Automated neuron tracking inside moving and deforming C. elegans using deep learning and targeted augmentation

Reading out neuronal activity from three-dimensional (3D) functional imaging requires segmenting and tracking individual neurons. This is challenging in behaving animals if the brain moves and deforms. The traditional approach is to train a convolutional n ...

Mechanisms of slab avalanche release and impact in the Dyatlov Pass incident in 1959

Johan Alexandre Philippe Gaume

The Dyatlov Pass incident is an intriguing unsolved mystery from the last century. In February 1959, a group of nine experienced Russian mountaineers perished during a difficult expedition in the northern Urals. A snow avalanche hypothesis was proposed, am ...

A modular strategy for next-generation upper-limb sensory-motor neuroprostheses

Silvestro Micera, Solaiman Shokur, Giuseppe Schiavone

Neuroprosthetics is a discipline that aims at restoring lost functions to people affected by a variety of neurological disorders or neuro-traumatic lesions. It combines the expertise of computer science and electrical, mechanical, and micro/nanotechnology ...

An overlapping pattern of cerebral cortical thinning is associated with both positive symptoms and aggression in schizophrenia via the ENIGMA consortium

Erick Jorge Canales Rodriguez, Wenhao Jiang

Background Positive symptoms are a useful predictor of aggression in schizophrenia. Although a similar pattern of abnormal brain structures related to both positive symptoms and aggression has been reported, this observation has not yet been confirmed in a ...

Brain-Controlled Neuroprosthetic Therapies And Mechanisms Of Recovery After Spinal Cord Injury

Galyna Pidpruzhnykova

Spinal cord injury (SCI) is the second leading cause of paralysis, which induces abrupt impairments with devastating consequences for the quality of life of patients. Despite significant progress in SCI treatment through neurorehabilitation training and sp ...

The Myosuit: Bi-articular Anti-gravity Exosuit That Reduces Hip Extensor Activity in Sitting Transfers

Muscle weakness—which can result from neurological injuries, genetic disorders, or typical aging—can affect a person's mobility and quality of life. For many people with muscle weakness, assistive devices provide the means to regain mobility and independen ...

[Neuronal control of posture and locomotion in decerebrated and spinalized animals]

Grégoire Courtine, Pavel Musienko

We have found that the brainstem-spinal cord circuitry of decerebrated cats actively maintain the equilibrium during standing, walking and imposed mechanical perturbations similar to that observed in intact animals. The corrective hindlimb motor responses ...

Somatosensory control of balance during locomotion in decerebrated cat

Grégoire Courtine, Pavel Musienko

Postmammillary decerebrated cats can generate stepping on a moving treadmill belt when the brain stem or spinal cord is stimulated tonically and the hindquarters are supported both vertically and laterally. While adequate propulsion seems to be generated b ...

What apraxia tells us about the brain hemispheres’ contributions to human imitation

Aude Billard, Biljana Petreska von Ritter-Zahony

Praxic functions are frequently altered following brain lesion, giving rise to apraxia - a complex pattern of impairments that has proven difficult to assess or interpret. Here we revisit a study on imitation of meaningless gestures in a patient with disco ...

Abnormal fear conditioning and amygdala processing in an animal model of autism

Maria del Carmen Sandi Perez, Henry Markram, Deborah La Mendola, Kamila Markram, Tania Rinaldi

A core feature of autism spectrum disorders is the impairment in social interactions. Among other brain regions, a deficit in amygdala processing has been suggested to underlie this impairment, but whether the amygdala is processing fear abnormally in auti ...
