The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Blood biomarker test improves detection of hidden brain injuries

Clinician-scientists hope to expand the use of blood-based biomarker tests for traumatic brain injury (TBI) to improve identification and escalation of care for patients whose diagnosis otherwise might be missed.

Research shows how the brain merges faces and voices to read emotions

Communicating effectively with others involves recognizing emotions from faces and voices. How does the brain process and integrate emotional information from visuals and sounds that others display? New in JNeurosci, Olivier Collignon, from the Catholic University of Louvain, Stefania Mattioni, currently at Ghent University, and colleagues mapped responses in people's brains to faces and voices expressing different emotions.

New study explores psychedelic therapy for co-occurring cocaine addiction and depression

A team of UTHealth Houston researchers has been awarded a five-year, $3.4 million grant to study whether psilocybin-assisted therapy is a viable treatment option for individuals with co-occurring cocaine use disorder and major depressive disorder.

Stem cell therapies may need new protein quality control standards

Current Good Manufacturing Practice (GMP) standards for cell therapies assess identity, viability, sterility, and genetic stability. For extracellular vesicle (EV) products, Minimal Information for Studies of Extracellular Vesicles (MISEV2023) guidance adds particle size, concentration, markers, morphology, contaminants, endotoxin, and assays.

Accelerated TMS cuts depression treatment time from six weeks to three

Transcranial magnetic stimulation (TMS) has proved to be a very effective non-invasive treatment for people with severe depression who have not had success with medication. But traditional TMS has one significant drawback: time.

Newer anticoagulants linked to fewer strokes and deaths after brain bleeds

For people with atrial fibrillation (AFib), an irregular heartbeat, and intracranial hemorrhage, a type of stroke also known as a brain bleed, anticoagulant use was associated with a lower risk of an ischemic stroke and death, according to a new study published October 21, 2026, in Neurology®, the official medical journal of the American Academy of Neurology.
