Averaging of the brain magnetic signals
We observe in MEG records triangular peaks, which precede for about 700 ms the instant of the self-paced finger movement. Amplitude of the peak varies considerably from trial to trial. This makes possible separation of trials into groups, where the brain behaves differently during planning and execution of the same action. Separation into groups reveals other processes, active in the cortex before voluntary movement.

Spectral analysis of cardiointervalography of uneven time series for estimation of human activity vegetative support
Basic methods of rhythmogram spectrum estimation use well developed regular time series theory. There are different methods of reduction to a regular time grid, such as smoothing, approximation values, etc. Although the quality of these methods is sufficient when using a quasi-uniform rhythmograms but in the case of dynamic changes of heart rate caused by the normal functioning in the social environment may give incorrect results. The paper presents a method of spectral estimation of rhythmogram time series that permits a further spectral analysis with sufficient details.

Ensembles of synapses as candidates for the role of structures that encode semantic properties in artificial neural networks
This research addresses the issue of searching ANN structural elements which disentangle semantic properties of the input signal and directly encode network responses at the output. It is shown that ensembles of synapses in ANN could be such structural elements for some types of networks. The research considers the possible ways of encoding semantic properties in ensembles of synapses. By the example of a trained ANN, the author proves the existence of such ensembles and shows a significant difference between the role of synapses placed both within and outside of the ensembles.

About models of artificial neurons of aggregational type
A new class of models of artificial neurons is described in this work. These models are based on some assumptions: 1) contributions of synapses are summing with the help of certain aggregation operation; 2) contribution of complex synapse or synaptic cluster is computed with the help of another aggregation operation on the set of simple synapses. These models includes a big part of known functional models of neurons.

Creation of spiking neural networks with desired properties using empirical models
Relationships between neuron properties, structural characteristics of spiking neural network and its behavior cannot be obtained in explicit analytical form even for simplest neuron models and homogenous networks. It is proposed to use for this purpose empirical models produced by multiple adaptive regression splines and other data mining methods. This approach is illustrated for neural network consisting of LIF neurons with homeostatic properties.

Modeling of predictions by fishes studying labyrinths
The initial stage of modeling of cognitive abilities of the fishes studying labyrinths is presented. The model of the generation of fish’s predictions is constructed. According the model, fish prediction assurance increases. The results of computer simulations agree qualitatively with experimental biological data.

Development of neuron-like control system for dummy agent in a dynamic environment
The article discusses the process of building and architectural features of the neural network control system of the animat body placed in dynamic environment. Animat body is a complex dynamic object with many degrees of freedom. Considered control system solves two problems: links body components together into a single system and provides basic body reactions to external dynamic influences.

GALA: Group Analysis Leads to Accuracy, a novel approach for solving the inverse problem in exploratory analysis of group MEG recordings
Although MEG/EEG signals are highly variable between subjects, they allow characterizing systematic changes of cortical activity in both space and time. Traditionally, to discover sources of such activity a two-step procedure is used. The first step is a transition from sensor to source space by the means of solving an ill-posed inverse problem for each subject individually. The second step is mapping of cortical regions consistently active across subjects. In practice, however, the first step often leads to a set of active cortical regions whose location and activation timecourses display a great amount of interindividual variability hindering the subsequent group analysis. Here we propose Group Analysis Leads to Accuracy (GALA) - a solution that combines the two basic steps into one. In contrast to many other methods GALA takes advantage of individual variations of cortical geometry and sensor locations. Our method exploits the ensuing variability in electromagnetic forward model as a source of additional information. We assume that for different subjects functionally identical cortical regions are located in close proximity and partially overlap and their time courses are correlated (but not identical). This relaxed similarity constraint on the inverse solution can be expressed within a solid probabilistic framework, allowing the development of an algorithm to solve the inverse problem jointly for all subjects.

Analysis and possible directions of the reengineering of self-organizing neural systems based on convergence technologies
Analysis of mechanisms of neuron’s intracellular information networks allow to reveal the basics of associative and predictive properties of living systems at the molecular level. On the basis of the convergence of technologies it is likely to make it possible to develop molecular neural information nuclei capable as their living prototypes to self-organization in complex with the functional architecture like a brain and the ability to perform fairly complex cognitive functions.

Analysis of neuronal sensitivity to input signals with the help of neuronal ensemble model
Analysis of neuronal sensitivity to input signals is performed by using a realistic model of the statistical ensemble of Hodgkin-Huxley-type neurons, formulated in terms of the refractory density. The amplitude of current step stimuli and the noise amplitude are varied. The model reproduces known experimental data of many-trial patch-clamp recordings of spiking activity in single neurons, which reveal rapid reaction of the population firing rate to the stimulus changes.

Some temporary features, those evokes responses of neurons in the auditory system
In the vertebrate brain there are several consecutive nuclei those proceed the analysis of the received sound. This analysis based mainly on the identification of temporal characteristics of the signal in different frequency channels. Due to the nonlinearity of neuronal processing, correlation approach is insufficient for understanding these processes. Some methods to assess the contribution in the neuronal response the instantaneous amplitude and the rate of amplitude changes. The example of their application is presented.

Multifractal analysis of tremor of the human hand under the motor dysfunction
Multifractal properties of involuntary shaking (tremor) arising during the performance of the motor task (sustaining effort of fingers under isometric conditions) have been examined. The wavelet and multifractal parameters have been gained. These parameters allow us to find correlations between clinic symptoms of tremor before the antiparkinsonian treatment, their decrease after drug administration and changes of the parameters. The suggested analytic approach for study of integrative activity of the central nervous system during realization of the motor task enables to estimate quantitatively the degree of deviation of the motor function from the healthy one.

The peculiarities of the viewing trajectory local elements: object-return gaze fixations
The results of experimental data analysis about the features of the return fixations during the complex images and textures viewing are presented. It is shown that the duration of fixations and saccadic amplitude in the vicinity of the return fixations differ from the average values of these parameters. The possibility of using the results obtained to develop a model that provides a realistic simulation of the viewing trajectories in specific psychophysical tests is considered.
