PhD Program: course in Computational Neuroscience

Context

Computational neuroscience is an expending field that is proving to be essential in neurosciences. The aim of this course will be to provide a common solid background in computational neurosciences. The course will comprise historical recall of the field and a description of the different modelling approaches that are currently developed, including details about their specificities, limits and advantages.

Objective

The course aims at introducing students with the major tools that will be necessary during their thesis to model or analyze their neuroscientific results. While it will start by a short, generic introduction, we will then explore different systems at different scales. On the first day, we will study the different possible regimes in which a single neuron can behave, while progressively introducing the theory of dynamical systems to understand these more globally. Then, during the second day, we will introduce methods to analyze neuroscientific data in general, such as Bayesian methods and information theory. This will be implemented by simple practical examples.

~20 hours (session 1=7 + session 2=7 + session 3=4)

Max participants

15 for the practical sessions (afternoon Day 2 and Day 3), unlimited for theoretical courses

Public priority

PhD students

Public concerned

PhD students, interested M2 students and postdocs

Location

Institut des Neurosciences de la Timone (INT)

Keywords

neuronal modelling, neural circuit modelling, information theory, decoding and encoding

Targets

Understanding how computational modelling can be used to formulate and solve neuroscience problems at different spatial and temporal scales; learning the formal notions of information, encoding and decoding and experimenting their use on toy datasets

Program

First session: Introduction to modeling single neurons (morning); An introduction to neural masses: modeling assemblies of neurons up to capturing collective oscillations and resting state dynamics in a mean-field model - presentation of the Virtual Brain software (afternoon) - Second session: An overview on “What is encoding?” “What is decoding?”: formalization of the notion of information in neural activity; shared and transferred information; integration, segregation and complexity (morning). Bayesian probabilities, the Free-energy principle and Active Inference, with practical demonstrations in python (afternoon). Third session: the problem of information estimation in practice. Practical exercices in Matlab: estimating entropy and stimulus decodability from spike trains; comparing coding hypotheses (morning).

Pre-required

Basic knowledge of statistics and probability and calculus (differential equations,…) is useful, but steps will be explained and complex math avoided as much as possible. Practical exercises are in python and/or MATLAB, so basic knowledge of these environments is a plus.
