To translate touch, the brain can quickly rearrange its sense of the body

...y position. The observations showed that abnormal input into one of the body's sensory systems produced a rapid and profound change in another sensory system: The brain had changed the way it interpreted the signals from the sense of touch. These links between different bodily senses show that the brain c...

Study shows humans have ability to track odors, much like bloodhounds

...much the way it can localize sounds by contrasting input from the ears. "It has been very controversial whether humans can do egocentric localization, that is, keep their head motionless and say where the spatial source of an odor is," said study coauthor Noam Sobel, associate professor of psychology at U...

Hopkins AIDS experts issue warning about global efforts to provide drug therapies

...he worst-case scenario, even a plan with no public input can backfire if it fails to win local support," says McGough, a research fellow at Hopkins' Institute of the History of Medicine. "It is as important to make sure that the decision-making body is politically legitimate and accountable to the public a...

Brain May Be Less Plastic Than Hoped

...after these areas fell silent from lack of sensory input due to injury. This led to speculation that adult brains could compensate for permanent damage to the eyes, ears, skin, or even to itself. In the case of damage to the retina, Smirnakis said, “the predominant-but by no means universal-view was that s...

Alzheimer's cognitive decline slowed

... in most cortical regions that receive cholinergic input from forebrain nerve cells called the nucleus basalis, and in the cerebellum, a structure associated with cortical plasticity. In addition to Tuszynski, authors of the paper in Nature Medicine, were Leon Thal, M.D., UCSD chair of neurosciences, dire...

Glow-in-the-dark zebrafish at UH hold keys to biological clocks

...mined that it does take some sort of environmental input for the clock to start. In this case it was exposure to light/dark cycles after the fourth day of development, about the age when the fish start to swim and feed." The researchers used zebrafish (danio rerio) because they yield such a high output of...

Bird Brains Show How Trial and Error May Contribute to Learning

...or nidopallium). In the avian brain, LMAN receives input about complex movements from the basal ganglia and forwards the information to motor neurons that participate in song production. Without LMAN, scientists have long known, a young bird cannot learn its song, but an adult bird can sing its song withou...
