Researchers have shed new light on how cells called gliomas migrate in the brain and cause devastating tumors. The findings, published in Nature Communications, show that gliomas — malignant glial cells — disrupt normal neural connections and hijack control of blood vessels.
New details on the NMDA receptor could aid development of drugs for Alzheimer’s, Parkinson’s, depression, other neurological disorders.
In a new study, scientists took a molecular-level journey into microtubules, the hollow cylinders inside brain cells that act as skeletons and internal highways. They watched how a protein called tubulin acetyltransferase (TAT) labels the inside of microtubules. The results, published in Cell, answer long-standing questions about how TAT tagging works and offer clues as to why it is important for brain health.
Patients with persistent ringing in the ears – a condition known as tinnitus – process emotions differently in the brain from those with normal hearing, researchers report in the journal Brain Research.
Pornography triggers brain activity in people with compulsive sexual behaviour – known commonly as sex addiction – similar to that triggered by drugs in the brains of drug addicts, according to a University of Cambridge study published in the journal PLOS ONE. However, the researchers caution that this does not necessarily mean that pornography itself is addictive.
Around half of the genes that influence how well a child can read also play a role in their mathematics ability, say scientists from UCL, the University of Oxford and King’s College London who led a study into the genetic basis of cognitive traits.
Psychologists at Stony Brook University, NY, suggest that about 20% of the population are genetically predisposed to be more aware and empathic. Now, in a new study, they explore which regions of the brain are implicated in this. They publish their findings in the journal Brain and Behavior.
Learning a second language may help improve brain function regardless of when you start, according to a new study.
