Time and the brain: neurorelativity. The chronoarchitecture of the brain from the neuronal rather than the observer's perspective

Naturally, neuroscientists look at the brain from the outside when measuring how the flow of information unfolds over space and time. A neuron, on the other hand, can only 'see' through its connections, and they are spatiotemporally limited. Hence, the neu ...

New insights into the classification and nomenclature of cortical GABAergic interneurons

Henry Markram, Sean Lewis Hill, Yun Wang, Ruth Benavides Piccione, Jean Rossier, Zoltan Kisvarday

A systematic classification and accepted nomenclature of neuron types is much needed but is currently lacking. This article describes a possible taxononnical solution for classifying GABAergic interneurons of the cerebral cortex based on a novel, web-based ...

Bimanual brain-machine interface

Solaiman Shokur, Miguel Nicolelis, Mikhail Lebedev, Zheng Li

Brain-machine interfaces (BMIs) - devices that connect brain areas to external actuators - strive to restore limb mobility and sensation to patients suffering from paralysis or limb loss. Here we report a novel BMI that controls two virtual arms simultaneo ...

Assessing the integrity of corticospinal pathways from primary and secondary cortical motor areas after stroke

Friedhelm Christoph Hummel, Chang-Hyun Park

Aside from the primary motor cortex, the corticospinal tract (CST) also receives fibers from dorsal and ventral premotor cortices and supplementary motor area, all of which might potentially contribute to motor function after stroke. We sought to quantify ...

Assessing functional connectivity of neural ensembles using directed information

Michael Christoph Gastpar

Neurons in the brain form highly complex networks through synaptic connections. Traditionally, functional connectivity between neurons has been explored using methods such as correlations, which do not contain any notion of directionality. Recently, an inf ...

A Hybrid Bio-Organic Interface For Neuronal Photo-Activation

Diego Ghezzi

A key issue toward the realization of retinal prosthetic devices is a reliable transduction of the information carried by light into specific patterns of electrical activity at the level of the networks involved in visual information processing. In this pe ...

Continuous decoding of grasping tasks for a prospective implantable cortical neuroprosthesi

Silvestro Micera

Background: In the recent past several invasive cortical neuroprostheses have been developed. Signals recorded from the motor cortex (area MI) have been decoded and used to control computer cursors and robotic devices. Nevertheless, few attempts have been ...

Proprioceptive Coupling within Motor Neurons Drives C. elegans Forward Locomotion

Matthieu Wyart, Xinyu Liu

Locomotion requires coordinated motor activity throughout an animal@s body. In both vertebrates and invertebrates, chains of coupled central pattern generators (CPGs) are commonly evoked to explain local rhythmic behaviors. In C. elegans, we report that pr ...

Mesenchymal stem cells restore cortical rewiring after neonatal ischemia in mice

Yohan Van de Looij

Objective: A study was undertaken to investigate the effect of neonatal hypoxic-ischemic (HI) brain damage and mesenchymal stem cell (MSC) treatment on the structure and contralesional connectivity of motor function-related cerebral areas. Methods: Brain r ...

Acquired control of ventral premotor cortex activity by feedback training: an exploratory real-time FMRI and TMS study

Friedhelm Christoph Hummel

Despite the availability of various options for movement restoration in stroke patients, there is no effective treatment for patients who show little or no functional recovery of upper limb motor function. ...
