Modulating fluency with Transcranial Magnetic Stimulation over right or left inferior frontal gyrus

2017

Objective In these last years, a growing body of evidence has already indicated that non-invasive brain stimulation techniques, such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), can modulate the language system in aphasic populations. The aim of this presentation is to investigate for the first time the effects of inhibitory rTMS over the left and right inferior frontal gyrus (IFG) on phonemic fluency tasks. Participants Sixty-six right-handed healthy participants participated in the study. Forty-four had administered offline low-frequency (1 Hz) rTMS for 10 minutes and verbal fluency outcome measures were recorded. Twenty-two participants w…

Transcranial Electrical and Magnetic Stimulation (tES and TMS) for Addiction Medicine: A Consensus Paper on the Present State of the Science and the …

2019

International audience; There is growing interest in non-invasive brain stimulation (NIBS) as a novel treatment option for substance-use disorders (SUDs). Recent momentum stems from a foundation of preclinical neuroscience demonstrating links between neural circuits and drug consuming behavior, as well as recent FDA-approval of NIBS treatments for mental health disorders that share overlapping pathology with SUDs. As with any emerging field, enthusiasm must be tempered by reason; lessons learned from the past should be prudently applied to future therapies. Here, an international ensemble of experts provides an overview of the state of transcranial-electrical (tES) and transcranial-magnetic…

Frequency-specific network activity predicts bradykinesia severity in Parkinson’s disease

2021

Highlights • Parallel subnetworks are affected in bradykinesia. • The primary motor and the premotor cortex are common nodes with task-specificity. • Beta activity decreases, gamma activity increases with improvement of bradykinesia. • Subthalamic stimulation reduces beta, increases gamma power in ipsilateral cortex. • Subnetworks act with frequency-specific oscillations.

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that allows the modulation of cortical excitability as well as neuroplastic reorganization using a weak constant current applied through the skull on the cerebral cortex. TDCS has been found to improve motor performance in general and motor learning in particular. However, these effects have been reported almost exclusively for unimanual motor tasks such as serial reaction time tasks, adaptation tasks, or visuo-motor tracking. Despite the importance of bimanual actions in most activities of daily living, only few studies have investigated the effects of tDCS on bimanual motor skills. The objectives …

The transcranial stimulation with direct currents (tdcs): An historical and conceptual minireview

2018

Transcranial Stimulation with Direct Currents (tDCS) is a method for non invasive brain stimulation created to induce functional changes in cerebral cortex. tDCS consists of application on the scalp of electrodes providing a low intensity direct current influencing neuronal functions. tDCS is not the only neurostimulation method for neuroscience clinical practice and research and can be used for treat many different clinical conditions such as migraine prevention, autism spectrum disorders (ASD), cerebral palsy rehabilitation, post-traumatic brain injury neuropsychological disorders.

Neuromodulation of chronic headaches: position statement from the European Headache Federation

2013

The medical treatment of patients with chronic primary headache syndromes (chronic migraine, chronic tension-type headache, chronic cluster headache, hemicrania continua) is challenging as serious side effects frequently complicate the course of medical treatment and some patients may be even medically intractable. When a definitive lack of responsiveness to conservative treatments is ascertained and medication overuse headache is excluded, neuromodulation options can be considered in selected cases.Here, the various invasive and non-invasive approaches, such as hypothalamic deep brain stimulation, occipital nerve stimulation, stimulation of sphenopalatine ganglion, cervical spinal cord sti…

Brain stimulation in migraine

2013

Migraine is a very prevalent disease with great individual disability and socioeconomic burden. Despite intensive research effort in recent years, the etiopathogenesis of the disease remains to be elucidated. Recently, much importance has been given to mechanisms underlying the cortical excitability that has been suggested to be dysfunctional in migraine. In recent years, noninvasive brain stimulation techniques based on magnetic fields (transcranial magnetic stimulation, TMS) and on direct electrical currents (transcranial direct current stimulation, tDCS) have been shown to be safe and effective tools to explore the issue of cortical excitability, activation, and plasticity in migraine.
