Tutorial and colloquium on Dynamical Systems Ideas in Application Series with Lai-Sang Young (CIMS, NYU) 


In the first session, I will introduce some relevant concepts in theoretical neuroscience, and take some time to familiarize the audience with the dynamics of a population of integrate-and-fire neurons. This is strictly introductory material; no prior exposure to neuroscience is assumed. In the second session, I will report on some ongoing computational modeling work. We seek to model the monkey visual cortex, which is very similar to our own, as a large and complex dynamical system. In this talk, I will focus on how visual signals are passed from the lateral geniculate nuclei (LGN) to the input layer of the primary visual cortex (V1). I will discuss what anatomical information can be gleaned from biology, how it is used to build a mathematical model, the experimental data used for validation, the analysis of dynamical mechanisms, and finally, what we have learned from this modeling work so far. This is joint work with Robert Shapley (Center for Neural Science, NYU) and Logan Chariker (PhD student, Courant)
