Averaged EMGs were recorded from the elbow- and shoulder-operating muscles in 10 adult men during parafrontal slow test movements of the hand performed within the horizontal plane. The movements between the left and right end-point positions were carried out with a constant 4 cm/sec velocity in both directions consequently; two identical isotonic l...

Effects of injections of titanium dioxide nanoparticles into the medullary nuclei involved in cardiovascular control (nuclei reticularis paramedianus, reticularis lateralis, and ambiguus) on the blood pressure and heart rate were examined in rats. The nanoparticles (TiO2, PlasmaChem GmbH, D-12489 Berlin, Germany) were used in the form of a nanopowd...

The problem of recognition of emotions in humans is still open from a few aspects. In our study, we used a deep learning method named stacked autoencoder to classify regions of four emotional states in valencearousal plane (high valence-low arousal, high valence-high arousal, low valence-low arousal, and low valence-high arousal). We used a number ...

Temporal summation of pain (TSP) is a promising tool for measuring the pain modulation processes in healthy subjects and patients with chronic pain. We tried to find optimal stimulation parameters in order to elicit a robust reproducible TSP phenomenon. Twenty healthy volunteers (15 women and 5 men) completed four sessions/conditions of pulsating h...

We investigated changes in the EEG signals and the latency of behavioral responses in the cognitive test with interfering emotional stimuli. It was hypothesized that the cognitive process would be not only influenced by emotional factors but would also result in different patterns by emotional types (e.g., annoyance, happiness, neutrality, etc.) We...

Electroencephalograms of 220 patients with post-coma disorders of consciousness after severe traumatic brain injury were analyzed using nonlinear multidimensional analysis, and the results were compared with those of standard linear time-amplitude analysis. Quantitative multichannel EEGs were recorded in the course of one-year-long clinical restora...

We examined the effects of introduction of melatonin in different time modes on morphofunctional parameters of serotonergic neurocytes of the rat hypothalamic arcuate nucleus (cross-sectional area of the neurocyte nuclei, content of serotonin vesicles per neuron, and number/density of serotonergic neurons); general levels of tryptophan and serotoni...

Several studies have highlighted a high comorbidity between epilepsy and autism. We hypothesized that some similar etiological factors might affect both disorders; among such factors, gut microbiome neurotoxins may participate in the development of these neurological disorders. We found that course (21 day) i.p. injections of a gut microbiome toxin...

In this theoretical study, two-joint equilibrium muscle contractions were simulated to determine the end-point forces created by the hand of the human right upper limb within the horizontal plane. For invariable frontally directed end-point forces, 3D surfaces simulating joint torques (JTs) at the shoulder and elbow joints are reconstructed by defi...

Human nerve growth factor-β (hNGF-β) plays a major role in the development and survival of the central and peripheral nervous systems; therefore, it can, in principle, be used as a therapeutic agent for the treatment of neurodegenerative diseases. As was shown, hNGF-β stimulates neuronal differentiation in vitro and regulates the expression of neur...
