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.

Childhood lead exposure declines but disparities persist nationwide

Blood lead levels in young children in the United States declined in the last decade, but state data reveal that children of color and children from low-wealth families are still exposed to higher levels of lead, according to a new study in the American Journal of Public Health.

The cerebellum may help aging brains stay sharper

A large MRI study of more than 47,000 adults found that cerebellar aging is uneven, with posterior association regions and some motor-related areas showing steeper age-related changes. Larger cerebellar volumes were linked to better cognitive performance, supporting a threshold-reserve model in which the cerebellum may help sustain cognition before Alzheimer’s pathology becomes widespread.

Increased stress, reduced sleep alter brain structure and function in children

A new study suggests that variables linked to socioeconomic status (SES) – such as increased stress and reduced sleep – have strong relationships to brain structure and function in children.

Brain histamine neurons control moment-to-moment memory accessibility

The same memory can feel vivid and accessible one moment, yet stubbornly out of reach the next - even when the memory itself remains intact.

Genetic study links liver enzyme to compulsive cocaine addiction

Researchers at the University of California San Diego have completed a massive genetic study that identifies key biological drivers of cocaine addiction, uncovering a potential new target for treatment that resides in the liver rather than the brain.

Blood pressure control may be the key to optimizing stroke treatment after thrombectomy

Blood pressure management after thrombectomy for acute ischemic stroke may require a change in approach.

Circadian clock protein BMAL1 enhances inflammatory responses in immune cells

Daily life is shaped by the solar day, influencing when we wake up, eat, work, and sleep. Inside the body, a similar internal timing system -present in nearly every cell- known as the circadian clock, synchronizes many biological functions such as sleep, metabolism, hormone release, and even the immune system's activity.

Experts propose unified framework to advance the future of high-altitude medicine

As increasing numbers of people live, work, and travel at high altitudes, experts are calling for a major shift in how altitude-related health conditions are understood, diagnosed, and treated.

Teenage risk-taking linked to lower baseline dopamine levels

Teenage risk-taking, such as experimentation with alcohol, cannabis, nicotine and other substances, may reflect a compensatory response to lower baseline dopamine, the brain chemical for reward activity, suggests a new University of Pittsburgh School of Medicine study, published today in Nature Communications.

First-in-the-world gene therapy delivers missing gene directly to infant’s brain, marking historic milestone in precision medicine

An eight-month-old baby from Israel has become the first human ever to receive an experimental gene therapy designed to replace a missing gene responsible for a devastating neurological disease that until now offered no hope of survival.

A hidden immune pathway may help explain why Alzheimer’s inflammation persists

Researchers found that KAT7 promotes CMPK2-driven mitochondrial DNA release in microglia, activating inflammatory cGAS-STING and NLRP3 pathways linked to Alzheimer’s disease.

Scientists reveal how cGAS-STING fuels brain inflammation and neurodegeneration

The cGAS-STING pathway is emerging as a key driver of chronic neuroinflammation through its effects on glial activation, neuronal stress, blood-brain barrier integrity, and type I interferon signaling. The review highlights why selective, context-dependent modulation of cGAS-STING could help treat neurodegenerative diseases, while preserving its essential roles in antiviral defense and tumor surveillance.

Western diet weakens the gut’s nervous system through iron-dependent damage

A JCI study found that exposure to a Western diet in mice and to palmitic acid in murine and ex vivo human enteric nervous system models triggered ferroptosis, characterized by iron loading, lipid peroxidation, mitochondrial stress, and enteric neuronal loss. Boosting Nrf2 signaling protected enteric neurons and prevented Western diet-induced delayed colonic transit in mice, pointing to a potential pathway linking dietary fat exposure to gut motility dysfunction.

Low-methionine diet shows promise against aggressive brain tumors

An unexpected lab observation led a team of scientists to discover how diet can influence survival in animal models of glioma, one of the most aggressive and deadly forms of brain cancer.

Researchers identify genetic cause of severe childhood lung disease

A new report in the American Journal of Human Genetics describes a novel disorder caused by biallelic loss-of-function variants in the TMEM63B gene, which results in severe lung disease.

Many stroke patients miss intensive rehabilitation after hospitalization

Fewer than one in four people with stroke and fewer than one in seven people with traumatic brain injury receive inpatient rehabilitation care after being hospitalized, according to a study published on June 10, 2026, in Neurology Open Access, an official journal of the American Academy of Neurology.

Elevated blood pressure linked to lower dementia risk in people with physical frailty

For people with physical frailty, having high blood pressure may be associated with a lower risk of dementia, according to a study published on June 10, 2026, in Neurology®, the medical journal of the American Academy of Neurology.

Study links low vitamin C levels in the blood plasma to reduced brain connectivity

A study of 2,044 older Japanese adults found that those with lower vitamin C levels in their blood plasma tended to have a lower volume of gray matter in their brains, as well as lower connectivity amongst a collection of brain regions known as the default mode network.

New study maps early genetic disruptions in Rett syndrome

To better understand what drives the emergence of symptoms in Rett syndrome, researchers at Baylor College of Medicine and the Duncan Neurological Research Institute (Duncan NRI) at Texas Children's Hospital took a closer look at brain cells in mice modeling Rett syndrome before symptoms appeared.

New hybrid lens design drastically cuts 3D microscopy costs and complexity

A team led by Raju Tomer, professor of biological sciences at Columbia University, has created a new design for microscopes and microscope lenses that could push 3D tissue imaging beyond state-of-the-art systems while drastically cutting costs and complexity.
