Weekly Neuroscience Update

When sound waves hit a sensory cell of the ear, they are converted into electrical nerve signals through specialized ion channels that open and close. Scientists at the University of Göttingen have now discovered a protein that is essential for the opening and closing of these ion channels. The protein could thus be responsible for the ability to hear.

High baseline levels of neuronal activity in the best connected parts of the brain may play an important role in the development of Alzheimer’s disease.

A team of researchers have developed a multidimensional set of brain measurements that, when taken together, can accurately assess a child’s age with 92 percent accuracy.

A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found.
