Competences

The cours aims at giving an advanced and rigorous Introduction to Neurobiology. I will link the biophysical mechanisms of electrical excitability and of synaptic transmission, to the detailed description of synaptic plasticity and of the cellular and molecular basis of memories in the brain. The course is based on experiments and all statements will be grounded on an experimental basis.

Prerequisites

General and basic knowledge of molecular and cell biology and of physiology. Students of other disciplines are most welcome and any requirement of previpus knowledge can be discussed individually.
