Adaptive Fuzzy Clustering Neural Network
Due to the localization of the objective function of traditional fuzzy clustering algorithm, a novel adaptive objective function of fuzzy clustering is proposed, the new objective function integrates the clust...

Kernel Granger Causality Map** Effective Connectivity: A Resting fMRI Study
The human brain is a complex, dynamic, nonlinear system and operates far from equilibrium. The functionally connected of human brain being potentially dynamic and directional, may not be adequately captured by...

Dynamics Analysis of the Hyperpolarized Model for Bursting Calcium Oscillations in Non-excitable Cells
In this paper the hyperpolarized model for bursting calcium oscillations in non-excitable cells is considered. Compared with the model without hyperpolarizing current, different bursting types of oscillation a...

Category Inference and Prefrontal Cortex
We hypothesize that the prefrontal cortex is involved in category inference. To test this hypothesis, we recorded single-unit activity from the lateral prefrontal cortex (LPFC) of two monkeys performing a sequ...

ICA Analysis for Decision-Making Task on fMRI
Brain functional activation of decision-making on fMRI experiment is seldom analyzed by data driven method to reveal the distinct brain functional network of decision-making. In this paper, a spatial independe...

Numerical Analysis of Parkinson’s Disease in a Basal Ganglia Network Model
The paper constructed a network of basal ganglia and considered the normal state, Parkinson Disease (PD) state and Deep Brain Stimulation (DBS) therapy in this basal ganglia (BG) model. The membrane potential ...

Bursting synchronization dynamics of pancreatic β-cells with electrical and chemical coupling
Based on bifurcation analysis, the synchronization behaviors of two identical pancreatic β-cells connected by electrical and chemical coupling are investigated, respectively. Various firing patterns are produc...

Estimating causal interaction between prefrontal cortex and striatum by transfer entropy
Transfer entropy (TE) is an information-theoretic measure for the investigation of causal interaction between two systems without a requirement of pre-specific interaction model (such as: linear or nonlinear)....

Noise-induced spatiotemporal patterns in Hodgkin–Huxley neuronal network
The effect of noise on the pattern selection in a regular network of Hodgkin–Huxley neurons is investigated, and the transition of pattern in the network is measured from subexcitable to excitable media. Exten...

Predictive modeling of human operator cognitive state via sparse and robust support vector machines
The accurate prediction of the temporal variations in human operator cognitive state (HCS) is of great practical importance in many real-world safety-critical situations. However, since the relationship betwee...

A comparison study of two P300 speller paradigms for brain–computer interface
In this paper, a comparison of two existing P300 spellers is conducted. In the first speller, the visual stimuli of characters are presented in a single character (SC) paradigm and each button corresponding to...

Visual pattern discrimination by population retinal ganglion cells’ activities during natural movie stimulation
In the visual system, neurons often fire in synchrony, and it is believed that synchronous activities of group neurons are more efficient than single cell response in transmitting neural signals to down-stream...

Exploring Dynamic Temporal-Topological Structure of Brain Network Within ADHD
The brain is a complex network with an anatomical and functional organization. The brain organization of attention-deficit/hyperactivity disorder (ADHD) is still not well understood. We used complex network metho...

Reward Prediction in Prefrontal Cortex and Striatum
The prefrontal cortex (PFC) and striatum have mutual connections through direct and indirect pathways, and both are involved in reward prediction. But it has been suggested that the PFC and striatum may have d...

EEG oscillations reflect task effects for the change detection in vocal emotion
How task focus affects recognition of change in vocal emotion remains in debate. In this study, we investigated the role of task focus for change detection in emotional prosody by measuring changes in event-re...

A Review of Gait Movement Under Visual Perception Neural Code
The research on neural code theory of gait movement under visual perception has important significance for understanding brain working mechanisms of sensory input, cognitive process or motor output, and for fu...

Causal Interaction Between Prefrontal Cortex and Striatum Estimated by Granger Causality
The prefrontal cortex (PFC) and the striatum have mutual connections through direct and indirect pathways. It is known that neurons in the two areas encode reward information. However, it remains elusive that ...

Reward-Modulated Functional Connectivity Between Prefrontal Cortex and Striatum
Functional connectivity between the prefrontal cortex (PFC) and striatum is thought to be critical in cognitive processing. Local field potentials (LFPs) were simultaneously recorded in the lateral PFC and str...

Integration of Facial and Vocal Cues in the Perception of Bimodal Emotion Changes
How emotion changes in vocal and facial modalities integrate into a unified percept has yet to be investigated. We tested this question by recording electroencephalogram (EEG) while participants detect vocal o...
