[Mismatch negativity and its hemodynamic equivalent (based on fMRI) in research of speech perception in healthy and in speech disorders].

The review is devoted to the use of electrophysiological index of auditory discrimination, known as "mismatch negativity" (MMN), and its hemodynamic equivalent obtained by functional magnetic resonamce imaging (fMRI) to study speech perception in normal and pathological conditions. Most attention is paid to works with using MMN as a neurophysiological index of the phonemic hearing impairment in patients with sensory aphasia. The MMN applicability for examination of speech compensation degree is substantiated.

[Changes of EEG power spectrum in response to the emotional auditory stimuli in patients in acute and recovery stages of TBI (traumatic brain injury)].

We investigated variability of responses to emotionally important auditory stimulation in different groups of TBI (Traumatic Brain Injury) in acute state or recovery. The patients sampling consisted of three different groups: patients in coma or vegetative state, patients with Severe and Moderate TBI in recovery period. Subjects were stimulated with auditory stimuli containing important physiological sounds (coughing, vomiting), emotional sounds (laughing, crying), nature sounds (bird song, barking), unpleasant household sounds (nails scratching the glass), natural sounds (sea, rain, fire) and neutral sounds (white noise).

[Brain mapping in verbal and spatial thinking].

The goal of this study was to describe the topography of the active cortical areas and subcortical structuresin verbal and spatial thinking. The method of functional magnetic resonance imaging (fMRI) was used. 18 right-handed subjects participated in the study.

[Human cognitive space: coincidence of the models, built on base of EEG rhythms and psychometric measurements].

Earlier it was shown that the specific rhythmical EEG patterns appear during solution of the particular cognitive tasks, such as spatial and verbal ones. In this study not only basic, but also mixed, intermediate cognitive tasks were used. The aim was to estimate the similarity and the difference between EEG spectra during performance of the whole line of the thinking operations.

["Brain reading": achievements, perspectives and ethical problems].

The new trend in brain research designated as brain reading is considered. This research deals with decoding the informational content of the brain processing via its physiological parameters. Such studies are based on rather complicated methods of mathematical analysis.
