Transcranial alternating current stimulation for schizophrenia: a systematic review of randomized controlled studies

Frontiers in Psychiatry
Background In randomized clinical trials (RCTs) investigating the application of transcranial alternating current stimulation (tACS) in schizophrenia, inconsistent results have been reported.

Phase Dependency of the Human Primary Motor Cortex and Cholinergic Inhibition Cancelation during Beta tACS [PDF]

, 2016
The human motor cortex has a tendency to resonant activity at about 20 Hz so stimulation should more readily entrain neuronal populations at this frequency.

Transcranial alternating current stimulation entrains alpha oscillations by preferential phase synchronization of fast-spiking cortical neurons to stimulation waveform

Nature Communications, 2021
Computational modeling and human studies suggest that transcranial alternating current stimulation (tACS) modulates alpha oscillations by entrainment. Yet, a direct examination of how tACS interacts with neuronal spiking activity that gives rise to the ...

Time‐Dependent Therapeutic Effect of S‐Ketamine on PTSD Mediated by VTA‐OFC Dopaminergic Neurocircuit

Advanced Science, EarlyView.
This study reveals that early rather than late administration of S‐ketamine can ameliorate PTSD symptoms. This phenomenon is attributed to reversing the progressive inhibition of VTADA neurons and the function of VTADA‐OFC circuit following stress. Targeted stimulation of the OFC by TI‐NIBS to enhance DA release effectively extends the therapeutic time

Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

Advanced Science, EarlyView.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.
