Axonal and Dendritic Morphology of Excitatory Neurons in Layer 2/3 Mouse Barrel Cortex Imaged Through Whole-Brain Two-Photon Tomography and Registered to a Digital Brain Atlas
Carl Petersen, Sylvain Crochet, Yanqi Liu, Georgios Foustoukos
Communication between cortical areas contributes importantly to sensory perception and cognition. On the millisecond time scale, information is signaled from one brain area to another by action potentials propagating across long-range axonal arborizations. ...
FRONTIERS MEDIA SA2022Olfactory modulation of barrel cortex activity during active whisking and passive whisker stimulation
Rodents depend on olfaction and touch to meet many of their fundamental needs. However, the impact of simultaneous olfactory and tactile inputs on sensory representations in the cortex remains elusive. To study these interactions, we recorded large populat ...
NATURE PORTFOLIO2022Input-dependent regulation of excitability controls dendritic maturation in somatosensory thalamocortical neurons
Johannes Gräff, Jose Vicente Sanchez Mut
Input from the sensory organs is required to pattern neurons into topographical maps during development. Dendritic complexity critically determines this patterning process; yet, how signals from the periphery act to control dendritic maturation is unclear. ...
2017Parallel 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 ...
SPIE-Intl Soc Optical Eng2017Using the Green's function to simplify and understand dendrites
Neurons are endowed with dendrites: tree-like structures that collect and transform inputs. These arborizations are believed to substantially enhance the computational repertoire of neurons. While it has long been known that dendrites are not iso-potential ...
EPFL2017Imaging the Dynamics of Neocortical Population Activity in Behaving and Freely Moving Mammals
The development of functional imaging techniques applicable to neuroscience and covering a wide range of spatial and temporal scales has greatly facilitated the exploration of the relationships between cognition, behaviour and electrical brain activity. Fo ...
Springer-Verlag Berlin2015Cholinergic 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 ...
Elsevier2014Cell-type specific function of GABAergic neurons in layers 2 and 3 of mouse barrel cortex
GABAergic neurons are a minor fraction of the neocortical neuronal population, but they are highly diverse in their features. The GABAergic neurons can be divided into three largely non-overlapping groups, defined through the expression of ionotropic serot ...
Current Biology Ltd2014High Bandwidth Synaptic Communication and Frequency Tracking in Human Neocortex
Neuronal firing, synaptic transmission, and its plasticity form the building blocks for processing and storage of information in the brain. It is unknown whether adult human synapses are more efficient in transferring information between neurons than roden ...
Public Library Science2014Direct mapping of 19F in 19FDG-6P in brain tissue at subcellular resolution using soft X-ray fluorescence
Rolf Gruetter, Carole Poitry-Yamate
Low energy x-ray fluorescence (LEXRF) detection was optimized for imaging cerebral glucose metabolism by mapping the fluorine LEXRF signal of 19 F in 19 FDG, trapped as intracellular 19 F-deoxyglucose-6-phosphate ( 19 FDG-6P) at 1μm spatial resolution from ...
