Overexpression of human alpha-Synuclein leads to dysregulated microbiome/metabolites with ageing in a rat model of Parkinson disease

Hilal Lashuel, Yogesh Singh Chauhan, Florian Lang, Joan Romani Aumedes, Yogesh Singh

Background Braak's hypothesis states that sporadic Parkinson's disease (PD) follows a specific progression of pathology from the peripheral to the central nervous system, and this progression can be monitored by detecting the accumulation of alpha-Synuclei ...

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 ...

Three-dimensional multilayer concentric bipolar electrodes restrict spatial activation in optic nerve stimulation

Diego Ghezzi, Eleonora Borda, Marta Jole Ildelfonsa Airaghi Leccardi, Vivien Gaillet, Elodie Geneviève Zollinger, Ricardo Camilo Moreira

Objective. Intraneural nerve interfaces often operate in a monopolar configuration with a common and distant ground electrode. This configuration leads to a wide spreading of the electric field. Therefore, this approach is suboptimal for intraneural nerve ...

All-Polymer Printed Low-Cost Regenerative Nerve Cuff Electrodes

Silvestro Micera

Neural regeneration after lesions is still limited by several factors and new technologies are developed to address this issue. Here, we present and test in animal models a new regenerative nerve cuff electrode (RnCE). It is based on a novel low-cost fabri ...

Shedding light on excessive crying in babies

Dimitri Nestor Alice Van De Ville, François Lazeyras, Lorena Gonçalves de Alcântara e Freitas Krikler

Background Excessive and inconsolable crying behavior in otherwise healthy infants (a condition called infant colic (IC)) is very distressing to parents, may lead to maternal depression, and in extreme cases, may result in shaken baby syndrome. Despite the ...

Microfluidic device performing on flow study of serial cell–cell interactions of two cell populations

Philippe Renaud, Margaux Catherine Marie Duchamp, George Coukos, Thamani Dahoun, Alexandre Harari, Marion Arnaud

In this study we present a novel microfluidic hydrodynamic trapping device to probe the cell–cell interaction between all cell samples of two distinct populations. We have exploited an hydrodynamic trapping method using microfluidics to immobilize a batch ...

Computational modeling of the olfactory receptor Olfr73 suggests a molecular basis for low potency of olfactory receptor-activating compounds

Horst Vogel, Horst Pick, Shuguang Yuan, Thamani Dahoun, Marc Brugarolas Campillos

The mammalian olfactory system uses hundreds of specialized G-protein-coupled olfactory receptors (ORs) to discriminate a nearly unlimited number of odorants. Cognate agonists of most ORs have not yet been identified and potential non-olfactory processes m ...

A closed-loop hand prosthesis with simultaneous intraneural tactile and position feedback

Silvestro Micera, Stanisa Raspopovic, Francesco Maria Petrini, Edoardo D'Anna, Ivo Strauss, Giacomo Valle, Francesco Iberite

Current myoelectric prostheses allow transradial amputees to regain voluntary motor control of their artificial limb by exploiting residual muscle function in the forearm. However, the overreliance on visual cues resulting from a lack of sensory feedback i ...

Notch2 Signaling Maintains NSC Quiescence in the Murine Ventricular-Subventricular Zone

Freddy Radtke

Neurogenesis continues in the ventricular-subventricular zone (V-SVZ) of the adult forebrain from quiescent neural stem cells (NSCs). V-SVZ NSCs are a reservoir for new olfactory bulb (OB) neurons that migrate through the rostral migratory stream (RMS). To ...

The gram-negative sensing receptor PGRP-LC contributes to grooming induction in Drosophila

Bruno Lemaitre

Behavioral resistance protects insects from microbial infection. However, signals inducing insect hygiene behavior are still relatively unexplored. Our previous study demonstrated that olfactory signals from microbes enhance insect hygiene behavior, and gu ...

Subject-Independent Odor Pleasantness Classification Using Brain and Peripheral Signals

Touradj Ebrahimi, Jean-Marc Vesin, Eleni Kroupi

Enhanced sensation of reality from multimedia contents can be achieved by creating realistic multimedia environments, using visual, auditory, and olfactory information. Although the affective information from video and audio has been extensively studied, t ...

Exchanging ligand-binding specificity between a pair of mouse olfactory receptor paralogs reveals odorant recognition principles

Horst Vogel, Horst Pick, Shuguang Yuan, Luc Veya, Olivia Baud

A multi-gene family of ~1000 G protein-coupled olfactory receptors (ORs) constitutes the molecular basis of mammalian olfaction. Due to the lack of structural data its remarkable capacity to detect and discriminate thousands of odorants remains poorly unde ...

Fluctuation-driven neural dynamics reproduce Drosophila locomotor patterns

Dario Floreano, Pavan P Ramdya, Kyle Gustafson, Andrea Maesani

The neural mechanisms determining the timing of even simple actions, such as when to walk or rest, are largely mysterious. One intriguing, but untested, hypothesis posits a role for ongoing activity fluctuations in neurons of central action selection circu ...

Non-Linear EEG Features for Odor Pleasantness Recognition

Touradj Ebrahimi, Eleni Kroupi, Dionisije Sopic

Since olfactory sense is gaining ground in multimedia applications, it is important to understand the way odor pleasantness is perceived. Although several studies have explored the way odor pleasantness perception influences the power spectral density of t ...
