The brain receives information from the ear in a surprisingly orderly fashion, according to a University at Buffalo study scheduled to appear June 6 in the Journal of Neuroscience.

Magnetic stimulation to improve visual perception
(Medical Xpress) — Using transcranial magnetic stimulation (TMS), an international team led by French researchers from the Centre de Recherche de l’Institut du Cerveau (CNRS) has succeeded in enhancing the visual abilities of a group of healthy subjects. Following stimulation of an area of the brain’s right hemisphere involved in perceptual awareness and in orienting spatial attention, the subjects appeared more likely to perceive a target appearing on a screen. This work, published in the journal PLoS ONE, could lead to the development of novel rehabilitation techniques for certain visual disorders. In addition, it could help improve the performance of individuals whose tasks require very high precision.
A different drummer: Neural rhythms drive physical movement
Unlike their visual cousins, the neurons that control movement are not a predictable bunch. Scientists working to decode how such neurons convey information to muscles have been stymied when trying to establish a one-to-one relationship between a neuron’s behavior and external factors such as muscle activity or movement velocity.
Diabetes drug could be a promising therapy for traumatic brain injury
Although the death toll is relatively low for people who suffer from traumatic brain injury (TBI), it can have severe, life-long consequences for brain function. TBI can impair a patient’s mental abilities, impact memory and behavior, and lead to dramatic personality changes. And long-term medical treatment carries a high economic cost.
Researchers restore neuron function to brains damaged by Huntington’s disease
Researchers from South Korea, Sweden, and the United States have collaborated on a project to restore neuron function to parts of the brain damaged by Huntington’s disease (HD) by successfully transplanting HD-induced pluripotent stem cells into animal models.
