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.

MRI scans reveal human brain growth from pregnancy through birth

Analyzing brain growth across pregnancy and early life, this study offers new insights into sex-specific development and its implications for neurodevelopment.

New score predicts complications after mild traumatic brain injury

A study led by researchers at the Institute for Research in Biomedicine of Lleida (IRBLleida), the University of Lleida (UdL), the Universitat Oberta de Catalunya (UOC) and Arnau de Vilanova University Hospital (HUAV) has developed and internally validated a clinical prediction model called the Goliat score, which can be used by emergency services to estimate the risk of acute complications in patients suffering from minor and moderate traumatic brain injuries (TBIs).

A common diabetes drug may prevent long COVID when taken early

Research supports metformin's efficacy in reducing long COVID symptoms, suggesting its use in acute COVID-19 cases could alleviate long-term health impacts.

Aging alters social preferences through distinct brain mechanisms

The loss of social connectedness as people age increases the odds of cognitive-related disorders and can worsen health outcomes in older populations. But is there a direct relationship between social behavior and cognition? Subhadeep Dutta Gupta, Peter Rapp, and colleagues, from the National Institute on Aging, developed a rat model to probe social cognition in the aging brain.

New liquid biopsy detects early cancers through epigenetic instability

Researchers at the Johns Hopkins Kimmel Cancer Center have developed a novel liquid biopsy approach to identify early-stage cancers by measuring the random variation in DNA methylation patterns, rather than the absolute level of those patterns as in other liquid biopsies.

Study finds five distinct human sleep chronotypes

The familiar labels "night owl" and "early bird," long used in sleep research, don't fully capture the diversity of human internal clocks, a new study has found.

Aging brains struggle to recycle synaptic proteins

As we age, we begin to lose the connections that wire up our brains-and neuroscientists aren't sure why.

Mouse study reveals mechanism driving first night insomnia

You check into a hotel and toss and turn all night, but your sleep improves the following night. Scientists at Nagoya University wanted to understand why this happens.

Exploring how prenatal alcohol and stress affect rhesus monkey offspring in adulthood

New in JNeurosci, Mary Schneider and Alexander Converse, from the University of Wisconsin-Madison, led an interdisciplinary study to explore how prenatal alcohol and stress exposure affect rhesus monkey offspring in adulthood.

Playing pink noise during sleep could be harmful for children

Pink noise-often used to promote sleep-may reduce restorative REM sleep and interfere with sleep recovery.

Targeted therapy for the less impaired arm improves movement for stroke survivors

Traditional stroke rehabilitation therapy focuses on restoring strength and movement to the more impaired side of the body, but a new randomized clinical trial has revealed that targeted therapy for the less impaired arm significantly improved movement and control for stroke survivors.

Blood gene signals reveal Parkinson’s risk years before diagnosis

Blood-based DNA repair and stress-response signals reveal early molecular changes in Parkinson's disease, aiding in potential early diagnosis and intervention.

Regulating microglial phagocytosis through immunotherapy could slow Parkinson's disease progression

By analyzing tissue from patients with Parkinson's disease, and animal and cellular models of the disease, a research team from the Institut de Neurociències of the UAB has shown that the main immune cells of the brain become reactive and overexpress certain receptors that promote the elimination of dopaminergic neurons, even when these neurons are still functional.

Do lifestyle choices affect university students' grades

Researchers examine the association between academic performance on secondary school exams and lifestyle behaviors among university students.

Researchers open ‘window to the brain’ with powerful cancer tech

Technology created at The University of Queensland could improve the odds of surviving brain cancer and change how we treat a range of neurological conditions.

Chlamydia pneumoniae found in the eye may aggravate Alzheimer’s disease

Chlamydia pneumoniae—a common bacterium that causes pneumonia and sinus infections—can linger in the eye and brain for years and may aggravate Alzheimer’s disease, according to a study from Cedars-Sinai.

Distinct tau chemical signatures redefine diagnosis across neurodegenerative diseases

Tau protein aggregation is a shared feature in over 20 neurodegenerative diseases (collectively referred to as "tauopathies"). New research led by Boston Children's Hospital challenges the current "one-size-fits-all" approach to diagnosing and treating these tauopathies.

Genetic ancestry influences tumor biology and survival in head and neck cancers

Genetic ancestry plays a key role in determining the behavior of head and neck tumors and may help explain why African-American patients survive for half as long as their counterparts of European ancestry, according to a new review study led by researchers from the University of Maryland School of Medicine's (UMSOM) Institute for Genome Sciences (IGS) and the University of Maryland Greenebaum Comprehensive Cancer Center (UMGCCC).

Study offers hope for preventing hydrocephalus in children

Hydrocephalus is a life-threatening condition that occurs in about 1 in 1,000 newborns and is often treated with invasive surgery. Now, a new study offers hope of preventing hydrocephalus before it even occurs.
