Oscillations and synchrony in a cortical neural network [PDF]

Cognitive Neurodynamics, 2013
In this paper, the oscillations and synchronization status of two different network connectivity patterns based on Izhikevich model are studied. One of the connectivity patterns is a randomly connected neuronal network, the other one is a small-world neuronal network.

Synchrony in Excitatory Neural Networks

Neural Computation, 1995
Synchronization properties of fully connected networks of identical oscillatory neurons are studied, assuming purely excitatory interactions. We analyze their dependence on the time course of the synaptic interaction and on the response of the neurons to small depolarizations. Two types of responses are distinguished. In the first type, neurons always

Potential Mechanisms and Functions of Intermittent Neural Synchronization

Frontiers in Computational Neuroscience, 2017
Neural synchronization is believed to play an important role in different brain functions. Synchrony in cortical and subcortical circuits is frequently variable in time and not perfect.

A Narrative Review Examining the Utility of Interpersonal Synchrony for the Caregiver-Care Recipient Relationship in Alzheimer’s Disease and Related Dementias

Frontiers in Psychology, 2021
The stressful nature of caring for an older adult with a chronic disease, such as Alzheimer’s disease (AD), can create barriers between the caregiver-care recipient, as they try to navigate their continuously changing social relationship.

Synchrony Can Destabilize Reward-Sensitive Networks

Frontiers in Neural Circuits, 2014
When exposed to rewarding stimuli, only some animals develop persistent craving. Others are resilient and do not. How the activity of neural populations relates to the development of persistent craving behavior is not fully understood.

Patterns of Synchrony in Neural Networks with Spike Adaptation [PDF]

Neural Computation, 2001
We study the emergence of synchronized burst activity in networks of neurons with spike adaptation. We show that networks of tonically firing adapting excitatory neurons can evolve to a state where the neurons burst in a synchronized manner. The mechanism leading to this burst activity is analyzed in a network of integrate-and-fire neurons with spike ...

Sixty hertz neurostimulation amplifies subthalamic neural synchrony in Parkinson's disease. [PDF]

PLoS ONE, 2015
High frequency subthalamic nucleus (STN) deep brain stimulation (DBS) improves the cardinal motor signs of Parkinson's disease (PD) and attenuates STN alpha/beta band neural synchrony in a voltage-dependent manner.

Synchrony Between Sensory and Cognitive Networks is Associated with Subclinical Variation in Autistic Traits

Frontiers in Human Neuroscience, 2015
Individuals with autistic spectrum disorders exhibit distinct personality traits linked to attentional, social, and affective functions, and those traits are expressed with varying levels of severity in the neurotypical and subclinical population ...

Neurophysiological trajectories in Alzheimer’s disease progression

eLife
Alzheimer’s disease (AD) is characterized by the accumulation of amyloid-β and misfolded tau proteins causing synaptic dysfunction, and progressive neurodegeneration and cognitive decline.
