General‐Purpose Ultrasound Neuromodulation System for Chronic, Closed‐Loop Preclinical Studies in Freely Behaving Rodents

Advanced Science, Volume 9, Issue 34, December 8, 2022., 2022
This work demonstrates a chronic, artifact‐free, and closed‐loop ultrasound stimulation system based on a capacitive micromachined ultrasound transducer for neuromodulation of the medial prefrontal cortex in mice. Stimulation during non‐rapid eye movement (NREM) sleep modulates REM sleep characteristics and short‐term spatial working memory ...

Transcranial focused ultrasound to human rIFG improves response inhibition through modulation of the P300 onset latency

eLife, 2023
Response inhibition in humans is important to avoid undesirable behavioral action consequences. Neuroimaging and lesion studies point to a locus of inhibitory control in the right inferior frontal gyrus (rIFG). Electrophysiology studies have implicated a

Neuromodulation Techniques in Chronic Cerebral Hypoperfusion: Mechanisms and Therapeutic Advances

CNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
Chronic cerebral hypoperfusion drives vascular cognitive impairment through neurovascular dysfunction, white matter injury, neuroinflammation, oxidative stress and synaptic network failure. Neuromodulation may offer a multi‐target strategy to restore plasticity, improve functional connectivity and support cognitive recovery. ABSTRACT Background Chronic
