1977; Wilson, 1965b). The value of this wide spectrum of sensitivity to screening patients with emotional or psychiatric complaints has been stressed elsewhere (Itil, 1982; Lutz, 1982; Struve, 1985).…”
