Neuron Models and Stochastic Processes

The lecture explores the concept of stochastic intensity in neuronal dynamics, focusing on inter spike interval distribution and survival functions. It discusses the application of renewal theory and the translation of continuous time escape rates into discrete time probabilities. The lecture also covers experimental applications and the intrinsic noise sources in neurons, providing a foundation for future studies on spike train likelihood and neuron model fitting.
