Prefrontal engrams of long-term fear memory perpetuate pain perception

A painful episode can lead to a life-long increase in an individual's experience of pain. Fearful anticipation of imminent pain could play a role in this phenomenon, but the neurobiological underpinnings are unclear because fear can both suppress and enhan ...

Elastic and dynamic properties of membrane phase-field models

Ignacio Pagonabarraga Mora

Phase-field models have been extensively used to study interfacial phenomena, from solidification to vesicle dynamics. In this article, we analyze a phase-field model that captures the relevant physical features that characterize biological membranes. We s ...

Mechanosensory interactions drive collective behaviour in Drosophila

Dario Floreano, Pavan P Ramdya, Pawel Lichocki, Lukas Frisch, Winnie Wing Yee Tse

Collective behaviour enhances environmental sensing and decision-making in groups of animals. Experimental and theoretical investigations of schooling fish, flocking birds and human crowds have demonstrated that simple interactions between individuals can ...

Synaptic consolidation: from synapses to behavioral modeling

Wulfram Gerstner, Friedemann Zenke, Lorric Ziegler, David Barak Kastner

Synaptic plasticity, a key process for memory formation, manifests itself across different time scales ranging from a few seconds for plasticity induction up to hours or even years for consolidation and memory retention. We developed a three-layered model ...

Hyper-emotional neurophysiology in a rat model of autism

Mônica Regina Favre

Autism is a pervasive neurodevelopmental disorder of unknown etiology, characterized by a spectrum of symptoms of social impairment, abnormal communication, and unusual restricted, inflexible behaviors. Patients also frequently present various levels of se ...

Effective Stimuli for Constructing Reliable Neuron Models

Henry Markram, Sean Lewis Hill, Thomas Berger, Idan Segev

The rich dynamical nature of neurons poses major conceptual and technical challenges for unraveling their nonlinear membrane properties. Traditionally, various current waveforms have been injected at the soma to probe neuron dynamics, but the rationale for ...

EEG-MEG evidence for early differential repetition effects for fearful, happy and neutral faces

Nathalie George, Manuel Mercier

To deter-mine how emotional information modulates subsequent traces for repeated stimuli, we combined simultaneous electro-encephalography (EEG) and magneto-encephalography (MEG) measures during long-lag incidental repetition of fearful, happy, and neutral ...

Perceptual and semantic contributions to repetition priming of environmental sounds

Roberto Martuzzi, Stephanie Clarke

Repetition of environmental sounds, like their visual counterparts, can facilitate behavior and modulate neural responses, exemplifying plasticity in how auditory objects are represented or accessed. It remains controversial whether such repetition priming ...

Dynamic I-V curves are reliable predictors of naturalistic pyramidal-neuron voltage traces

Wulfram Gerstner, Carl Petersen, Laurent Badel, Sandrine Lefort, Romain Brette

Neuronal response properties are typically probed by intracellular measurements of current-voltage (I-V) relationships during application of current or voltage steps. Here we demonstrate the measurement of a novel I-V curve measured while the neuron exhibi ...

Virtual reality exposure therapy for social phobia

Bruno Herbelin

This thesis presents researches and experiments performed in collaboration with a psychiatrist in order to validate and improve the use of virtual reality in social phobia psychotherapy. Cognitive and behavioral therapies are strongly based on the exposure ...
