From the black-and-white days of I Love Lucy to the blue-ray lasers of today’s Game of Thrones in dazzling 3D, parents have worried that television might harm their child’s brain development. Now the answer is plain to see. Brain imaging (MRI) shows anatomical changes inside children’s brains after prolonged TV viewing that would lower verbal IQ. Continue reading
The disastrous earthquake in Kathmandu has killed hundreds of people and brought grievous tragedy to thousands. Even among the survivors, the earthquake will leave its mark in the form of altered brain structure, according to neuroimaging research performed on survivors of the Wenchuan earthquake of 2008.
A fascinating report on NPR by science correspondent Jonathan Hamilton yesterday (March 16, 2015) tells the story of Jonathan Keleher, a rare individual born with a major portion of his brain missing: the cerebellum. The name in Latin means “little brain,” because the cerebellum sits separately from the rest of the brain looking something like a woman’s hair bun. Neuroscientists have long understood that the cerebellum is important for controlling bodily movements, by making them more fluid and coordinated, but researchers have also long appreciated that cerebellum does much more. Exactly what these other functions are, have always been a bit mysterious.
Felipe de Brigard is an Assistant Professor of Philosophy, Arts & Sciences at Duke University. His research, at the intersection of philosophy, psychology and neuroscience, explores the neural mechanisms of false memories and consciousness. He joined us to discuss the nature of memory and the hard problem of consciousness. Continue reading
On January 11, 2015 news swept the globe reporting that scores of people died and 200 were sickened by drinking beer poisoned with crocodile bile in Mozambique. Thinking is now shifting to the possibility of poisoned synapses, not reptilian bile as the cause of these deaths.
In the eerie science fiction film, Under the Skin, starring Scarlett Johansson as an alien vixen clothed in human skin, roaming the earth in search of single men for nefarious purposes, a turning point comes when she offers a hooded man on a dark road a ride in her vehicle. When the man takes off his hood we see his shockingly disfigured face. It is not make up. The disfigurement is caused by a genetic condition, neurofibromatosis, affecting actor Adam Pearson. Pearson’s brother has the same disorder, but no disfigurement. Instead he suffers memory problems. The film is a head scratcher–in the best possible way–but neurofibromatosis is not. Let’s have a look.
As we turn the page on 2014, here’s a list of some of the year’s highlights in neuroscience – along with a heavy dose of speculation about what they might mean for the future of the brain.
