Fear Learning: An Evolving Picture for Plasticity at Synaptic Afferents to the Amygdala

Ralf Schneggenburger, Denys Osypenko, Shriya Palchaudhuri

Unraveling the neuronal mechanisms of fear learning might allow neuroscientists to make links between a learned behavior and the underlying plasticity at specific synaptic connections. In fear learning, an innocuous sensory event such as a tone (called the ...

Cortical and subcortical changes in resting-state neuronal activity and connectivity in early symptomatic ALS and advanced frontotemporal dementia

Alessandra Griffa

The objective of this study was to examine if patterns of resting-state brain activity and functional connectivity in cortical and subcortical regions in patients with early symptomatic amyotrophic lateral sclerosis (ALS) resemble those of behavioural vari ...

Olfactory modulation of barrel cortex activity during active whisking and passive whisker stimulation

Anthony Pierre Robert Renard

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 ...

Cortical ensembles orchestrate social competition through hypothalamic outputs

Hao Li

Most social species self-organize into dominance hierarchies(1,2), which decreases aggression and conserves energy(3,4), but it is not clear how individuals know their social rank. We have only begun to learn how the brain represents social rank(5-9) and g ...

The role of pre-stimulus alpha rhythms in non-retinotopic feature integration

Michael Herzog, David Pascucci, Maëlan Quentin Menétrey

What is the link between spontaneous neuronal oscillations (i.e., non-evoked activity) and perception? Often, the phase or power of alpha activity is proposed to modulate perception. The majority of work has focused on the unecological presentation of sing ...

Revisiting brain rewiring and plasticity in children born without corpus callosum

Dimitri Nestor Alice Van De Ville, Maria Giulia Preti, Vanessa Siffredi, Silvia Obertino

The corpus callosum is the largest white matter pathway connecting homologous structures of the two cerebral hemispheres. Remarkably, children and adults with developmental absence of the corpus callosum (callosal dysgenesis, CD) show typical interhemisphe ...

Anatomical and functional characterization of neocortical circuits involved in transforming whisker sensory processing into goal-directed licking

Georgios Foustoukos

The choice of an action upon perception of an external stimulus, arriving at a sensory organ of an animal, depends on previous experiences and outcomes throughout its life. In the rodent brain, the underlying mechanisms involved in simple sensorimotor tran ...

Large-scale functional network dynamics in human callosal agenesis: Increased subcortical involvement and preserved laterality

Dimitri Nestor Alice Van De Ville, Vanessa Siffredi, Anjali Bagunu Tarun, Younes Farouj

In the human brain, the corpus callosum is the major white-matter commissural tract enabling the transmission of sensory-motor, and higher level cognitive information between homotopic regions of the two cerebral hemispheres. Despite developmental absence ...

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, Yanqi Liu, Georgios Foustoukos, Samuel Pavio Muscinelli, Keita Tamura, Anastasiia Oryshchuk, Marta Boscaglia

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 ...

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 ...
