Parallel pathways from whisker and visual sensory cortices to distinct frontal regions of mouse neocortex

Carl Petersen, Varun Sreenivasan, Céline Matéo, Alexandros Kyriakatos

The spatial organization of mouse frontal cortex is poorly understood. Here, we used voltage-sensitive dye to image electrical activity in the dorsal cortex of awake head-restrained mice. Whisker-deflection evoked the earliest sensory response in a localiz ...

In Vivo Optogenetic Stimulation of Neocortical Excitatory Neurons Drives Brain-State-Dependent Inhibition

Carl Petersen, Céline Matéo, Michael Avermann

Background: Synaptic interactions between excitatory and inhibitory neocortical neurons are important for mammalian sensory perception. Synaptic transmission between identified neurons within neocortical microcircuits has mainly been studied in brain slice ...

Optogenetic Probing of Cortical Synaptic Circuits Measured Through in Vivo Whole-Cell Recordings in the Mouse Barrel Cortex

Céline Matéo

Although neocortex underlies higher-order brain functions, little is known about the synaptic interactions that drive neocortical microcircuit function in vivo. The neocortex is spontaneously active in vivo so I explored how such spontaneous network activi ...

Long-range connectivity of mouse primary somatosensory barrel cortex

Bernard Schneider, Carl Petersen, Rachel Aronoff, Céline Matéo, Ferenc Mátyás

The primary somatosensory barrel cortex processes tactile vibrissae information, allowing rodents to actively perceive spatial and textural features of their immediate surroundings. Each whisker on the snout is individually represented in the neocortex by ...

Motor control by sensory cortex

Carl Petersen, Varun Sreenivasan, Rachel Aronoff, Céline Matéo, Ferenc Mátyás, Fred Marbach, Catherine Wacongne

Classical studies of mammalian movement control define a prominent role for the primary motor cortex. Investigating the mouse whisker system, we found an additional and equally direct pathway for cortical motor control driven by the primary somatosensory c ...
