Distinct Contributions of Whisker Sensory Cortex and Tongue-Jaw Motor Cortex in a Goal-Directed Sensorimotor Transformation

Carl Petersen, Georgios Foustoukos, Matthieu Pierre Auffret, Keita Tamura, Johannes Maria Mayrhofer, Sami El-Boustani

The neural circuits underlying goal-directed sensorimotor transformations in the mammalian brain are incompletely understood. Here, we compared the role of primary tongue-jaw motor cortex (tjM1) and primary whisker sensory cortex (wS1) in head-restrained m ...

Optogenetic Peripheral Nerve Immunogenicity

Optogenetic technologies have been the subject of great excitement within the scientific community for their ability to demystify complex neurophysiological pathways in the central (CNS) and peripheral nervous systems (PNS). The excitement surrounding opto ...

Optical sensory and motor mapping of mouse dorsal cortex

Matthieu Pierre Auffret

Throughout species, including mice and humans, we all have to make decisions to fulfill our fundamentals needs: eat, drink, explore, communicate, reproduce... To make those decisions, we have to collect informations from the surrounding world and to proces ...

Optical cuff for optogenetic control of the peripheral nervous system

Stéphanie Lacour, Grégoire Courtine, Léonie Asboth, Frédéric Pierre Gérald Michoud

Objective. Nerves in the peripheral nervous system (PNS) contain axons with specific motor, somatosensory and autonomic functions. Optogenetics offers an efficient approach to selectively activate axons within the nerve. However, the heterogeneous nature o ...

The dopaminergic VTA - basal amygdala projection contributes to signal aversive state in fear memory

Wei Tang

Dopamine released from midbrain neurons is an important neuromodulatory signal during associative learning in many forebrain circuits. One model of associative learning is auditory cued fear learning, during which an innocuous sensory percept like a tone ( ...

Specific synaptic input strengths determine the computational properties of excitation-inhibition integration in a sound localization circuit

Ralf Schneggenburger, Friedemann Zenke, Enida Gjoni, Brice Antoine Alexandre Bouhours

The lateral superior olive (LSO) is a binaural nucleus in the auditory brainstem in which excitation from the ipsilateral ear is integrated with inhibition from the contralateral ear. It is unknown whether the strength of the unitary inhibitory and excitat ...

Structural and functional brain imaging using extended-focus optical coherence tomography and microscopy

Paul James Marchand

Neuroimaging techniques aim at revealing the anatomy and functional organisation of cerebral structures. Over the past decades, functional magnetic resonance imaging (fMRI) has revolutionized our understanding of human cerebral physiology through its abili ...

Layer, cell-type and pathway-specific thalamocortical input to mouse somatosensory cortex

Berat Semihcan Sermet

In the mouse whisker system, sensory information is relayed to the whisker somatosensory cortex by two major thalamic nuclei, the ventral posterior medial nucleus (VPM) and the posterior medial nucleus (POM). While the cortical axonal innervation pattern o ...

A Robotic System for Adaptive Training and Function Assessment of Forelimb Retraction in Mice

Silvestro Micera

Rodent models are decisive for translational research in healthy and pathological conditions of motor function thanks to specific similarities with humans. Here, we present an upgraded version of the M-Platform, a robotic device previously designed to trai ...

Whole-Cell Recording of Neuronal Membrane Potential during Behavior

Carl Petersen

Neuronal membrane potential is of fundamental importance for the mechanistic understanding of brain function. This review discusses progress in whole-cell patch-clamp recordings for low-noise measurement of neuronal membrane potential in awake behaving ani ...
