Cerebellar transcranial alternating current stimulation in the gamma range applied during the acquisition of a novel motor skill

Friedhelm Christoph Hummel, Takuya Morishita, Pablo Maceira Elvira, Manon Chloé Durand-Ruel, Maximilian Jonas Wessel, Chang-Hyun Park, Philipp Johannes Koch, Laurijn Rianne Draaisma, Anne Freija Willemijn De Boer

The development of novel strategies to augment motor training success is of great interest for healthy persons and neurological patients. A promising approach is the combination of training with transcranial electric stimulation. However, limited reproduci ...

Estimating the Readily-Releasable Vesicle Pool Size at Synaptic Connections in the Neocortex

Henry Markram, Eilif Benjamin Muller, Srikanth Ramaswamy, Rodrigo de Campos Perin, Natali Barros Zulaica, Giuseppe Chindemi

Previous studies based on the 'Quantal Model' for synaptic transmission suggest that neurotransmitter release is mediated by a single release site at individual synaptic contacts in the neocortex. However, recent studies seem to contradict this hypothesis ...

Neurobiological links between stress and anxiety

Maria del Carmen Sandi Perez

Stress and anxiety have intertwined behavioral and neural underpinnings. These commonalities are critical for understanding each state, as well as their mutual interactions. Grasping the mechanisms underlying this bidirectional relationship will have major ...

Latency to Reward Predicts Social Dominance in Rats: A Causal Role for the Dopaminergic Mesolimbic System

Maria del Carmen Sandi Perez, Simone Astori, Ioannis Zalachoras, Laura Lozano Montes, Sonia Abad Florensa

Reward signals encoded in the mesolimbic dopaminergic system guide approach/seeking behaviors to all varieties of life-supporting stimuli (rewards). Differences in dopamine (DA) levels have been found between dominant and submissive animals. However, it is ...

Norepinephrine stimulates glycogenolysis in astrocytes to fuel neurons with lactate

Pierre Magistretti, Henry Markram, Felix Schürmann, Daniel Keller, Jay Coggan, Corrado Cali

Although efficient compared to computers, the human brain utilizes energy at 10-fold the rate of other organs by mass. How the brain is supplied with sufficient on-demand energy to support its activity in the absence of neuronal storage capacity remains un ...

Stress Impacts the Regulation Neuropeptides in the Rat Hippocampus and Prefrontal Cortex

Gregor Rainer, Laura Lozano Montes, Nan Zhao

Adverse life experience increases the lifetime risk to several stress-related psychopathologies, such as anxiety or depressive–like symptom following stress in adulthood. However, the neurochemical modulations triggered by stress have not been fully charac ...

Brain-controlled modulation of spinal circuits improves recovery from spinal cord injury

Silvestro Micera, Grégoire Courtine, Marco Bonizzato, Polina Shkorbatova, Natalia Pavlova, Galyna Pidpruzhnykova

The delivery of brain-controlled neuromodulation therapies during motor rehabilitation may augment recovery from neurological disorders. To test this hypothesis, we conceived a brain-controlled neuromodulation therapy that combines the technical and practi ...

Inhaling xenon ameliorates l -dopa-induced dyskinesia in experimental parkinsonism

Grégoire Courtine, Eduardo Martin Moraud, Tomislav Milekovic, Shiqi Sun

Parkinson's disease motor symptoms are treated with levodopa, but long‐term treatment leads to disabling dyskinesia. Altered synaptic transmission and maladaptive plasticity of corticostriatal glutamatergic projections play a critical role in the pathophys ...

Current Overshoots and Undershoots in Electrical Stimulation: A Circuit-level Perspective of the Origin and Solutions

Alexandre Schmid, Reza Ranjandish

This paper investigates a common phenomenon in current mode stimulation which is known as current overshoots and undershoots. The origin of these abnormalities in the current pulses has remained an open issue and these overshoots and undershoots have been ...

Differentiating Siblings: The Case of Dopamine and Norepinephrine

Nako Nakatsuka

Monitoring dopamine and norepinephrine (or other structurally similar neurotransmitters) in the same brain region necessitates selective sensing. In this Viewpoint, we highlight electrochemical and optical strategies for advancing simultaneous real-time me ...
