Cholinergic Signals in Mouse Barrel Cortex during Active Whisker Sensing

Carl Petersen, Sylvain Crochet, Yves Emile Alfred Kremer, Emmanuel Albert Eggermann

Internal brain states affect sensory perception, cognition, and learning. Many neocortical areas exhibit changes in the pattern and synchrony of neuronal activity during quiet versus active behaviors. Active behaviors are typically associated with desynchr ...

Membrane Potential Dynamics of Neocortical Projection Neurons Driving Target-Specific Signals

Carl Petersen, Yves Emile Alfred Kremer, Aurélie Pala, Takayuki Yamashita, Egbert Welker, Leticia Pedrido

Primary sensory cortex discriminates incoming sensory information and generates multiple processing streams toward other cortical areas. However, the underlying cellular mechanisms remain unknown. Here, by making whole-cell recordings in primary somatosens ...

Membrane potential correlates of sensory perception in mouse barrel cortex

Carl Petersen, Yves Emile Alfred Kremer, Shankar Sachidhanandam, Varun Sreenivasan, Alexandros Kyriakatos

Neocortical activity can evoke sensory percepts, but the cellular mechanisms remain poorly understood. We trained mice to detect single brief whisker stimuli and report perceived stimuli by licking to obtain a reward. Pharmacological inactivation and optog ...

Unique functional properties of somatostatin-expressing GABAergic neurons in mouse barrel cortex

Carl Petersen, Yves Emile Alfred Kremer

Neocortical GABAergic neurons have diverse molecular, structural and electrophysiological features, but the functional correlates of this diversity are largely unknown. We found unique membrane potential dynamics of somatostatin-expressing (SOM) neurons in ...

Synaptic Mechanisms Underlying Sparse Coding of Active Touch

Carl Petersen, Sylvain Crochet, Yves Emile Alfred Kremer, James Poulet

Sensory information is actively gathered by animals, but the synaptic mechanisms driving neuronal circuit function during active sensory processing are poorly understood. Here, we investigated the synaptically driven membrane potential dynamics during acti ...
