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

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 ...

Devices, systems and methods for dispensing and analysing particles

Philippe Renaud, Yann Barrandon, David Vincent Bonzon, Jean-Baptiste Bureau, Steve Béguin

The present invention relates to a pipette tip comprising a thin holed membrane at its distal end, which is designed to be adapted with a system comprising at least an impedance analyser and a fluidic actuator to perform the dispensing and analysis of part ...

Movement Initiation Signals in Mouse Whisker Motor Cortex

Carl Petersen, Sylvain Crochet, Varun Sreenivasan, Taro Kiritani, Katia Galan, Vahid Esmaeili

Frontal cortex plays a central role in the control of voluntary movements, which are typically guided by sensory input. Here, we investigate the function of mouse whisker primary motor cortex (wM1), a frontal region defined by dense innervation from whiske ...

Motor Control in the Mouse Whisker System

Varun Sreenivasan

The motor systems of the mammalian brain are a remarkable product of many millions of years of evolution. It is the motor systems that make us and other mammals mobile, that guide our actions in response to sensory information and conversely modulate the v ...

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 ...

Spice Simulation of Substrate Minority Carriers Propagation with Equivalent Electrical Circuit

Maher Kayal, Jean-Michel Sallese, Pietro Buccella, Camillo Stefanucci

This paper presents an equivalent electrical circuit for one dimensional substrate minority carriers spice simulation. The electrical circuit parameters are extracted from substrate meshing applying the finite difference method. This model is derived from ...

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 ...

Synaptic Mechanisms Underlying Sparse Coding of Active Touch

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

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 ...

Model to predict overheating risk based on an electrical capacitor analogy

Darren Robinson, Frédéric Haldi

It is important for building designers to be able to judge if a space is likely to overheat, whether to determine if HVAC plant is required or to design this out by passive means. To this end several overheating risk criteria have recently been published. ...
