Cell-class-specific orofacial motor maps in mouse neocortex

Léa Marie Veaute, Hidenobu Mizuno, Carl Petersen, Sylvain Crochet, Keita Tamura, Pol Bech Vilaseca

Cortical motor maps represent fundamental organizing principles for voluntary motor control,1 yet their underlying structure remains poorly understood, including regions of sensory2,3 and parietal cortex,4 as well as the classical frontal motor cortex. To ...

Learning-related congruent and incongruent changes of excitation and inhibition in distinct cortical areas

Carl Petersen, Sylvain Crochet, Romain Guiet, Georgios Foustoukos, Vahid Esmaeili, Yanqi Liu, Keita Tamura, Anastasiia Oryshchuk

Excitatory and inhibitory neurons in diverse cortical regions are likely to contribute differentially to the transformation of sensory information into goal-directed motor plans. Here, we investigate the relative changes across mouse sensorimotor cortex in ...

Rapid suppression and sustained activation of distinct cortical regions for a delayed sensory-triggered motor response

Wulfram Gerstner, Carl Petersen, Sylvain Crochet, Alireza Modirshanechi, Vahid Esmaeili, Samuel Pavio Muscinelli, Georgios Foustoukos, Keita Tamura, Yanqi Liu, Anastasiia Oryshchuk

The neuronal mechanisms generating a delayed motor response initiated by a sensory cue remain elusive. Here, we tracked the precise sequence of cortical activity in mice transforming a brief whisker stimulus into delayed licking using wide-field calcium im ...

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 ...

Cell class-specific long-range axonal projections of neurons in mouse whisker-related somatosensory cortices

Lucas Téo Délez, Carl Petersen, Sylvain Crochet, Keita Tamura, Yanqi Liu, Pol Bech Vilaseca

Long-range axonal projections of diverse classes of neocortical excitatory neurons likely contribute to brain-wide interactions processing sensory, cognitive and motor signals. Here, we performed light-sheet imaging of fluorescently labeled axons from gene ...

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, ...
