Journal ArticleDOI
Localized near–infrared spectroscopy and functional optical imaging of brain activity
TL;DR: Observations suggest an application for NIRS in psychiatric disease management, as an addition to clinical monitoring at the bedside, and time resolved 64-channel optical imaging system was constructed.
Journal ArticleDOI
Dominance of the ‘nondominant’ hemisphere in depression
TL;DR: Patients with major depression diagnosed by DSM-III-R are examined to find and qualify disturbances in brain oxygenation and hemodynamics during a psychological task, finding the nominally 'nondominant' hemisphere may become dominant during the course of depression.
Journal ArticleDOI
Impaired interhemispheric integration in brain oxygenation and hemodynamics in schizophrenia
TL;DR: Patients with chronic schizophrenia are examined to find and qualify disturbances in interhemispheric integration in brain oxygen metabolism and hemodynamics during a psychological task and certain schizophrenic symptoms may be related to defective interhemisphere integration.
Journal ArticleDOI
Desensitization of β-Adrenergic Receptor-Coupled Adenylate Cyclase in Cerebral Cortex After In Vivo Treatment of Rats with Desipramine
TL;DR: Functional uncoupling of the N protein from receptors was responsible for early development of desensitization of β‐adrenergic receptor‐mediated adenylate cyclase in the cerebral cortex during desipramine therapy.
Journal ArticleDOI
Gender- and handedness-related differences of forebrain oxygenation and hemodynamics.
TL;DR: NIR results showed that a large majority of women used both sides of the brain when concentrating on carrying out the MDT, whilst most men, especially left-handers, reacted mainly using the hemisphere which was 'dominant' according to handedness.
