Ensemble recordings in the somatosensory system of the rat after learning of a discrimination task

This project concerns the thalamocortical integration of tactile stimuli in the rat. We developed an active vibrissal task in a T-like maze, in which rats have to palpate code-bar-like textures with their whiskers in order to choose a reward site among two. Multi-electrode implantation in the barrel cortex and the thalamus allows us to examine the spiking activity of a large population of neurons, in the anesthetized animal after learning. We aim to identify unique spike patterns coding for the particular stimuli used in the discrimination task. The student will be involved in the acute recordings and in the analysis of electrophysiological signals.
