Towards a unifying model of neural net activity in the visual cortex
Cognitive Neurodynamics - Tập 1 - Trang 15-25 - 2006
Hermann Haken
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.
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
Xiaochun Gu, Fang Han, Zhijie Wang
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...... hiện toàn bộ
A Kalman filtering approach to the representation of kinematic quantities by the hippocampal-entorhinal complex
Cognitive Neurodynamics - Tập 4 - Trang 315-335 - 2010
Graham Wordsworth Osborn
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...... hiện toàn bộ
Multiple time delay induced Hopf bifurcation of a cortex - basal ganglia model for Parkinson’s Disease
Cognitive Neurodynamics - - 2024
Qiaohu Zhang, Quansheng Liu, Yuanhong Bi
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...... hiện toàn bộ
Pruning and quantization algorithm with applications in memristor-based convolutional neural network
Cognitive Neurodynamics - - Trang 1-13 - 2023
Mei Guo, Yurui Sun, Yongliang Zhu, Mingqiao Han, Gang Dou, Shiping Wen
The human brain’s ultra-low power consumption and highly parallel computational capabilities can be accomplished by memristor-based convolutional neural networks. However, with the rapid development of memristor-based convolutional neural networks in various fields, more complex applications and heavier computations lead to the need for a large number of memristors, which makes power consumption i...... hiện toàn bộ
Effectual seizure detection using MBBF-GPSO with CNN network
Cognitive Neurodynamics - - Trang 1-12 - 2023
Dinesh Kumar Atal, Mukhtiar Singh
EEG is the most common test for diagnosing a seizure, where it presents information about the electrical activity of the brain. Automatic Seizure detection is one of the challenging tasks due to limitations of conventional methods with regard to inefficient feature selection, increased computational complexity and time and less accuracy. The situation calls for a practical framework to achieve bet...... hiện toàn bộ
Correction to: Bacomics: a comprehensive cross area originating in the studies of various brain–apparatus conversations
Cognitive Neurodynamics - Tập 17 Số 3 - Trang 813-813 - 2023
Yao, Dezhong, Zhang, Yangsong, Liu, Tiejun, Xu, Peng, Gong, Diankun, Lu, Jing, Xia, Yang, Luo, Cheng, Guo, Daqing, Dong, Li, Lai, Yongxiu, Chen, Ke, Li, Jianfu
Category representation in primary visual cortex after visual perceptual learning
Cognitive Neurodynamics - - Trang 1-13 - 2023
Zhaofan Liu, Yin Yan, Da-Hui Wang
The visual perceptual learning (VPL) leads to long-term enhancement of visual task performance. The subjects are often trained to link different visual stimuli to several options, such as the widely used two-alternative forced choice (2AFC) task, which involves an implicit categorical decision. The enhancement of performance has been related to the specific changes of neural activities, but few st...... hiện toàn bộ
Ionic channel blockage in stochastic Hodgkin–Huxley neuronal model driven by multiple oscillatory signals
Cognitive Neurodynamics - Tập 14 - Trang 569-578 - 2020
Xiuying Zhou, Ying Xu, Guowei Wang, Ya Jia
Ionic channel blockage and multiple oscillatory signals play an important role in the dynamical response of pulse sequences. The effects of ionic channel blockage and ionic channel noise on the discharge behaviors are studied in Hodgkin–Huxley neuronal model with multiple oscillatory signals. It is found that bifurcation points of spontaneous discharge are altered through tuning the amplitude of m...... hiện toàn bộ
