Four-dimensional spherical model of emotions was built with metric multidimensional scaling method. This model simultaneously describes emotional expressions in the oral human speech (based on the samples of the word “Yes”, spoken with different expressions) and vocalizations of rhesus macaque monkeys in the human listener’s perception. Based on statistical criteria, number of dimensions in the space of the perception of emotional human speech and monkey vocalizations samples was defined to be equal to 4. Stimuli points in the space are positioned in almost equal distance from the center of the hypersphere. Model space axes were interpreted in regard to the contents of human emotions. Orientation of perception of monkey vocalization samples space axes was conducted in a formal procedure based on direct experimental data — cross-assessment of the differences between some human speech samples and all monkey vocalizations samples. As a result, all studied monkey vocalizations samples were quantitatively presented in a unified system of the characteristics, defined for human emotions, and received an anthropomorphic interpretation. Obtained results are not controversial to the data from animal behavior observation and expert analysis of their vocalizations range. We revealed the similarity between emotional expressions in human speech and monkey vocalization range, which, in turn, demonstrates the relation of human and monkey emotions.

We examined 26 women in age 69±4.5. Neuropsychological tests analyzed different aspects of memory: capacity, activation, executive control. MRI-volumetry of hippocampus was performed using voxel-based morphometry. Our findings corroborated the idea of lateral asymmetry of hippocampus: left hippocampus is mostly involved in verbal information processing and control: right hippocampus participates in activation processes supporting memory consolidation. Significant correlation was found between anterior left hippocampus, time perception and subjective duration. Posterior left hippocampus was significantly related to spatial perception and reconstruction. Body of left hippocampus as compared with its anterior and posterior parts was associated with activation processes necessary for information to be memorized properly.
We discussed the brain mechanisms of audiovisual integration and semantic comprehension as a direct process of comprehension (early integration) and process with second tuning (late integration) necessary in conflict situations. Existing of such audiovisual semantic conflict and four strategies to solve it were obtained in psychophysical experiment. Mathematic models were formulated according to that data. All models were described by linear equations, which were noted for the different weights of contributions of audio and visual modalities.
Brain mechanisms of subjective (internal) rhythmisation were examined in two experimental cases. One of the tasks was to combine acoustic rhythmic clicks as pairs; another task was to combine the same monotone clicks as triples. With the method of factorial analysis some types of specific variation of EVP form on the clicks which took different place in patterns were figured out. Analysis of dynamics of brain structures activity revealed some types of functional brain architectonics while subjects were performing a task of combining clicks. Specific cerebellum activation took place both in rhythm perception and in subject’s activity of integration of cognitive processes. This took place when subject used hierarchical strategy of rhythm perception.
