Functional mapping of the cortical areas dedicated to the perception of touch revealed with unprecedented precision in mice

The primary somatosensory cortex (S1) of rodents has become a major model to study the cortical processing of tactile sensory information. A large portion of this cortical area is dedicated to the processing of information originating from the whiskers (vibrissae) on the animal’s face. However, upon vibrissal stimulation, tactile information first reaches S1 but also, almost simultaneously, the secondary somatosensory cortex (S2). To better understand the role of S2 in the perception of touch, it is essential to properly characterize the neuronal responses evoked by tactile stimuli in this cortical area. To do this, researchers have taken advantage of the excellent spatial and temporal resolution of voltage sensitive dye imaging.

The results are reported in Scientific Reports on January 21st, 2020.

Coding Stratégies in Vertebrate Acoustic Communication

This book focuses on how animal acoustic signals code information and how this coding can be shaped by various environmental and social constraints.
- Highlights all aspects of the communication chain, as defined by the Mathematical Theory of Communication.
- Provides new insights into the acoustic coding strategies of animals exchanging information.
- Broadens readers’ understanding of the mechanisms and evolution of complex animal communication systems.

Evolution of acoustic communication in blind cavefish

Acoustic communication allows the exchange of information within specific contexts and during specific behaviors. The blind, cave-adapted and the sighted, river-dwelling morphs of the species Astyanax mexicanus have evolved in markedly different environments. During their evolution in darkness, cavefish underwent a series of morphological, physiological and behavioral changes, allowing the study of adaptation to drastic environmental change.
