Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, EarlyView.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

Transcranial direct current stimulation (tDCS) and language [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2012
Transcranial direct current stimulation (tDCS), a non-invasive neuromodulation technique inducing prolonged brain excitability changes and promoting cerebral plasticity, is a promising option for neurorehabilitation. Here, we review progress in research on tDCS and language functions and on the potential role of tDCS in the treatment of post-stroke ...

Advancing Dry Electroencephalography With Scalable, Soft, and Transcranial Magnetic Stimulation‐Compatible Ti3C2Tx MXene Electrodes for Research and Clinical‐Grade Applications

Advanced Science, EarlyView.
Dry soft Ti3C2Tx MXene electroencephalography (EEG) electrodes provide low impedance (2.1 ± 1.8 kΩ at 10 Hz), long‐term stability, and enable safe simultaneous EEG and transcranial magnetic stimulation (TMS). Across scalp sites, hair types, and recording paradigms, including steady state visual evoked potentials (SSVEP), clinical EEG, and mobile EEG ...

Efficacy of anodal transcranial direct current stimulation for upper extremity function after ischemic stroke: A systematic review of parallel randomized clinical trials

Journal of Stroke and Cerebrovascular Diseases
Background: Although existing studies had shown therapeutic effects of transcranial direct current stimulation (tDCS) on upper limb dysfunction after stroke, previous systematic reviews had mostly provided general analyses on the polarity of tDCS and the

Transcranial Direct Current Stimulation in Stroke Recovery [PDF]

Archives of Neurology, 2008
Transcranial direct current stimulation (TDCS) is an emerging technique of noninvasive brain stimulation that has been found useful in examining cortical function in healthy subjects and in facilitating treatments of various neurologic disorders. A better understanding of adaptive and maladaptive poststroke neuroplasticity and its modulation through ...

Ultrasound Modulation of Visual Circuits in Mice Independent of Auditory Confound

Advanced Science, EarlyView.
In this study, Qiu et al. found that low‐intensity ultrasound can directly activate sparse ultrasound‐sensitive neurons (UNs) in the primary visual cortex (V1) of deafened mice. The proportion of these sparse UNs is pressure‐dependent. Furthermore, ultrasound modulates visual circuitry with distinct excitatory and inhibitory effects.

Repetitive transcranial magnetic stimulation or transcranial direct current stimulation?

Brain Stimulation, 2009
In recent years two techniques have become available to stimulate the human brain noninvasively through the scalp: repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS). Prolonged application of either method (eg, several hundred TMS pulses [rTMS] or several minutes of tDCS) leads to changes in ...

Ultrasound Activated Piezoelectric Dural Patches to Drive Endogenous Neural Stem Cell–Mediated Repair Traumatic Brain Injury

Advanced Science, EarlyView.
This study presents a wireless, non‐invasive strategy for neural repair by developing a biodegradable piezoelectric dural patch that, under transcranial ultrasound, generates localized electrical fields to drive endogenous neural stem cells toward neuronal differentiation and functional integration.

Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

Annals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.
