Inside The Language Brain

Why is it that humans can speak but chimpanzees, our closest living relatives, cannot?

The human brain is uniquely wired to produce language. Untangling this wiring is a major frontier of brain research. Peer into the mental machinery behind language with this feature video, which visits a brain-scanning laboratory—Columbia University’s Program for Imaging and Cognitive Sciences.

Columbia neuroscientist Joy Hirsch and New York University psychologist Gary Marcus explain what researchers have learned about how our brain tackles language—and what’s left to learn.

Awakening from anesthesia is often associated with an initial phase of delirious struggle before the full restoration of awareness and orientation to one’s surroundings. Scientists now know why this may occur: primitive consciousness emerges first.

The first atlas of the surface of the human brain based upon genetic information has been produced by a national team of scientists, led by researchers at the University of California, San Diego School of Medicine and the VA San Diego Healthcare System. The work is published in the journal Science.

Researchers help reveal complex role of genes in autism.

New research from scientists at the University of Milan considers the complications and new treatment challenges for elderly patients who suffer traumatic brain injury as a result of a fall.

Investigators from the University of Amsterdam, Netherlands, have shown that in most elderly patients invasive and expensive techniques, i.e. lumbar puncture and PET scan, are not useful to establish the diagnosis of Alzheimer’s disease.

Sleep plays a powerful role in preserving our memories. But while recent research shows that wakefulness may cloud memories of negative or traumatic events, a new study has found that wakefulness also degrades positive memories. Sleep, it seems, protects positive memories just as it does negative ones, and that has important implications for the treatment of post-traumatic stress disorder.

Inside the teenage brain

In this brain video Dr. Greg Berns talks about a new study using brain imaging to study teen brain development. It turns out that adolescents who engage in dangerous activities have frontal white matter tracts that are more adult in form than their more conservative peers.
