Transcranial Pulsed Ultrasound Stimulates Intact Brain Circuits [PDF]

Neuron, 2010
Electromagnetic-based methods of stimulating brain activity require invasive procedures or have other limitations. Deep-brain stimulation requires surgically implanted electrodes. Transcranial magnetic stimulation does not require surgery, but suffers from low spatial resolution.

xTMS: A Pulse Generator for Exploring Transcranial Magnetic Stimulation Therapies

2023 IEEE Applied Power Electronics Conference and Exposition (APEC), 2023
A cascaded H-bridge based pulse generator for transcranial magnetic stimulation is introduced. The system demonstrates complete flexibility for producing different shape, duration, direction, and rate of repetition of stimulus pulses within its electrical limits, and can emulate all commercial and research systems available to-date in this application ...

Cortical Mechanisms of Single-Pulse Transcranial Magnetic Stimulation in Migraine [PDF]

Neurotherapeutics, 2020
Single-pulse transcranial magnetic stimulation (sTMS) of the occipital cortex is an effective migraine treatment. However, its mechanism of action and cortical effects of sTMS in migraine are yet to be elucidated. Using calcium imaging and GCaMP-expressing mice, sTMS did not depolarise neurons and had no effect on vascular tone. Pre-treatment with sTMS,

A specific phase of transcranial alternating current stimulation at the β frequency boosts repetitive paired-pulse TMS-induced plasticity

Scientific Reports, 2021
Transcranial alternating current stimulation (tACS) at 20 Hz (β) has been shown to modulate motor evoked potentials (MEPs) when paired with transcranial magnetic stimulation (TMS) in a phase-dependent manner.

A macroscopic link between interhemispheric tract myelination and cortico-cortical interactions during action reprogramming

Nature Communications, 2022
Myelination is a key regulator of brain function. Here the authors use MR-based myelin measures to examine if cortico-cortical interactions, as assessed by paired pulse transcranial magnetic stimulation, are affected by variations in myelin in the human ...

Alzheimer’s Pathogenesis and Treatment by Transcranial Pulse Stimulation

Open Access Macedonian Journal of Medical Sciences, 2023
The article discusses the use of transcranial pulse stimulation (TPS), a treatment method that uses ultrasound to penetrate the brain up to 8 cm. The article aims to review published studies on the effects of TPS on Alzheimer’s disease and to link the mechanism of the treatment with the pathophysiology of the disease.

Ultrasound stimulation of the motor cortex during tonic muscle contraction.

PLoS ONE, 2022
Transcranial ultrasound stimulation (tUS) shows potential as a noninvasive brain stimulation (NIBS) technique, offering increased spatial precision compared to other NIBS techniques. However, its reported effects on primary motor cortex (M1) are limited.

Transcranial static magnetic stimulation over the motor cortex can facilitate the contralateral cortical excitability in human

Scientific Reports, 2021
Transcranial static magnetic stimulation (tSMS) has been focused as a new non-invasive brain stimulation, which can suppress the human cortical excitability just below the magnet.

Dorsolateral Prefrontal Cortex: A Possible Target for Modulating Dyskinesias in Parkinson's Disease by Repetitive Transcranial Magnetic Stimulation

International Journal of Biomedical Imaging, 2008
We studied whether five sessions of 10 Hz repetitive transcranial magnetic stimulation (rTMS treatment) applied over the dorsolateral prefrontal cortex (DLPFC) or the primary motor cortex (MC) in advanced Parkinson's disease (PD) patients would have any ...
