Progress in non-invasive neuromodulation based on consciousness-related neural circuits: a narrative review

Frontiers in Neurology
Disorders of Consciousness (DOC) are characterized by abnormal function or disrupted connectivity of consciousness-related neural circuits, mainly presenting as Vegetative State/Unresponsive Wakefulness Syndrome (VS/UWS) and Minimally Conscious State ...

Therapeutic effects of low-intensity transcranial focused ultrasound stimulation on ischemic stroke in rats: An in vivo evaluation using electrical impedance tomography

Neural Regeneration Research
Although previous studies have demonstrated that transcranial focused ultrasound stimulation protects the ischemic brain, clear criteria for the stimulation time window and intensity are lacking.

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

Advanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Computational modeling of a single-element transcranial focused ultrasound transducer for subthalamic nucleus stimulation [PDF]

Journal of Neural Engineering, 2019
Abstract Objective . While transcranial focused ultrasound is a very promising neuromodulation technique for its non-invasiveness and high spatial resolution, its application to the human deep brain regions such as the subthalamic nucleus (STN) is relatively new.

Reclassifying transcranial pulse stimulation as TNUS: Nonlinear mechanics necessitate departure from the ITRUSST framework

Brain Stimulation
Background: Transcranial ultrasound has emerged as a promising non-invasive neuromodulation modality for Alzheimer's disease (AD). However, its clinical translation is hindered by inconsistent biophysical classification between quasi-linear low-intensity

Polydopamine Nanoparticle‐Mediated Precise Near‐Infrared Optical Stimulation for Cognitive Enhancement

Advanced Science, EarlyView.
Polydopamine nanoparticles enable a precise, non‐genetic, and transcranial neuromodulation strategy via near‐infrared photothermal stimulation. By activating TRPV1 channels, this approach specifically enhances hippocampal gamma oscillations, thereby rescuing spatial memory deficits in models of perioperative neurocognitive disorder.

Effects of sonication parameters on transcranial focused ultrasound brain stimulation in an ovine model

PLOS ONE, 2019
Low-intensity focused ultrasound (FUS) has significant potential as a non-invasive brain stimulation modality and novel technique for functional brain mapping, particularly with its advantage of greater spatial selectivity and depth penetration compared to existing non-invasive brain stimulation techniques. As previous studies, primarily carried out in

Simultaneous acoustic stimulation of human primary and secondary somatosensory cortices using transcranial focused ultrasound [PDF]

BMC Neuroscience, 2016
Transcranial focused ultrasound (FUS) is gaining momentum as a novel non-invasive brain stimulation method, with promising potential for superior spatial resolution and depth penetration compared to transcranial magnetic stimulation or transcranial direct current stimulation. We examined the presence of tactile sensations elicited by FUS stimulation of
