Dendritic Computation - UCSD Cognitive Science

... of computation? We use a simple example to illustrate the problem. When one watches a movie, each frame is presented for about 50 ms, during which time we have to process any changes from the last frame before the next frame appears. To a first approximation the timescale of the computational cycle ...

Modulation of premotor circuits controlling locomotor activity by

... Locomotion is one of the most vivid expressions of the central nervous system in action. Looking at people walking in the street or the ballet dancer on the stage, motion seems effortless to the point that many movements are almost executed unconsciously. Indeed, the generation of sophisticated moto ...

Abstract: Primary afferent neurons rarely, if ever, synapse on the sympathetic preganglionic neurons that regulate the cardiovascular system, nor do sympathetic preganglionic neurons normally exhibit spontaneous activity in the absence of excitatory inputs. Therefore, after serious spinal cord injur ...

Neural engineering

Neural engineering (also known as neuroengineering) is a discipline within biomedical engineering that uses engineering techniques to understand, repair, replace, enhance, or otherwise exploit the properties of neural systems. Neural engineers are uniquely qualified to solve design problems at the interface of living neural tissue and non-living constructs.
