Targeting Gamma-Related Pathophysiology

Link – Targeting Gamma-Related Pathophysiology in Autism Spectrum Disorder Using Transcranial Electrical Stimulation: Opportunities and Challenges. Abstract A range of scalp electroencephalogram (EEG) abnormalities correlates with the core symptoms of autism spectrum disorder (ASD). Among these are alterations of brain oscillations in the gamma-frequency EEG band in adults and children with ASD, whose origin has […]

Modeling radio-frequency energy-induced heating from tES

Link – Modeling radio-frequency energy-induced heating due to the presence of transcranial electric stimulation setup at 3T. Abstract PURPOSE: The purpose of the present study was to develop a numerical workflow for simulating temperature increase in a high-resolution human head and torso model positioned in a whole-body magnetic resonance imaging (MRI) radio-frequency (RF) coil in […]

Benchmarking transcranial electrical stimulation finite element models

Link – Benchmarking transcranial electrical stimulation finite element models: a comparison study. Abstract OBJECTIVE: To compare field measure differences in simulations of transcranial electrical stimulation (tES) generated by variations in finite element (FE) models due to boundary condition specification, use of tissue compartment smoothing filters, and use of free or structured tetrahedral meshes based on […]

Locations for brain stimulation in depressive disorders

Link – Locations for noninvasive brain stimulation in treating depressive disorders: A combination of meta-analysis and resting-state functional connectivity analysis. Abstract OBJECTIVE: Many noninvasive brain stimulation techniques have been applied to treat depressive disorders. However, the target brain region in most noninvasive brain stimulation studies is the dorsolateral prefrontal cortex. Exploring new stimulation locations may […]

Guidelines for TMS/tES Research through the COVID-19

Link – Guidelines for TMS/tES Clinical Services and Research through the COVID-19 Pandemic. Abstract BACKGROUND: The COVID-19 pandemic has broadly disrupted biomedical treatment and research including non-invasive brain stimulation (NIBS). Moreover, the rapid onset of societal disruption and evolving regulatory restrictions may not have allowed for systematic planning of how clinical and research work may […]

Analyzing the advantages of subcutaneous over tES

Link – Analyzing the advantages of subcutaneous over transcutaneous electrical stimulation for activating brainwaves. Abstract Transcranial electrical stimulation (TES) is a widely accepted neuromodulation modality for treating brain disorders. However, its clinical efficacy is fundamentally limited due to the current shunting effect of the scalp and safety issues. A newer electrical stimulation technique called subcutaneous […]

tES on episodic memory in ageing.

Link – Effects of transcranial electrical stimulation on episodic memory in physiological and pathological ageing. Abstract Memory for personally past events (episodic memory) is critical for activities of daily living. Decline in this type of declarative long-term memory is a common characteristic of healthy ageing, a process accelerated in patients with mild cognitive impairment (MCI) […]

Vision plasticity and restoration using non-invasive brain stimulation

Link – Vision modulation, plasticity and restoration using non-invasive brain stimulation – An IFCN-sponsored review. Abstract The visual system has one of the most complex structures of all sensory systems and is perhaps the most important sense for everyday life. Its functional organization was extensively studied for decades in animal and humans, for example by […]

tES optimizes the balance of visual attention across space.

Link – Transcranial electric stimulation optimizes the balance of visual attention across space. Clin Neurophysiol. 2020 Jan 31;131(4):912-920 Authors: Andres M, Masson N, Larigaldie N, Bonato M, Vandermeeren Y, Dormal V Abstract OBJECTIVE: Transcranial direct current stimulation (tDCS) provides a way to modulate spatial attention by enhancing the ratio of neural activity between the left […]

High spatial resolution neurostimulation.

Link – A multiple modulation synthesis method with high spatial resolution for noninvasive neurostimulation. PLoS One. 2019;14(6):e0218293 Authors: Xiao Q, Zhong Z, Lai X, Qin H Abstract Noninvasive neurostimulation plays a pivotal role in the direct control of neural circuits and the modulation of neuronal function. However, it is difficult to balance both spatial resolution […]
