Thalamic circuits and their contribution to the mechanisms of learning:
Currently selecting candidates to join the lab from January 2019. Multiple openings (undergraduate, graduate, postdoctoral) with flexible start dates from January. Join us now and be part of the founding projects of the lab!
Our goal is to figure out how the interactions between the cellular networks of the limbic thalamus underlie complex processes like the retrieval of memory, its use in learning, or the modulation of learning and memory by internal states (emotion, sleep).
We will rely heavily on state-of-the-art electrophysiology (units, LFPs) in behaving rats, in vivo calcium and voltage imaging, as well as optogenetics and statistical modelling.
