Axonal projections from mouse whisker-related sensory cortex

Yanqi Liu

Neurons primarily communicate through release of neurotransmitter from presynaptic specialisations along their axonal arborisations. In order to understand the functional role of a specific neuron, it is therefore of great interest to know the structure of ...

Modeling and simulation of rat non-barrel somatosensory cortex. Part I: Modeling anatomy

Matthias Wolf, Henry Markram, Kathryn Hess Bellwald, Felix Schürmann, Eilif Benjamin Muller, Srikanth Ramaswamy, Michael Reimann, Daniel Keller, Werner Alfons Hilda Van Geit, James Gonzalo King, Lida Kanari, Pramod Shivaji Kumbhar, Alexis Arnaudon, Ying Shi, Jean-Denis Georges Emile Courcol, Armando Romani, András Ecker, Michael Emiel Gevaert, Cyrille Pierre Henri Favreau, Vishal Sood, Sirio Bolaños Puchet, James Bryden Isbister, Judit Planas Carbonell, Daniela Egas Santander, Christoph Pokorny, Adrien Michel Achille Devresse, Gianluca Ficarelli, Hugo Thabo Dictus, Janis Lazovskis, Juan Bautista Hernando Vieites, Huanxiang Lu, Liesbeth Maria L Vanherpe, Ran Levi, Joni Henrikki Herttuainen, Samuel Lieven D. Lapere, Juan Luis Riquelme Roman, Thomas Brice Delemontex, Nicolas René Jean Ninin, Alexander Dietz, Benoît Jean-Albert Coste

The function of the neocortex is fundamentally determined by its repeating microcircuit motif, but also by its rich, hierarchical, interregional structure with a highly specific laminar architecture. The last decade has seen the emergence of extensive new ...

Neuronal Circuits In Barrel Cortex For Whisker Sensory Perception

Carl Petersen

The array of whiskers on the snout provides rodents with tactile sensory information relating to the size, shape and texture of objects in their immediate environment. Rodents can use their whiskers to detect stimuli, distinguish textures, locate objects a ...

Cortical circuits for transforming whisker sensation into goal-directed licking

Carl Petersen, Sylvain Crochet, Vahid Esmaeili, Georgios Foustoukos, Keita Tamura, Anastasiia Oryshchuk

Animals can learn to use sensory stimuli to generate motor actions in order to obtain rewards. However, the precise neuronal circuits driving learning and execution of a specific goal-directed sensory-to-motor transformation remain to be elucidated. Here, ...

Sensorimotor processing in the rodent barrel cortex

Carl Petersen

Tactile sensory information from facial whiskers provides nocturnal tunnel-dwelling rodents, including mice and rats, with important spatial and textural information about their immediate surroundings. Whiskers are moved back and forth to scan the environm ...

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

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

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 ...

Creating a neuroprosthesis for active tactile exploration of textures

Solaiman Shokur, Miguel Nicolelis

Intracortical microstimulation (ICMS) of the primary somatosensory cortex (S1) can produce percepts that mimic somatic sensation and, thus, has potential as an approach to sensorize prosthetic limbs. However, it is not known whether ICMS could recreate act ...

Two-photon calcium imaging of neocortical projection neurons in whisker somatosensory cortex during goal-directed sensorimotor learning

Dimitra Angeliki Vavladeli

Abstract Excitatory projection neurons of the neocortex are thought to play important roles in per-ceptual and cognitive functions of the brain by directly connecting diverse cortical and subcortical areas. However, many aspects of the anatomical and func ...

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 ...

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 ...
