MM-CA4(b)-S2 Neurophysiologie cognitive de la perception

Course content:

The aim of this UE is to introduce the audience with classical and cutting edge research articles focusing on the neurophysiology of decision-making. We will focus on the interplay between bottom-up and top-down factors during the selection of relevant information. The emphasis will be on electrophysiological recordings across multiple areas (from sensory to frontal cortices) in behaving animals. Each week a student will present one paper from a set of articles proposed in advance. Questions and discussion during and after the presentation will be encouraged.

Intended Audience:

• students within the Cogmaster program
• students with a quantitative background (physics, computer science, mathematics, engineering etc.) that are interested in neuroscience
• students with a biology/neuroscience background that are interested in quantitative (mathematical) approaches to neuroscience


Each week will be dedicated to one research article (see choice of articles below; please write to boubenec at ens dot fr to get a copy of these articles). This article will be presented by a student in a short talk (about 30 minutes), followed by a discussion among the students. To ensure a lively discussion, every student has to read the article and submit a question about it one week in advance. Students in the course will be judged by the talk they give (50%) and their participation in the discussions of all the other talks (50%).

Course Language:
The course languages will be French and English. Talks can be held in either language.

Tuesday 10h30-12h30 (07/03 → 30/06) / salle Théodule Ribot (29 rue d'Ulm)
