Researchers identify brain circuits responsible for triggering OCD symptoms

Most of the time, the origin of obsessive-compulsive disorder (OCD) is unknown, but in some rare cases, it starts after a brain injury, such as a stroke or a tumor.

Electroacupuncture at Lianquan point restores post-stroke swallowing function

Swallowing is a complex act requiring precise coordination of the mouth, throat, and voice box. After a stroke, damage to the brain's motor cortex can disrupt swallowing-related neural commands, leaving patients unable to clear food or liquid from their throat safely.

Scientists discover rotating brain waves that coordinate sensory information

Spiraling waves of neural activity appear and travel in the brain. Scientists hope to learn if these rotating waves on-the-move play a global role in sensing and interpreting internal and external stimuli, in laying down memory, and in managing motor performance.

Gut microbes may help explain why obesity and type 2 diabetes become harder to reverse

This review describes how gut microbial messengers, including SCFAs, microbiota-modified bile acids, neuroactive metabolites, and extracellular vesicles, may shape obesity and type 2 diabetes through the microbiota-gut-brain axis.

Deep brain stimulation rewires brain circuits linked to depression

Researchers from the Icahn School of Medicine at Mount Sinai have uncovered the first direct evidence that deep brain stimulation (DBS) can remodel white matter pathways in the brain and alter communication across large-scale neural networks, revealing a previously unrecognized mechanism that may explain how the therapy helps patients recover from severe depression.

Study reveals how magnetic stimulation repairs depression-related brain circuits

Transcranial magnetic stimulation (TMS) is a non-invasive, FDA-approved therapy that uses brief magnetic pulses to treat depression, particularly in patients who do not respond to medication.

Mapping brain circuits helps identify the causes of psychiatric symptoms

If a small stroke in one corner of the brain can tip a previously healthy person into mania or set off obsessions and compulsions where none existed before, then the circuit connected to that lesion is telling us something rare in psychiatry.

Study reveals brain mechanisms behind post-stroke urinary incontinence

A new USC-led study using functional magnetic resonance imaging (fMRI) reveals the neural mechanisms that contribute to urinary incontinence, a common condition affecting stroke survivors that has a significant impact on their quality of life.
