... ON neurons OFF neurons Intrinsic properties Electric image Early sensory processing Mormyriformes in Africa and Gymnotiformes in America have convergently evolved an active electric sense, which appears to be their most important sensory modality ( Lissmann, 1958 ; Fessard, 1974 ; Bullock...

... of signal processing in various sensory modalities and diverse taxa. First, we refer to the one-spike neuron intrinsic properties, their foundation on a low-threshold K + conductance, and the potential roles of this phenotype in different circuits within a comparative framework. Second, we present a brief...

... ( Bennett,1971 ; Caputi et al.,2005 ). In most gymnotid pulse species, the intrinsic properties, the innervation and the activation time of the electrocytes are dependent on electrocyte location ( Caputi et al., 1989 ; Caputi et al., 1994 ). Thus,the EODs of pulse-emitting species can be likened...
