Lamellar Schwann Cells in the Pacinian Corpuscle Potentiate Vibration Perception

Graham Knott, Mary-Claude Croisier-Coeytaux, Jérôme Blanc, Stéphanie Clerc

Pacinian corpuscles are among the most sensitive mechanoreceptors found in vertebrates, and they are tuned to vibrations in the highest perceptible frequency range (100 to 2000 Hz). One of their anatomical hallmarks is the onion-like cell layers surroundin ...

Neural anticipation of virtual infection triggers an immune response

Tommaso Enrico Bertoni

Once contact with a pathogen has occurred, it might be too late for the immune system to react. Here, we asked whether anticipatory neural responses might sense potential infections and signal to the immune system, priming it for a response. We show that p ...

Membrane mechanics dictate axonal pearls-on-a-string morphology and function

Graham Knott

Axons are ultrathin membrane cables that are specialized for the conduction of action potentials. Although their diameter is variable along their length, how their morphology is determined is unclear. Here, we demonstrate that unmyelinated axons of the mou ...

Closed-Loop Control and Disturbance Mitigation of an Underwater Multi-Segment Continuum Manipulator

Kyle Liam Walker

The use of soft and compliant manipulators in marine environments represents a promising paradigm shift for subsea inspection, with devices better suited to tasks owing to their ability to safely conform to items during contact. However, limitations driven ...

Learning-based Hierarchical Control: Emulating the Central Nervous System for Bio-Inspired Legged Robot Locomotion

Auke Ijspeert, Guillaume Denis Antoine Bellegarda, Milad Shafiee Ashtiani

Animals possess a remarkable ability to navigate challenging terrains, achieved through the interplay of various pathways between the brain, central pattern generators (CPGs) in the spinal cord, and musculoskeletal system. Traditional bioinspired control f ...

Cerebro-spinal somatotopic organization uncovered through functional connectivity mapping

Dimitri Nestor Alice Van De Ville, Nawal Noëlle Kinany

Somatotopy, the topographical arrangement of sensorimotor pathways corresponding to distinct body parts, is a fundamental feature of the human central nervous system (CNS). Traditionally, investigations into brain and spinal cord somatotopy have been condu ...

Synaptic architecture of leg and wing premotor control networks in Drosophila

Jasper Taylor Phelps

Animal movement is controlled by motor neurons (MNs), which project out of the central nervous system to activate muscles(1). MN activity is coordinated by complex premotor networks that facilitate the contribution of individual muscles to many different b ...

Diffusion of brain metabolites highlights altered brain microstructure in type C hepatic encephalopathy: a 9.4 T preliminary study

Cristina Ramona Cudalbu Moldovan, Dunja Simicic, Katarzyna Pierzchala, Jessie Julie Mosso, Guillaume Miro André Briand

Introduction Type C hepatic encephalopathy (HE) is a decompensating event of chronic liver disease leading to severe motor and cognitive impairment. The progression of type C HE is associated with changes in brain metabolite concentrations measured by 1H m ...

Noninvasive modulation of the hippocampal-entorhinal complex during spatial navigation in humans

Olaf Blanke, Friedhelm Christoph Hummel, Maximilian Jonas Wessel, Elena Beanato, Traian Popa, Pierre Theopistos Vassiliadis, Baptiste Gauthier, Emanuela De Falco, Fabienne Windel, Pauline Menoud, Hyukjun Moon, Esra Neufeld

Because of the depth of the hippocampal-entorhinal complex (HC-EC) in the brain, understanding of its role in spatial navigation via neuromodulation was limited in humans. Here, we aimed to better elucidate this relationship in healthy volunteers, using tr ...

MEP and TEP features variability: is it just the brain-state?

Friedhelm Christoph Hummel, Estelle Emeline Raffin, Sylvain Jean-François Harquel, Andéol Geoffroy Cadic-Melchior, Michele Bevilacqua, Claudia Bigoni

Objective. The literature investigating the effects of alpha oscillations on corticospinal excitability is divergent. We believe inconsistency in the findings may arise, among others, from the electroencephalography (EEG) processing for brain-state determi ...

Single-cell and spatial atlases of spinal cord injury in the Tabulae Paralytica

Grégoire Courtine, Bernard Schneider, Jocelyne Bloch, Quentin Barraud, Claudia Kathe, Matthieu Pierre Gautier, Nicholas David James, Thomas Haynes Hutson, Michael Alexander Skinnider, Achilleas Laskaratos, Michael V. Sofroniew, Nicola Aldo Regazzi

Here, we introduce the Tabulae Paralytica—a compilation of four atlases of spinal cord injury (SCI) comprising a single-nucleus transcriptome atlas of half a million cells, a multiome atlas pairing transcriptomic and epigenomic measurements within the same ...

Using a wearable micro-camera for dynamic glare evaluation: Corrections and verification assessment

Jan Wienold

Micro-cameras such as the 'vision-in-package' (VIP) can be used as a wearable for user-centric glare estimations. Yet, there is a lack of methodologies to use such head-mounted device and their outputs to obtain reliable glare evaluations. This paper focus ...
