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.
A new study achieved the highest-ever resolution imaging of an infectious prion, offering atomic-level data of how these abnormal proteins assemble.
Cells produce exosomes, the nano-sized biological capsules, to protect and courier delicate molecules across the body. The capsules are hard enough to resist enzymatic breakdown and acidic and temperature fluctuations in the bloodstream and gut, which makes them a major candidate for drug delivery.
A research group has isolated monoclonal antibodies that, in laboratory and animal studies, prohibited infection by alphaviruses.
Scientists from the Icahn School of Medicine at Mount Sinai published the first of its kind research in the field of addiction genetics employing a multi-omics method to offer a huge list of causal candidate genes linked with alcohol consumption and alcohol use disorder (AUD).
Experimental research has shown that amyloid-beta, the Alzheimer’s protein, accumulates within nerve cells.
Recently, researchers discovered that a protein linked with Parkinson’s disease can impair mitochondria.
Proteins are the "tools" of our cells – they are essential to all vital tasks. However, they are only able to do their jobs if they fold correctly and adopt their respective, very specific 3D structure.
A gene called Npas4, already known to play a key role in balancing excitatory and inhibitory inputs in brain cells, appears to also be a master timekeeper for the brain's circadian clock, new research led by UT Southwestern scientists suggests.
Around 500,000 patients in China alone are considered to be living with a hereditary form of Alzheimer’s disease (AD).
Scientists, for the first time, developed a successful method for pinpointing proteins within different kinds of neurons in the brain of a living animal.
In a new study published in Nature today, Weizmann Institute of Science researchers, in collaboration with colleagues from the Hebrew University of Jerusalem, unveiled for the first time how three-dimensional space is represented in the mammalian cortex by the brain's "GPS" system.
Using data from two large, long-running study projects in the Puget Sound region -; one that began in the late 1970s measuring air pollution and another on risk factors for dementia that began in 1994 -; University of Washington researchers identified a link between air pollution and dementia.
Alzheimer’s disease (AD) is a neurological condition that leads to dementia worsening with age as patients show memory, cognitive, and psychological deficits.
According to scientists, people tend to prioritize food over sex after being deprived of both. The researchers examined this behavioral conflict in fruit flies.
Scientists have found that the brain lacks the ability to maintain the cholesterol-rich myelin sheath that insulates neurons when a protein is absent.
Chronic stress is a well-known cause for mental health disorders. New research has moved a step forward in understanding how glucocorticoid hormones ('stress hormones') act upon the brain and what their function is.
A new study has demonstrated the removal of damaged mitochondria from the brain cells of mice treated with a small molecule compound for Parkinson’s disease.
The cerebellum has been linked almost exclusively with motor control; however, research shows that it also contributes to numerous higher brain functions.
Scientists have come up with a method that enables the use of multi-focal images to reconstruct the movement of fast biological processes in 3D.
A group of scientists revealed a novel X-ray technique that allows control of neural function deep in the brain without causing any damage.
