A ten-layer feed forward network is constructed in the presence of an exogenous alternating magnetic field. Specifically, our results indicate that for rate coding, the firing rate is significantly increased in the presence of an exogenous alternating magnetic field and particularly with increasing enhancement of the alternating magnetic field amplitude. For temporal coding, the interspike intervals of the spiking sequence are decreased and the distribution of the interspike intervals of the spiking sequence tends to be uniform in the presence of alternating magnetic field...

The aim of this study is to determine whether the dentate neurons can be translaminary neuromorphotopologically classified as ventrolateral or dorsomedial type. Adult human dentate 2D binary interneuron images are used for the purposes of the analysis. The analysis is performed on the real and the virtual neuron sample. The total of 29 parameters is used. They can be divided into the classes: neuron surface, shape, length, branching and complexity. The clustering is performed through the algorithm consisted from of the steps of predictor extraction (matrix attractor analysis/non-negative matrix factorization and cluster analysis of predictor factors, separate unifactor analysis/Student's t-test and MANOVA) and multivariate cluster analysis set (cluster analysis, principal component analysis, factor analysis with pro/varimax rotation, Fisher's linear discriminant analysis and feed-forward backpropagation artificial neural networks)...

White matter (WM) asymmetries of the human brain have been well documented using diffusion tensor imaging (DTI). The purpose of this study was to investigate white matter asymmetry across the whole brain in cerebral small vessel disease (SVD) patients and evaluate the relation between the factors which often represent disease's existence and white matter asymmetry. A total of 105 nondemented elderly with cerebral SVD patients aged between 60 and 85 years were included in this study. All participants underwent T1 MPRAGE, fluid-attenuated inversion recovery and DTI scanning...

In this paper, a person authentication system that can effectively identify individuals by generating unique electroencephalogram signal features in response to self-face and non-self-face photos is presented. In order to achieve a good stability performance, the sequence of self-face photo including first-occurrence position and non-first-occurrence position are taken into account in the serial occurrence of visual stimuli. In addition, a Fisher linear classification method and event-related potential technique for feature analysis is adapted to yield remarkably better outcomes than that by most of the existing methods in the field...

There is growing evidence that placebos are able to influence visual perception. A previous functional magnetic resonance imaging (fMRI) study on the processing of disgust images demonstrated that a 'disgust placebo' (inert pill administered with the verbal suggestion of an anti-nausea medication) reduced visual cortex activity and connectivity. In the present fMRI investigation, we examined corresponding visual effects of a 'disgust nocebo' (an odorless substance introduced as an aversive smell that enhances disgust feelings)...

Accurate differentiation of mental fatigue levels by analyzing electroencephalogram (EEG) features is still a challenge. This deficiency is rooted in the inability of conventional EEG features to reveal significant changes amongst fatigue levels. From a different perspective, it is evident for evaluating the amount of alertness that characterizing the P300 component is widely used by performing a recognition task. The goal of this study is to classify the pre-task and post-task fatigue levels by tracking the spatial activation of their P300 sources compared to differentiating the P300 waveform features...

The advancement in medical research and intelligent modeling techniques has lead to the developments in anaesthesia management. The present study is targeted to estimate the depth of anaesthesia using cognitive signal processing and intelligent modeling techniques. The neurophysiological signal that reflects cognitive state of anaesthetic drugs is the electroencephalogram signal. The information available on electroencephalogram signals during anaesthesia are drawn by extracting relative wave energy features from the anaesthetic electroencephalogram signals...

Existence of allocentric and egocentric systems for human navigation, mediating spatial and response learning respectively, has been discussed so far. It is controversial whether navigational strategies and their underlying learning systems and, accordingly, the activation of their associate brain areas are independent/parallel or whether they functionally/causally interact in a competitive or in a cooperative manner to solve navigational tasks. Insights of neural networks involved in reward-based navigation attributed to individual involvement or interactions of learning systems were searched...

Systemic Kainic Acid (KA) administration has been used to induce experimental temporal lobe epilepsy in rats. The aim of this study was to evaluate the neuroprotective effect of rosemary extract (RE, 40% Carnosic acid) against KA-induced neurotoxicity in hippocampus and impaired learning and memory. Animals received a single dose of KA (9.5 mg/kg) intraperitoneally (i.p.) (KA group) and were observed for 2 h and were scored from 0 (for normal, no convulsion) to 5 (for continuous generalized limbic seizures)...

The continuing prevalence of a highly heritable and hypo-reproductive extreme tail of a human neurobehavioral quantitative diversity suggests the possibility that the reproductive majority retains the genetic mechanism for the extremes. From the perspective of stochastic epistasis, the effect of an epistatic modifier variant can randomly vary in both phenotypic value and effect direction among the careers depending on the genetic individuality, and the modifier careers are ubiquitous in the population distribution...

Attention deficit hyperactivity disorder is a neurodevelopmental condition associated with varying levels of hyperactivity, inattention, and impulsivity. This study investigates brain function in children with attention deficit hyperactivity disorder using measures of nonlinear dynamics in EEG signals during rest. During eyes-closed resting, 19 channel EEG signals were recorded from 12 ADHD and 12 normal age-matched children. We used the multifractal singularity spectrum, the largest Lyapunov exponent, and approximate entropy to quantify the chaotic nonlinear dynamics of these EEG signals...

Microorganisms demonstrate conscious-like intelligent behaviour, and this form of consciousness may have emerged from a quantum mediated mechanism as observed in cytoskeletal structures like the microtubules present in nerve cells which apparently have the architecture to quantum compute. This paper hypothesises the emergence of proto-consciousness in primitive cytoskeletal systems found in the microbial kingdoms of archaea, bacteria and eukarya. To explain this, we make use of the Subject-Object Model (SOM) of consciousness which evaluates the rise of the degree of consciousness to conscious behaviour in these systems supporting the hypothesis of emergence and propagation of conscious behaviour during the pre-Cambrian part of Earth's evolutionary history...

By means of EEG analysis the functional state of subjects with high and low levels of anxiety was studied in different periods preceding a cognitive task - a visual expression recognition. Several conditions were investigated: background/eyes closed; background/eyes opened; listening the instruction for the cognitive task; operative rest (time lapse between listening the instruction and the beginning of the task), as well as short intervals immediately preceding the exposition of target stimuli (stage of preparation) - pairs of faces pictures with identical or different emotional expressions...

In this study, we investigated, for the first time, facial expressions during the retrieval of Self-defining memories (i.e., those vivid and emotionally intense memories of enduring concerns or unresolved conflicts). Participants self-rated the emotional valence of their Self-defining memories and autobiographical retrieval was analyzed with a facial analysis software. This software (Facereader) synthesizes the facial expression information (i.e., cheek, lips, muscles, eyebrow muscles) to describe and categorize facial expressions (i...

Subject-object relations reflect the relation of phenomenology and physics and are at the centre of interest in brain research and neuro-psychology. The unresolved dichotomy behind this relation is one of the most challenging questions of our time. Setting out from causal modelling I suggest a particular topology for subject-object relations and argue that we can find a physical realization in living organism that provides a continuous transform between both domains. In a geometrical metaphor this transform has the topological properties of a one-sided surface or non-orientable flat...

Consciousness is the greatest enigma in human history. For centuries scientists and researchers have tried to describe it without coming to conclusions. In the last years with the neurosciences development, consciousness has become the common goal of numerous studies. But consciousness has always been studied only in humans, but after "Cambridge Declaration on Consciousness" in 2012, even non-human animalsthey feel possessed of the consciousness. According to "theory Orch-OR" of Hameroff and Penrose we have conducted a study on Alaskan malamute and German shepherd to analysed a triplet of platelet fatty acids (linoleic acid; palmitic acid; arachidonic acid)...

Intra and inter-cellular calcium signaling is present in all types of cells and body tissues. In the human brain, calcium currents and waves are related to mental activities, including emotions. We present a theoretical interpretation of these phenomena suggesting their involvement in chronic emotional patterns and in the pathology of cancer. Recent developments on biophysics, translational biology and psychoneuroendocrinoimmunology (PNEI) can support explanatory hypotheses about the link between emotional stresses and the origin and development of different types of tumor cells...

The appearing of world is approached via the dream world which has generally been thought to be merely derivative: a "composition" of memory traces from waking life, which are merged and fused into a dream world that in some instances can be indiscernable from the world of waking life. Two dreams are presented which challenge the composition theory of dream formation. An alternative unified theory of world appearance in both waking and dreaming is proposed, which makes use of developments in quantum brain dynamics...
