Neuronal activity in the visual cortex controlled by both where the eyes are looking and what they see
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 ...

The thermodynamics of thought: Soliton spikes and Heimburg-Jackson pulses
(Medical Xpress)—In the familiar rendering of a neuron, as in the image above, the so-called electrical spikes are usually depicted as short pulses. In reality, if the spike lasts for over a millisecond and its expanding ...
