Evolution of Acid-Sensing Olfactory Circuits in Drosophilids

Animals adapt their behaviors to specific ecological niches, but the genetic and cellular basis of nervous system evolution is poorly understood. We have compared the olfactory circuits of the specialist Drosophila sechellia-which feeds exclusively on Mori ...

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 ...

Boosting olfactory cocktail-party performance by semi-supervised learning in mice

Alexander Mathis, Matthias Bethge

Mice are excellent at detecting single odor components in complex mixtures. Yet, when they are trained on single odors alone, they fail to reliably detect target odors in mixtures of multiple odorants. This inability was predicted by a linear readout that ...

Reading Out Olfactory Receptors: Feedforward Circuits Detect Odors in Mixtures without Demixing

Alexander Mathis, Matthias Bethge

The olfactory system, like other sensory systems, can detect specific stimuli of interest amidst complex, varying backgrounds. To gain insight into the neural mechanisms underlying this ability, we imaged responses of mouse olfactory bulb glomeruli to mixt ...

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 ...

A Graph-Based Formation Algorithm for Odor Plume Tracing

Alcherio Martinoli, Jorge Miguel Dias Almeida Rodrigues Soares

Odor plume tracing is a challenging robotics application, made difficult by the combination of the patchy characteristics of odor distribution and the slow response of the available sensors. This work proposes a graph-based formation control algorithm to c ...

Bioinspired Selective Surface Deposition of Fragrance Delivery Systems

Kemal Arda Günay

The perception of pleasantness in many of the consumer goods is provided by volatile chemical compounds called fragrances. While the volatility of fragrances is essential to provide a pleasant olfactory response, it presents at the same time a technologi ...

Neuroligin-2 expression in the prefrontal cortex is involved in attention deficits induced by peripubertal stress

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Stamatina Tzanoulinou, Orbicia Riccio Wicht

Emerging evidence indicates that attention deficits, which are frequently observed as core symptoms of neuropsychiatric disorders, may be elicited by early life stress. However, the mechanisms mediating these stress effects remain unknown. The prefrontal c ...

Multimodal stimulus coding by a gustatory sensory neuron in Drosophila larvae

Philippe Renaud

Accurate perception of taste information is crucial for animal survival. In adult Drosophila, gustatory receptor neurons (GRNs) perceive chemical stimuli of one specific gustatory modality associated with a stereotyped behavioural response, such as aversio ...
