[Dynamics of Brain Activity during Voluntary Movement: fMRI Study].

The use of event-related fMRI makes it possible to investigate spatio-temporal dynamics of cortical and subcortical human brain structures activity during voluntary movement performance in response to presentation of relevant verbal stimuli. The results of the study showed that voluntary movement was associated with higher contralateral brain activation in a number of areas: primary motor and somatosensory cortex, premotor cortex, supplementary motor area and insula with adjacent regions. Ipsilateral activation of the cerebellum also was observed.

[Information processing and brain metabolic characteristics in patients at ultra-high risk for endogenous psychosis].

Objective: Functional and structural brain abnormalities in people at high risk for psychosis is a subject of intensive studies in biological psychiatry over the last decades. We studied correlations between neurophysiological and neuroimaging parameters in ultra-high risk patients.

Material And Methods: Fifty-six patients, aged 17-25 years, with nonpsychotic mental disorders were examined.
