Eye cells may use math to detect motion

In a study of mice, scientists showed how one type of neuron in the eye may distinguish moving objects. The study suggests that the NMDA receptor, a protein normally associated with learning and memory, may help neurons in the eye and the brain relay t…

Dementia plaques attack language center of brain

The recent ability to peer into the brain of living individuals with a rare type of language dementia, primary progressive aphasia, provides important insight into the beginning stages of this disease, when it is caused by a buildup of a toxic protein …

Discovery identifies new treatment target for age-releated macular degeneration, Alzheimer’s

For the first time, researchers have shown that a protein critical to the body’s ability to remove waste products from the brain and retina is diminished in age-related macular degeneration, after first making the discovery in an Alzheimer’s disease br…

Songbirds pinpoint effects of Huntington’s disease

Scientists have parsed the role of the Huntington’s disease gene in an area of the songbird’s brain responsible for complex, sequential movements. These findings not only give a clearer view of how the genetic mutation that causes Huntington’s disease …

Talk about yourself on social media?

A network of brain regions involved in self-disclosure on Facebook has been determined by a team of researchers. In the first study to examine the intrinsic functional connectivity of the brain in relation to social media use, researchers observed conn…

Toxic byproduct of hemoglobin could provide clues for cerebral hemorrhage and Creutzfeldt-Jakob Disease

A novel mechanism has been found that could protect the brain from damage due to stroke and a variety of neurodegenerative conditions, including sporadic Creutzfeldt-Jakob disease, Alzheimer’s disease, and Parkinson’s disease, report scientists.

Scientists map roots of premeditated, violent ‘intent’ in animal brain

The bad intentions that often precede violence originate in a specific brain region, according to a study in mice. The work is the first, say the study authors, to tie warning signs of premeditated violence — stalking, bullying, and possibly sexual ag…

Brain region responsible for violence identified

Researchers have pinpointed the brain area in male mice responsible for aggression and say their work could lead to ‘controlling aggressive behaviors.’

Depression, anxiety may reduce chances of IVF pregnancy

Depression and anxiety, and not necessarily the use of antidepressant medication, are associated with lower pregnancy and live birth rates following in vitro fertilization, according to a large register study in Sweden. The findings will be of interest…

Scientists tap the smarts of mice, capture problem-solving in action

Scientists have captured unique images of problem-solving in action by tapping into the minds of mice. The study shows rapid rewiring in the frontal brains of mice after they learn by trial and error.
