Paper Abstract

Neurons often display complex patterns of action potential firing in response to a wide variety of inputs. Correlations amongst the interspike interval sequence are often seen in experimental data from sensory neurons including electroreceptor afferents from weakly electric fish. Here we review some of our recent computational, theoretical, and experimental results on the mechanism by which negative interspike interval correlations increase information transfer: noise shaping. This mechanism might explain the behavioral hypersensitivity displayed by weakly electric fish when detecting prey.
