Field effects in the CNS play functional roles

The functional role of the electrical inhibition is best understood in the context of the extremely short utilization time of the M-cell, as little as 400 μs, which serves to ensure survival by triggering a rapid escape (Catania, 2009). Within this very short interval two important computations must ...
