(Medical Xpress)—Neurophysiologist like to think of neurons as communicating with spikes. If that were the whole story, it might be possible to imagine spike codes which could then be used to estimate the flow of information, ...
Even though our eyes are constantly moving, the brain perceives the external world as stationary—a feat achieved by integrating images acquired by the retina with information about the direction of the gaze. An international ...
