Contenus de l'unité d'enseignement

The course is an introduction to the dynamics of excitable systems, with a particular focus on neuronal excitability at the cellular and network levels.

The course will cover basic dynamical properties of neurons, which include

• Excitability and spiking activity
• Type I and Type II excitability
• Rest-spike bistability
• Bursting

• Dendritic and axonal propagation
• Models of synapse
• Population dynamics : rates models, neural mass models, neural fields models
• Possible applications: decision making, associative memory, learning, visual hallucinations, wake-sleep cycle...

• stability of equilibria and limit cycles
• phase portrait analysis
• bifurcations of fixed points and limit cycles
• singularities
• space-time behaviour, space-time pattern formation
• etc.

Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement

At the end of this course, the student will have a good understanding of the mechanisms underlying neuronal dynamics and neuromodulation. He/she will master the mathematical concepts and techniques required to study these dynamics: phase portrait analysis, trajectory simulation, fixed point computation, stability analysis, bifurcation diagrams, space-time behaviour, etc. In addition, the student will be able to use the relevant tools on computer (Julia).

Activités d'apprentissage prévues et méthodes d'enseignement

For the first part of the course on cellular dynamics, the course is based on 2h tutorials on Julia notebooks followed by 2h ex-cathedra lectures on theoretical concepts. Active student participation is required during the tutorials. The second part on populations dynamics will consists in ex-cathedra lectures and a project (report on a scientific paper, with associated computer modelling).

Explications complémentaires:

Julia notebooks will be evaluated throughout the year; the project report is evaluated only in the first session (the mark obtained is automatically transferred to the second session); a written exam is organised during both sessions. (Note that the timely submission of the reports associated with the hands-on work is a condition for participating in the written examination.)
