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.

Novel MRI contrast agent offers hope for early detection of Alzheimer’s disease

Hong Kong Baptist University scientists have invented a novel contrast agent for magnetic resonance imaging, which enables real-time visualization and detection of the size and number of amyloid-beta in the brain, a main hallmark of Alzheimer’s disease.

SARS-CoV-2 virus may target red marrow and prevent the formation of new erythrocytes

Specialists from the Department of Fundamental Medicine of Far Eastern Federal University (FEFU) with Russian and Japanese colleagues have probed into mechanisms of COVID-19 inside-the-body distribution linked to erythrocytes damaging.

Children with minor perinatal brain bleeds have normal cognitive development at two years of age

In 2007, UNC researchers published unexpected and surprising results from a study based on magnetic resonance imaging (MRI) of newborn brains.

Neuroscientists show how the brain manages to adapt in people born without a corpus callosum

One in 4,000 people is born without a corpus callosum, a brain structure consisting of neural fibers that are used to transfer information from one hemisphere to the other.

The road to achieving single molecular spectroscopy using nanoIR

In this interview, Francesco Simone Ruggeri from the University of Cambridge talks to News-Medical Life Sciences about their research into biomolecules and the methods that are helping to achieve spectra at the single-molecule scale.

Addictive drug displays different acute pharmacology and synaptic plasticity

Nucleus accumbens in the brain play a central role in the risk-reward circuit. Their operation is based chiefly on three essential neurotransmitters: dopamine, which promotes desire; serotonin, whose effects include satiety and inhibition; and glutamate, which drives goal-directed behaviors and responses to reward-associated cues and contexts.

SARS-CoV-2 spike proteins can directly impact the blood-brain barrier

Like a key, SARS-CoV-2 - the virus that causes coronavirus disease 2019 (COVID-19) - attaches to specific molecules on the host cell surface, opening gateways into the cell interior.

Study shows statins can have adverse effects on certain organs

600,000 Danes take medicine containing statins. Statins lower the cholesterol level and thus helps prevent cardiovascular disease and blood clots.

Researchers identify distinct link between autism and brain cell abnormalities

Johns Hopkins Medicine researchers report that new experiments with genetically engineered mice have found clear connections among a range of autism types and abnormalities in brain cells whose chemical output forges platonic (non-sexual) feelings of love and sociability.

RNI researchers to study the impact of excessive speeds on the human brain, body

Before the first Virgin Hyperloop ride takes off, the brains behind pioneering neuroscience research at West Virginia University will help ensure the health and well-being of its passengers and operators.

Social threat can change a specific brain region

Our brains are wired to protect us from threats. For social animals like humans, threats often come from other members of our own species when there is conflict over food, mates, or territory.

Study sheds new light on the biological base of psychotic symptoms

Anti-NMDAR encephalitis is an autoimmune brain illness that is often mistaken by a psychiatric disorder since it causes psychoses and other behaviour alterations. Despite having these similarities, the illness does not respond to common antipsychotic treatments.

MD65 IgG-YTE shows powerful post-exposure neutralization of SARS-CoV-2

A recent study published in the preprint server bioRxiv in October 2020 describes a reliable animal model to demonstrate the powerful capacity of human neutralizing mAbs directed against SARS-CoV-2 to prevent viral binding the host cell receptor and thus block infection. This indicates the lifesaving value of mAbs in severe COVID-19.

Study reveals how gene control mechanisms define the identity of developing brainstem neurons

A recent study at the University of Helsinki reveals how gene control mechanisms define the identity of developing neurons in the brainstem.

Study suggests a role for the hypothalamus in genetic susceptibility to IBD

Using sophisticated 3D genomic mapping and integrating with public data resulting from genome-wide association studies, researchers at Children's Hospital of Philadelphia have found significant genetic correlations between inflammatory bowel disease and stress and depression.

Intercellular communication pathway drives motivation to seek cocaine

In the October 28, 2020 issue of the Journal of Neuroscience, researchers from the Medical University of South Carolina and the National Institutes of Health describe how reminders of drug use can change specific brain cells responsible for motivation, increasing the desire to seek drugs.
