Role and mechanism of transient receptor potential (TRP) channels in gustatory and chemesthetic sensations associated with dietary molecules

"Chemosensory perception", the perception of food chemicals, relies on the complex cooperation of gustatory, olfactory and somatosensory detection systems. In the oral cavity, the taste buds and the lingual branch of the trigeminal nerve are the organs tha ...

Neurocomputational modeling of imitation deficits

Aude Billard, Biljana Petreska von Ritter-Zahony

We are interested in the question of human imitation and we address this through convergent evidence from neuroscience. The rationale of our work is that the nature of imitation deficits following brain lesion can unveil some of the neural and computationa ...

Mapping the Structural Core of Human Cerebral Cortex

Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet, Olaf Sporns

Structurally segregated and functionally specialized regions of the human cerebral cortex are interconnected by a dense network of cortico-cortical axonal pathways. Using diffusion spectrum imaging we noninvasively map these pathways within and across cort ...

The excitatory neuronal microcircuit of the C2 column in the mouse primary somatosensory cortex

Sandrine Lefort

Rodents are nocturnal animals gathering information about their surroundings by using highly sensitive detectors laid out on their snout. Like humans use their fingertips to apprehend textures, rodents use their whiskers to build a spatial representation o ...

Two-arm haptic force-feedbacked aid for the shoulder and elbow telerehabilitation

Daniel Thalmann, Patrick Salamin, Frédéric Vexo

In this paper, we present a telerehabilitation system aiming to help the physiotherapists for the shoulder and elbow treatment. It is based on a two-arm haptic force feedback to avoid excessive efforts and discomfort with the spinal column. This system, re ...

The functional organization of the barrel cortex

Carl Petersen

The tactile somatosensory pathway from whisker to cortex in rodents provides a well-defined system for exploring the link between molecular mechanisms, synaptic circuits, and behavior. The primary somatosensory cortex has an exquisite somatotopic map where ...

Stance- and locomotion-dependent processing of vibration-induced proprioceptive inflow from multiple muscles in humans

Grégoire Courtine

We performed a whole-body mapping study of the effect of unilateral muscle vibration, eliciting spindle Ia firing, on the control of standing and walking in humans. During quiet stance, vibration applied to various muscles of the trunk-neck system and of t ...

Chronic restraint stress down-regulates amygdaloid expression of polysialylated neural cell adhesion molecule

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

The amygdala is a brain area which plays a decisive role in fear and anxiety. Since exposure to chronic stress can induce profound effects in emotion and cognition, plasticity in specific amygdaloid nuclei in response to prior stress has been hypothesized ...

Diffusion Spectrum Imaging Tractography in Complex Cerebral White Matter: An Investigation of the Centrum Semiovale

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Van Jay Wedeen

DSI is a novel high angular resolution diffusion MR imaging technique with high b-values that is able to map complex white matter architecture in the brain. We evaluate the capacity of a simple tractography method to define the essential fiber crossing ana ...

Regulation of brain proteolytic activity is necessary for the in vivo function of NMDA receptors

Carl Petersen, Sandrine Lefort

Serine proteases are considered to be involved in plasticity-related events in the nervous system, but their in vivo targets and the importance of their control by endogenous inhibitors are still not clarified. Here, we demonstrate the crucial role of a po ...
