Transient brain activity dynamics discriminate levels of consciousness during anesthesia

Dimitri Nestor Alice Van De Ville, Elvira Pirondini, Ayberk Ozkirli

The awake mammalian brain is functionally organized in terms of large-scale distributed networks that are constantly interacting. Loss of consciousness might disrupt this temporal organization leaving patients unresponsive. We hypothesize that characterizi ...

Loss of Motor Cortical Inputs to the Red Nucleus after CNS Disorders in Nonhuman Primates

Simon Borgognon

The premotor (PM) and primary motor (M1) cortical areas broadcast voluntary motor commands through multiple neuronal pathways, including the corticorubral projection that reaches the red nucleus (RN). However, the respective contribution of M1 and PM to co ...

Digital reconstruction of the mammalian spinal cord: from anatomical reference volume to cell type atlas of the mouse spinal cord

Ihor Kuras

The spinal cord is an elongated nervous structure that together with the brain forms the central nervous system. It relays sensory and motor information between the brain and the body, thus controlling most somatic and autonomic body functions. In recent y ...

Creating a neuroprosthesis for active tactile exploration of textures

Solaiman Shokur, Miguel Nicolelis

Intracortical microstimulation (ICMS) of the primary somatosensory cortex (S1) can produce percepts that mimic somatic sensation and, thus, has potential as an approach to sensorize prosthetic limbs. However, it is not known whether ICMS could recreate act ...

EXiO-A Brain-Controlled Lower Limb Exoskeleton for Rhesus Macaques

Hannes Bleuler, Mohamed Bouri, Jeremy Olivier, Miguel Nicolelis, Tristan Hubert Vouga

Recent advances in the field of brain-machine interfaces (BMIs) have demonstrated enormous potential to shape the future of rehabilitation and prosthetic devices. Here, a lower-limb exoskeleton controlled by the intracortical activity of an awake behaving ...

Biodegradable scaffolds promote tissue remodeling and functional improvement in non-human primates with acute spinal cord injury

Grégoire Courtine, Isabel Laura Vollenweider

Tissue loss significantly reduces the potential for functional recovery after spinal cord injury. We previously showed that implantation of porous scaffolds composed of a biodegradable and biocompatible block copolymer of Poly-lactic-co-glycolic acid and P ...

Probable nature of higher-dimensional symmetries underlying mammalian grid-cell activity patterns

Alexander Mathis

Lattices abound in nature—from the crystal structure of minerals to the honey-comb organization of ommatidia in the compound eye of insects. These arrangements provide solutions for optimal packings, efficient resource distribution, and cryptographic proto ...

Tonotopic organization in monkey and human auditory cortex using phase-encoded functional MRI

Melissa Saenz, Wietske Van der Zwaag, Naghmeh Ghazaleh, Gaëlle Chapuis

Tonotopic organization is the main topographic feature of the primary auditory cortex. Importantly, tonotopy allows to define borders of cortical areas as reversals of the frequency gradient (i.e the spatial derivative of the preferred frequency map). Very ...

Organic semiconductors for artificial vision

Diego Ghezzi

Organic semiconductors have emerged in the past two decades as promising materials for many technological applications. Thanks to their unique optoelectronic properties, they represent an ideal system to mimic natural photoreceptor functioning. This simila ...

Methods for Functional Assessment After C7 Spinal Cord Hemisection in the Rhesus Monkey

Grégoire Courtine

Background. Reliable outcome measures are essential for preclinical modeling of spinal cord injury (SCI) in primates. Measures need to be sensitive to both increases and decreases in function in order to demonstrate potential positive or negative effects o ...
