Preclinical study shows aged garlic extract improves memory and reduces anxiety

Long-term aged garlic extract supplementation improved specific anxiety-related behaviors and enhanced memory and learning in aging mice. Proteomic profiling revealed extensive hippocampal and cortical molecular changes linked to synaptic signaling, neuroplasticity, and stress-response pathways.

Mental navigation framework helps people change pathological thinking

The stereotypical image of psychotherapy shows a patient lying on a couch, exploring their deepest traumas. This leads to awareness of unconscious habits, thoughts, and drives and has long been a cornerstone of psychotherapy.

How soccer fandom rewires the brain

Studying brain patterns in soccer fans, researchers found that certain circuit regions of the brain were activated while viewing soccer matches involving their favorite team, triggering positive and negative emotions and behaviors, according to a new study published today in Radiology, a journal of the Radiological Society of North America (RSNA).

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.

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.

Study finds reduced cortical choline levels in people with anxiety disorders

People with anxiety disorders have lower levels of choline in their brains, according to research from UC Davis Health.

Mapping the brain's body regulation and sensing system using 7 Tesla MRI

Jiahe Zhang, PhD, of the Department of Psychiatry at Mass General Brigham, is the lead author of the paper published in Nature Neuroscience, "Cortical and subcortical mapping of the human allostatic-interoceptive system using 7 Tesla fMRI."

5,000 steps a day may slow Alzheimer’s-related brain changes

Regular walking is linked to slower cognitive decline in older adults, emphasizing its role in delaying Alzheimer’s disease and enhancing memory retention.

Newly identified microglia subtype offers protection against Alzheimer’s disease

In Alzheimer's disease, the leading cause of dementia, microglia-the brain's immune defenders-can act as both protectors and aggressors, shaping how the disease progresses.

Aggression and self-harm could share a common neural basis

Aggression and self-harm often co-occur in individuals with a history of early-life trauma-a connection that has largely been documented by self-reporting in research and clinical settings.

USC researchers map genetic architecture of the human corpus callosum

For the first time, a research team led by the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC has mapped the genetic architecture of a crucial part of the human brain known as the corpus callosum-the thick band of nerve fibers that connects the brain's left and right hemispheres.

Study uncovers neural mechanisms behind memory stabilization

Newly decoded brain circuits make memories more stable as part of learning, according to a new study led by NYU Langone Health researchers.

Study finds more commonalities between CTE and Alzheimer's disease at the genetic level

Chronic traumatic encephalopathy (CTE) – most often found in athletes playing contact sports – is known to share similarities with Alzheimer's disease (AD), namely the buildup of a protein called tau in the brain.

Football hits leave lasting brain changes

Recent MRI research reveals how repeated football head impacts reshape brain structures, offering insights into chronic traumatic encephalopathy (CTE) risk.

Study links short-term blood pressure variability to Alzheimer's-related brain loss

Even when blood pressure is well controlled, older adults whose blood pressure fluctuates widely from one heartbeat to the next may be at greater risk for brain shrinkage and nerve cell injury, according to a new study led by the USC Leonard Davis School of Gerontology.

Systematic analysis reveals psilocybin's impact on obsessive-compulsive behaviors

A systematic review published today in Psychedelics by Mr. James Gattuso and colleagues at the Florey Institute of Neuroscience and Mental Health synthesizes clinical and preclinical evidence on psilocybin's effects on obsessive-compulsive behaviors, revealing consistent therapeutic potential across human patients and validated animal models.
