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.
The lack of some genes in the BEC/TCEAL cluster could be related to some alterations associated with the autism spectrum disorder, according to a preclinical study published in the journal Genome Biology, and led by Professor Jordi Garcia Fernàndez, from the Faculty of Biology and the Institute of Biomedicine of the University of Barcelona (IBUB), and researcher Jaime Carvajal, from the Andalusian Centre for Developmental Biology - University Pablo de Olavide (CSIC-UPO).
Multiple sclerosis (MS) is an autoimmune disorder that develops as immune cells attack the nervous system. T cells are a critical part of our immune system, with a complex array of subtypes - some drive the autoimmune response, while others try to suppress it.
Research from Saint Louis University finds that high fat or "ketogenic" diets could completely prevent, or even reverse heart failure caused by a metabolic process.
Actin is among the most abundant proteins in cells, and it has many jobs--from giving the cell its very shape and structure to managing networks of proteins crucial to numerous cellular functions. Without it, the fragile fundamental unit of life would crumble.
According to a study, DNA variation in a gene is linked to early anatomical variations in a region of the brain that plays a crucial role in quantity representation.
A team of researchers have discovered that a gut hormone, called ghrelin, is a crucial regulator of new nerve cells that form in the adult brain.
Based on digital endocranial cast models the canine brain does not increase proportionally with body size. Researchers at ELTE Eötvös Loránd and Kaposvár University in Hungary reconstructed the surface morphology of 28 canine brains, including various dog breeds, wolves, coyotes, and jackals.
A metabolite produced following consumption of dietary soy may decrease a key risk factor for dementia--with the help of the right bacteria, according to a new discovery led by researchers at the University of Pittsburgh Graduate School of Public Health.
New research shows a simple skin test can accurately identify Parkinson's disease, demonstrating for the first time the feasibility of the method. Currently diagnosed by clinical signs and symptoms but only definitively diagnosed at autopsy, Parkinson's disease is commonly misdiagnosed early in the disease course, complicating clinical trials of potential treatments.
For many cancers, doctors are increasingly looking to the DNA that solid tumors shed into the blood stream to help with diagnosis and monitoring.
Scientists have made it simple for researchers to interpret biological processes all by making a small change to the color palette.
In a National Institutes of Health (NIH)-funded study involving both mice and patients who are part of an NIH Clinical Center trial, researchers discovered that a gene, called PIEZO2, may be responsible for the powerful urge to urinate that we normally feel several times a day.
Spotting, pursuing and catching prey - for many animals this is an essential task for survival. Scientists at the Max Planck Institute of Neurobiology now show in zebrafish that the localization of neurons in the midbrain is adapted to a successful hunting sequence.
During metastasis, cancer cells actively interact with microenvironments of new tissues. How metastatic cancer cells respond to new environments in the secondary tissues is a crucial question in cancer research but still remains elusive.
Researchers have designed a laboratory test that can precisely examine the deadliest cells found in the most common and aggressive type of brain cancer.
People who experienced childhood trauma usually suffer lifelong consequences that impact their physical and mental health.
Drugs of abuse, like cocaine, are so addictive due in part to their cellular interaction, creating strong cellular memories in the brain that promote compulsive behaviors.
A team co-led by scientists at Scripps Research has found that the main sensor protein enabling our sense of touch also underlies the feeling of having a full bladder and makes normal bladder function possible.
Researchers at Linköping University, Sweden, have discovered a new mechanism by which substances can open a certain type of ion channel and in this way regulate nerve impulses.
Variations in a gene that regulates dopamine levels in the brain may influence the mobility of elderly and frail adults, according to new research from the University of Pittsburgh Graduate School of Public Health.
