Stimulus discrimination in the diencephalon of Eigenmannia: the emergence and sharpening of a sensory filter

Neuronal reliability and sensitivity to behaviorally relevant stimulus patterns were investigated in a higher-order nucleus of the diencephalon believed to participate in the jamming avoidance response (JAR) of the weakly electric fish, Eigenmannia . Response properties of diencephalic neurons withi...

Description
Summary:Neuronal reliability and sensitivity to behaviorally relevant stimulus patterns were investigated in a higher-order nucleus of the diencephalon believed to participate in the jamming avoidance response (JAR) of the weakly electric fish, Eigenmannia . Response properties of diencephalic neurons within the nucleus electrosensorius were compared with those of lower-level "sign-selective" cells found in the torus semicircularis and the optic tectum as well as with properties of the intact behavior.
