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.

Having a sense of purpose linked to lower dementia risk

Research into Blue Zones - regions of the world where people tend to live longer - shows that having a sense of purpose in life may help people live longer.

Research uncovers key role of the brain's blood flow dynamics in Alzheimer’s disease

Over seven million Americans are living with Alzheimer's disease (AD) and the heartbreaking day-to-day battle with the effects of cognitive decline.

Can diet alone slow brain aging? Scientists say evidence is still too weak

Researchers reviewing evidence in the Annual Review of Nutrition find that healthy dietary patterns may support brain aging, but caution that scientific enthusiasm currently outpaces solid proof. Multidomain strategies combining diet with exercise, cognitive training, and vascular health show greater promise.

Engineering digital twins to transform diagnosis and treatment for GI disorders

For many people, gastrointestinal (GI) disorders are chronic and life-altering conditions. Yet despite their prevalence, doctors are often challenged by patients experiencing persistent symptoms with no way to accurately identify and diagnose diseases.

Study identifies key metric for safe blood brain barrier opening in glioblastoma patients

Researchers found that acoustic emission dose-an acoustic signal from microbubbles-could predict how to adjust ultrasound power and open the blood brain barrier for delivering drugs in patients with glioblastoma.

History of traumatic brain injury tied to greater chance of malignant brain tumors

New research led by investigators at Mass General Brigham suggests a link between a history of traumatic brain injury (TBI) and risk of developing a malignant brain tumor.

New study reveals long road to seizure control for people with focal epilepsy

Antiseizure medications help the majority of people with focal epilepsy, a common form of the neurological disorder.

Positive emotion bias in aging may signal cognitive decline

As people age, they display a bias in recognizing emotions as positive-to the point of improperly labeling neutral or negative emotions as positive.

Neural signature reveals how self-preoccupation manifests in the brain

People tend to be self-preoccupied. Self-interest is good when it ensures that one's needs are met, but it can also be maladaptive; research shows that the tendency to self-focus promotes the occurrence of depression and anxiety and can even prolong these conditions.

Scientists discover molecular brake that halts brain cell repair in multiple sclerosis

A team of scientists led by the Institute for Glial Sciences (IGS) at Case Western Reserve University's School of Medicine has discovered a built-in "brake" that controls when key brain cells mature.

Groundbreaking approach combines 3D printing and stem cell biology for spinal cord injury recovery

For the first time, a research team at the University of Minnesota Twin Cities demonstrated a groundbreaking process that combines 3D printing, stem cell biology, and lab-grown tissues for spinal cord injury recovery.

Food choices may depend more on blood sugar than body weight

Maybe you shouldn't always listen to your gut. Researchers at the Fralin Biomedical Research Institute at VTC recently studied flavor-nutrient learning - how people come to prefer certain food based on how it makes them feel.

Shame linked to lower quality of life in people with gut disorders

Feelings of shame are linked to reduced quality of life - as shown by the first study to measure shame as a factor influencing the connection between chronic gastrointestinal disorders and mental health.

Mind wandering may hold key to better ADHD diagnosis in adults

Only a few decades ago, it was believed that ADHD was something one outgrew during adolescence. However, about half of those diagnosed at a young age carry it into adulthood.

How a single gene reshapes pain perception through polyamine signaling

Researchers have identified SLC45A4 as a neuronal polyamine transporter genetically linked to human chronic pain. Loss of this gene in mice disrupts polyamine balance, alters spinal GABA levels, and reduces heat and tonic pain sensitivity.

Study shows brain keeps internal body map intact after amputation

Researchers tracked brain activity before and after arm amputation and found that hand and lip maps in the cortex remained remarkably stable for up to five years. This challenges decades-old assumptions of large-scale remapping and supports the idea of a resilient internal body model.
