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.

Study: Biological underpinnings of autism and ADHD may transcend traditional diagnostic boundaries

A new study published in Molecular Psychiatry reveals that the biological underpinnings of autism and ADHD may transcend traditional diagnostic boundaries.

Hormonal fluctuations shape learning through changes in dopamine signaling

Researchers have long established that hormones significantly affect the brain, creating changes in emotion, energy levels, and decision-making. However, the intricacies of these processes are not well understood.

Stress-induced neuron loss shown to disrupt blood flow and neural communication

While the exact causes of neurodegenerative brain diseases like Alzheimer's and dementia are still largely unknown, researchers have been able to identify a key characteristic in affected brains: reduced blood flow.

Hearing loss in infancy linked to disrupted brain organization and language pathways

Infants born deaf or hard of hearing show adverse changes in how their brains organize and specialize, but exposure to sound and language may help them develop more normally, according to new research.

Innovative control strategy enhances stroke rehabilitation with CASIA-EXO exoskeleton

Stroke is one of the leading causes of non-traumatic disability worldwide, affecting more than 15 million people each year, with about three-quarters experiencing long-term functional impairments.

The caffeine conundrum in rapid depression treatments

Perhaps the most intriguing implication of recent breakthrough research lies in an unexpected connection: the most rigorous mechanistic dissection of rapid antidepressant action identifies adenosine as the critical mediator, yet adenosine receptors are the primary target of caffeine, the world's most widely consumed psychoactive substance.

Study reveals how neural excitability and learning potential fluctuate across the day

Our brains do not react in a fixed, mechanical way like electronic circuits. Even if we see the same scene every day on our commute to work, what we feel - and whether it leaves a lasting impression - depends on our internal state at that moment.

Amyloid-clearing drug fails to change waste clearance function in the brains of Alzheimer's patients

A group from Osaka Metropolitan University in Japan, led by graduate student Tatsushi Oura and Dr. Hiroyuki Tatekawa, found that treatment using the drug lecanemab to remove amyloid plaques in the brain does not change the waste clearance function in the brains of Alzheimer's disease (AD) patients in the short term.

Midlife blood test may reveal Alzheimer’s disease risk in advance

A simple blood test for platelet activity at middle age could one day help identify people at risk for Alzheimer's disease decades ahead of time, allowing for possible preventive therapy.

Shared genetic roots connect neurological and psychiatric disorders

In a groundbreaking study, researchers from the Centre for Precision Psychiatry at the University of Oslo and Oslo University Hospital have discovered extensive genetic links between neurological disorders like migraine, stroke and epilepsy, and psychiatric illnesses such as schizophrenia and depression.

Targeting RNA splicing errors protects against tau-induced neurodegeneration

Alzheimer's Disease (AD), the leading cause of dementia, affects nearly 40 million individuals globally, resulting in a gradual loss of memory and independence. Despite extensive research over the past decades, no treatments have been found that can halt or reverse the progression of this devastating disease.

Anticoagulants increase bleeding post-ablation with no added stroke benefit

A minimally invasive heart procedure to correct irregular heart rhythms called catheter ablation may reduce the risk of stroke enough that some patients can discontinue blood thinners, according to a preliminary late-breaking science presentation today at the American Heart Association's Scientific Sessions 2025.

Preclinical study reveals dampened neuronal activity in alcohol-exposed mice

A psychedelic found in mushrooms is emerging as a potential treatment for alcohol use disorders. This possibility is due to a compound the body converts the psychedelic into called psilocin, but psilocin's mechanisms remain unclear.
