Department: CIN Systems Neurophysiology

Position: Head of Research Group

Scientific topic: Systems Neurophysiology, Behavioral Neurophysiology


Field of Research

Our main interest is how the activity of single neurons and small neuron networks relate to behavior. We work on questions how top-down signals modulate sensory processing and affect perception (active perception). Candidate top-down signals are those related to movements that serve sensation and presumably improve perception. In future studies we will study if and how executive signals generated in the prefrontal cortex act on the sensorimotor loop to improve perception and/or prepare movements.

Methods

Our model system is whisker-based tactile perception in rodents. These animals use delibaretely tuned whisker movements to scan their tactile environment. Currently we apply multi neuron, multi-electrode extracellular electrophysiology in awake behaviorally trained rodents.
