A novel noninvasive brain–computer interface by imagining isometric force levels

Towards a unifying model of neural net activity in the visual cortex
Cognitive Neurodynamics - Tập 1 - Trang 15-25 - 2006
A neural net model describing the non-linear interactions between axonal spikes is presented. It reconciles aspects of pattern recognition (as action of an associative memory) with those of spike synchronization and phase locking. The stability of the synchronized state is studied in detail.
Correction to: Optimized adaptive neuro-fuzzy inference system based on hybrid grey wolf-bat algorithm for schizophrenia recognition from EEG signals

Towards new concepts for a biological neuroscience of consciousness
Cognitive Neurodynamics - Tập 15 - Trang 783-804 - 2021
In the search for a sound model of consciousness, we aim at introducing new concepts: closure, compositionality, biobranes and autobranes. This is important to overcome reductionism and to bring life back into the neuroscience of consciousness. Using these definitions, we conjecture that consciousness co-arises with the non-trivial composition of biological closure in the form of biobranes and aut......
Correction to: Prediction of numbers of the accumulative confirmed patients (NACP) and the plateau phase of 2019-nCoV in China
Cognitive Neurodynamics - Tập 15 - Trang 741-741 - 2020
The article “Prediction of numbers of the accumulative confirmed patients (NACP) and the plateau phase of 2019-nCoV in China”, written by Lijun Pei was originally published Online First without Open Access.
Black-white hole pattern: an investigation on the automated chronic neuropathic pain detection using EEG signals
Cognitive Neurodynamics - - 2024
Electroencephalography (EEG) signals provide information about the brain activities, this study bridges neuroscience and machine learning by introducing an astronomy-inspired feature extraction model. In this work, we developed a novel feature extraction function, black-white hole pattern (BWHPat) which dynamically selects the most suitable pattern from 14 options. We developed BWHPat in a four-ph......
Dependency analysis of frequency and strength of gamma oscillations on input difference between excitatory and inhibitory neurons
Cognitive Neurodynamics - Tập 15 - Trang 501-515 - 2020
It has been found that gamma oscillations and the oscillation frequencies are regulated by the properties of external stimuli in many biology experimental researches. To unveil the underlying mechanism, firstly, we reproduced the experimental observations in an excitatory/inhibitory (E/I) neuronal network that the oscillation became stronger and moved to a higher frequency band (gamma band) with t......
Atypical temporal-scale-specific fractal changes in Alzheimer’s disease EEG and their relevance to cognitive decline
Cognitive Neurodynamics - Tập 13 - Trang 1-11 - 2018
Recent advances in nonlinear analytic methods for electroencephalography have clarified the reduced complexity of spatiotemporal dynamics in brain activity observed in Alzheimer’s disease (AD). However, there are far fewer studies exploring temporal scale dependent fractal properties in AD, despite the importance of studying the dynamics of brain activity within physiologically relevant frequency ......
A Kalman filtering approach to the representation of kinematic quantities by the hippocampal-entorhinal complex
Cognitive Neurodynamics - Tập 4 - Trang 315-335 - 2010
Several regions of the brain which represent kinematic quantities are grouped under a single state-estimator framework. A theoretic effort is made to predict the activity of each cell population as a function of time using a simple state estimator (the Kalman filter). Three brain regions are considered in detail: the parietal cortex (reaching cells), the hippocampus (place cells and head-direction......
Multiple time delay induced Hopf bifurcation of a cortex - basal ganglia model for Parkinson’s Disease
Cognitive Neurodynamics - - 2024
Exploring the origin of beta - band oscillation in the cortex - basal ganglia model plays an important role in understanding the mechanism of Parkinson’s disease. In this paper, we investigate the effect of three synaptic transmission time delays in the subthalamic nucleus(STN) - the globus pallidus external segment(GPe) loop, the excitatory neurons in the cortex(EXN) - the inhibitory neurons in t......
