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.

Lab on a chip mimics chemical complexities of the brain

Johns Hopkins researchers from the Whiting School of Engineering and the School of Medicine have devised a micro-scale tool - a lab on a chip - designed to mimic the chemical complexities of the brain.

Discovery of 'overdrive' protein could broaden drug design options

New research by scientists at the University of North Carolina at Chapel Hill shows for the first time that an important family of proteins known to function at the cell surface also functions at a site within the cell.

Some cases of autism may be traced to the immune system of mothers during pregnancy

New research from the UC Davis M.I.N.D. Institute and Center for Children's Environmental Health has found that antibodies in the blood of mothers of children with autism bind to fetal brain cells, potentially interrupting healthy brain development.

Prion infection of neurons increases the free cholesterol content in cell membranes

A new study published in the online open access journal BMC Biology suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause neurodegeneration and could point to a role for cholesterol in other neurodegenerative diseases.

Prenatal exposure to maternal antibodies linked to autistic behaviors in offspring

New research from the UC Davis M.I.N.D. Institute shows that an interaction between fetal brain cells and maternal antibodies could be linked with the repetitive behavior - also called stereotypies - that is characteristic of autism.

Learning disabilities associated with language problems later in life

Individuals with a neurodegenerative condition affecting language appear more likely to have had a history of learning disabilities than those with other types of dementia or with no cognitive problems, according to a report in the February issue of Archives of Neurology.

Evolving complexity out of junk DNA

The study, published in Proceedings of the National Academy of Sciences, USA, claims to have solved this scientific riddle by analysing the genomics of primitive living fishes such as sharks and lampreys and their spineless relatives, such as the sea squirts.

Staging mock cardiac and respiratory arrests expose weaknesses in hospital emergency response for children

Staging mock cardiac and respiratory arrests - "code" situations in hospital parlance - easily expose common failures in rapid response with CPR and other life-saving care for children and also set up powerful incentives to sharpen emergency skills and move fast to use them, suggests a study from the Johns Hopkins Children's Center.

Oxytocin hormone promotes bonding

Gazing into your lover's eyes isn't only romantic; it may also mimic early attachments that forever alter your brain and body.

New insight into how iron gets deposited in the brain to cause some forms of Parkinson's and Alzheimer's

Researchers at the University of Warwick and the Indian Institute of Technology Kanpur have discovered that the mechanism that we rely on to transport iron safely through our blood stream can, in certain circumstances, collapse into a state which grows long worm-like "fibrils" banded by lines of iron rust.
