[Localization of human brain areas activated for chaotic and ordered pattern perception].

The aim of our work was to localize cortical areas involved in the processing of incomplete figures using functional MRI (fMRI) for 8 healthy volunteers (18-30 year old) with the did of anatomical and fMRI fast imaging technique: echo planar imaging (EPI), whole brain scan (36 slices) matrix 64 x 64, 3.7 second. We used 1.

[The subcortical neuronal correlates of human assessment actions].

In patients with parkinsonism to whom in accordance with medical-diagnostic indices electrodes were implanted into the nuclei of thalamus and striopallidal system, impulse activity of neurones was recorded in tests with presentation of visual and acoustic stimuli. It has been shown that neurones of these structures, reacting by a change of discharges frequency in carrying out the assessing actions by man constitute a special class of neurones, spatially separated from those, connected with the organization of motor acts. The typical feature of neuronal reactions is a high degree of their value dependence on the level of attention.
