Generalized types of synchronization in networks of spiking neurons

Spiking Patterns of Hodgkin-Huxley Model in Alzheimer’s Disease: Effects Caused by Noise Current

In this paper we study the effect of noise on HH Model. Small-world, regular and random neural networks are the types of HH neuronal networks, which we study in spiking synchronization. External noise and Sub threshold stimulus are subjected to all the neurons. In neuronal membranes we study biophysically realistic HH neurons with intensity of intrinsic noise via voltage gated ion channels. The...

Generalized Types of Syn hronization in Networks of Spiking Neurons

Improving the Izhikevich Model Based on Rat Basolateral Amygdala and Hippocampus Neurons, and Recognizing Their Possible Firing Patterns

Introduction: Identifying the potential firing patterns following different brain regions under normal and abnormal conditions increases our understanding of events at the level of neural interactions in the brain. Furthermore, it is important to be capable of modeling the potential neural activities to build precise artificial neural networks. The Izhikevich model is one of the simplest biolog...

Towards a theory of cortical columns: From spiking neurons to interacting neural populations of finite size

Neural population equations such as neural mass or field models are widely used to study brain activity on a large scale. However, the relation of these models to the properties of single neurons is unclear. Here we derive an equation for several interacting populations at the mesoscopic scale starting from a microscopic model of randomly connected generalized integrate-and-fire neuron models. ...

A theoretical view on Dopamine Modulation

Dopamine modulation is taken as a test case for the possible function of 'slow' synapses of single neurons. We discuss possible innuences on diierent receptor types on computational properties of single neurons. Furthermore implications for networks of spiking neurons concerning temporal synchronization processes are also discussed.
