Towards a learning-theoretic analysis of spike-timing dependent plasticity
dependent plasticity learning-theoretic analysis spike-timing
2012/11/26
This paper suggests a learning-theoretic perspective on how synaptic plasticity benefits global brain functioning. We introduce a model, the selectron, that (i) arises as the fast time constant limit ...
Quantifying impacts of short-term plasticity on neuronal information transfer

2012/4/28
Short-term changes in efficacy have been postulated to enhance the ability of synapses to transmit information between neurons, and within neuronal networks. Even at the level of connections between s...
Control over stress induces plasticity of individual prefrontal cortical neurons: A conductance-based neural simulation
Control over stress plasticity of individual prefrontal cortical neurons conductance-based neural simulation Neurons and Cognition

Behavioral control over stressful stimuli induces resilience to future conditions when control is lacking. The medial prefrontal cortex(mPFC) is a critically important brain region required for plasti...

May 21, 2007，Scientists are keenly studying how neurons form synapses--the physical and chemical connections between neurons--and the "pruning" of neural circuits during development, not least because...
