MEG data analysis using empirical mode decomposition

In the present paper it is proposed to use the empirical mode decomposition method for frequency bands analysis of MEG data, and the method is compared with the classical method of narrow band filtration and Hilbert transform. By the example of MEG data recorded during performing volitional sensorimotor activity by the subjects, it is shown that the procedure of extraction of empirical modes can detect useful information which is inaccessible to classical methods of frequency bands analysis.

Self-organization of neuronal discharges in the cortex initiating action

With MEG we observe synchronous trains of beta-oscillations in different cortical areas before the start of self-paced finger movement. We conjecture, that these oscillations align neural trajectories in these cortical sites. This is the ordering process similar to formation of bird flocks, which brings the system of neurons into the state of self-organized criticality. System in this state can quickly react on relevant stimuli and ignore irrelevant ones. We discuss the role of alpha, beta and gamma rhythms in attention

Deep recurrent neural networks for extracting pharmacological terms from Russian texts

Recent studies have highlighted importance end-user reviews analysis for monitoring potential side effects of pharmaceuticals. In this work we apply deep recurrent neural networks, that recently have shown superior capabilities in term extraction tasks, for automated detection of important pharmacological terms in online reviews, posted by users of phramacological substances. We demonstrate that a many terms, can be reliably extracted this way using only a small (50k words) training dataset, and used for computing important statistics on drug usage. While accuracy of extraction of some other terms, such as perceived efficiency of the drugs was poor. We discuss possible strategies for improving our results and potential applications in pharmacovigilance.

Wavelet and multifractal estimation of the intermittent photic stimulation response in the electroencephalogram of patients with cerebrovascular disturbances

The task is to estimate the degree of responses to intermittent photic stimulation for subjects with cerebrovascular disturbances. This degree is evaluated on the basis of analysis of changes in multifractal and wavelet properties of electroencephalographic (EEG) patterns taking place during the photic stimulation. The degree of multifractality of EEG patterns does not change considerably during the stimulation. By contrast, the coefficients of photic driving and holding and the energy increase times gained by the wavelet spectra in EEG patterns of patients with cerebrovascular disturbances differ significantly from the characteristics determined for the healthy subjects.

THE PERCEPTION OF SMALL LIGHT SOURCES RIMLESS ALSO CAN MANIFEST IN THE FORM OF THE "SPECIFIC VISION DEFICIT" PATCH

The study of the mysterious "specific vision deficit" (SVD) phenomenon is continued. The essence of the SVD phenomenon is the sensation of seeing a dark patch (SVDp) in a small hole (diaphragm) in the lumen, as previously described. In the work it was found that patch, having all the SVDp characteristics, may also occur in the perception of a number of other light sources. This fact opens new possibilities in the study of the SVDp nature. This paper describes these sources and also the properties of the created by them SVDp.

MECHANISM OF SYNCHRONIZED BURSTING IN THE NEURONAL CULTURE MODEL ON THE BASIS OF NEURON WITH AUTOREGULATION

The paper presents a neural network model that exhibits synchronized bursting activity. It is recurrent network formed on the basis of modified Leaky Integrate-and-Fire neurons. Extended vector of the current state of the neuron is introduced. It contains information about both its own ability to generate spikes and the current activity of the presynaptic neurons. We have refused a widespread model of long-term synaptic plasticity STDP and worked out a new learning rule for synaptic weights. The recurrent neural network with the proposed model of a neuron shows activity in the form of synchronized bursts, as it occurs in neuronal cultures. The simulation results are presented. Prospects of application of the model to study the mechanisms of learning in the neuronal culture in vitro are discussed.

On the Spatial Dynamics of a Network Spike in Neuronal Cultures

It is shown that in the model two-dimensional neuronal cultures there exist a few spatial nucleation centers of a network spike, from where the synchronous spiking activity propagates in the network as single circular traveling waves. The number and spatial locations of the nucleation centers are unique and steady for a given neuronal network, and these quantities vary over the different networks. A functional role of inhibitory neurons is specified qualitatively. The obtained results are consistent with experimental observations.

Algorithms to generate realistic astrocyte networks for neuro-glial modeling

Astrocytes have intricate structure and complex dynamics. They play a pivotal role in organizing patterns of neuronal network activity. Theoretical studies of neuron-glia interactions require a way to generate spatial structures resembling real astrocytic networks. This study offers two approaches to create such patterns: a data-driven one and generative approach. Discussed are the ways to account for neuronal synaptic activity in the context of the dynamics of the spatially detailed models of astrocytic networks.

We propose a minimal model of color and orientation processing in the primary visual cortex, based on novel experimental data. The model is constructured as a network of neuronal populations distributed in the feature space of color and orientation. The network has a toroidal topology. The populations are described by the rate model. The torus-model reproduces known characteristics of the color-sensitive neurons’ behavior and predicts some effects associated with a perception of color hue for gray non-oriented or two-color stimuli.

Temporal analysis of the sound in auditory system of the frog

We investigated the mechanisms of temporal analysis of audio signals in the frog’s medulla and midbrain neurons. Extracellular activity was recorded in two nuclei of the auditory pathway of the grass frog (Rana t. temporary): dorsal medullar nucleus and torus semicircularis. An analysis of the statistical properties of background activity provided information about intrinsic properties of single units. The slow changes in unit’s sensitivity demonstrates the adaptive behavior of auditory neuronal ensembles. In the process of neuron’s adaptation to continuous signal, its ability to recognize small amplitude changes improves significantly. We studied signal envelope features that caused neuronal spike generation during long tone that was amplitude modulated by repeatable -wave of envelope function, but more central neurons were often responsive to the rate of change in amplitude and even to its acceleration.

About sigma-pi neurons of aggregation type

A new class of models of artificial neurons is described in this work. These models are based on the following principles: 1) contributions of synapses are summed with the help of certain aggregation operation; and 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 include a big part of the known functional models of neurons. For a class of the aggregating neurons generalizing model sigma-pi neuron, it is shown that they can be correctly trained on the final sets of precedents.

For several reasons very complex functions couldn’t be realized by one table. The main reason is “dimensionality damnation”, interpolation basic points number exponential growth with Y=F(X,A) dimensionality increase.

Multiple goal pursuit -- to kill two birds with one stone or to fall between two stools ?

We present the simple phenomenological (but - analytic) model allowing to formalize description of multitasking, i.e. simultaneous performing several tasks. That process requires distribution of attention, and for great number of goals do not lead to success. Our consideration shows that simultaneous performing more than two tasks is, most likely, impossible.

Principles of discrete simulation heterogeneously mechanisms in nervous systems

New principles for the functioning of neurons are proposed. The model of neurobiological neuron formalizes the diverse types of neurons and is an extension of the model by McCulloch and Pitts. Neuron, analogously to the classic ("electrical") model, can be in one of two states (active and passive); however, unlike electric models, it "sees" not all the signals that it receives, but only those, which correspond to the types of its receptors.

INSTANTANEOUS WAVELET PHASE CORRELATION OF ELECTROEHCEPHALOGRAM SIGNALS

We developed a new algorithm to detect instantaneous phase correlation of nonstationary electroencephalogram (EEG) signals registered from different leads of the cerebral cortex. The method is based on the continuous wavelet transform (CWT), using the Morlet mother wavelet with a control parameter that allows you to change the spectral and temporal resolution of the signals under study. The algorithm includes phase straightening procedure, eliminating the critical points in the CWT phase behavior at the boundaries of the interval [0;2Pi]. We tested the approach by calculating phase correlation in time of two EEG signals.

PERSONAL CRYPTOGRAPHY USING ARTIFICIAL NEURAL NETWORKS

The paper presents a method of generating encryption algorithms using neural networks. Based on the application of natural noise sources we ‘teach’ a system to approximate the input noise with the aim of generating an output nonlinear sequence. This output is then treated as an iterator which is subjected to a range of tests to check for potential cryptographic strength in terms of metric. This approach provides the potential for generating an unlimited number of unique PRNG.
