Results（1） The bio-electrical field of prey fish presented as direct current electric field of dipole type with negative potential on head and positive potential on tail and modulated into alternating electric field by respiration rhythm;（2） During the stimulation,DON units increased their firing rate and phase coupled the stimulation wave and showed the selectivity of dipolar *** These behavioral and electrophysiological results are first solid evidence to point out that the electrosense of Sturgeon does being used in predating（feeding） behavior.

Response properties of the electrosensory neurons in hindbrain of the white sturgeon,Acipenser transmontanus

Objective The passive electrosense is a primitive sensory modality in the Chondrostei, which include sturgeon and paddlefish. Using electroreceptors, these fish detect the weak electric fields from other animals or geoelectric sources, and use this information for prey detection or other behaviors. The primary afferent fibers innervating the electroreceptors project to a single hindbrain target called the dorsal octavolateral nucleus （DON）, where the electrosensory information is first processed. Here, we investigated the electrophysiological properties of DON neurons. Methods Extracellular recording was used to investigate the response properties of DON neurons to dipole electric fields with different amplitudes and frequencies in the white sturgeon, Acipenser transmontanus. Results The DON neurons showed regular spontaneous activity and could be classified into two types： neurons with a low spontaneous rate （〈10 Hz） and those with a high spon- taneous rate （〉10 Hz）. In response to sinusoidal electric field stimuli, DON neurons showed sinusoidally-modulated and phase-locked firing. In addition, neurons showed opposite phase responses corresponding to the different directions of the dipole. Conclusion The response properties of DON neurons match the electrosensory biological function in sturgeon, as they match the characteristics of the electric fields of its prey.
