(Medical Xpress)—One way to increase our understanding of bilateral brains, like our own, is to inspect their paired sensory systems. In our visual system, the optic nerves normally combine at a place called the optic chiasm. ...
(Medical Xpress)—The smooth operation of the brain requires a certain robustness to fluctuations in its home within the body. At the same time, its extraordinary power derives from an activity structure poised at criticality. ...
A Weizmann Institute experiment in which volunteers learned to sense objects' locations using just "rat whiskers" may help improve aids for the blind.
