The antidepressant-like effect of tDCS in mice: A behavioral and neurobiological characterization
2017
Abtract Background Transcranial direct current stimulation (tDCS) is a non-invasive method increasingly popular for the treatment of several brain disorders, such as major depression. Despite great enthusiasm and promising results, some studies report discrepant findings and no consensus exists for the clinical use of tDCS. Objective The present study aims to (i) determine the most effective stimulation parameters to optimize antidepressant-like effect of tDCS in the forced-swim test in mice and (ii) identify brain regions recruited by tDCS and possibly involved in its behavioral effect using Fos immunohistochemistry. Results We reported that tDCS induced long-lasting antidepressant-like ef…
The Etiology of Muscle Fatigue Differs between Two Electrical Stimulation Protocols
2016
International audience; Purpose: This study aimed at investigating the mechanisms involved in the force reduction induced by two electrical stimulation (ES) protocols that were designed to activate motor units differently. Methods: The triceps surae of 11 healthy subjects (8 men; age, similar to 28 yr) was activated using ES applied over the tibial nerve. Two ES protocols (conventional [CONV]: 20 Hz, 0.05 ms vs wide-pulse high-frequency [WPHF]: 80 Hz, 1 ms) were performed and involved 40 trains (6 s on-6 s off) delivered at an intensity (I-ES) evoking 20% of maximal voluntary contraction. To analyze the mechanical properties of the motor units activated at I-ES, force-frequency relation was…
