The cerebellum of mormyrid fish is of interest for its large size and unusual histology. The mormyrid cerebellum, as in all ray-finned fishes, has three subdivisions--valvula, corpus, and caudal lobe. The structures of the mormyrid valvula and corpus have been examined previously, but the structure of the mormyrid caudal lobe has not been studied. The(More)
Primary afferent fibers from the electroreceptors of mormyrid electric fish use a latency code to signal the intensity of electrical current evoked by the fish's own electric organ discharge (EOD). The afferent fibers terminate centrally in the deep and superficial granular layers of the electrosensory lobe with morphologically mixed chemical-electrical(More)
The mormyrid electric …sh displays extremely …ne temporal resolution as measured in be-havioral studies. The …rst stage of sensory processing, the sensory a¤erents, also display very precise temporal responses to electrical stimulation. The a¤erents are connected through gap junctions to the granular cells, which in addition receive a corollary discharge(More)
Retinal fundus image plays an important role in the diagnosis of retinal related diseases. The detailed information of the retinal fundus image such as small vessels, microaneurysms, and exudates may be in low contrast, and retinal image enhancement usually gives help to analyze diseases related to retinal fundus image. Current image enhancement methods may(More)
OBJECTIVE To observe some of bio-chemical indice of rats striatum poisoned by rotenone. METHODS Apply the method of back-implantation mini-effusion pump to observe influence of different concentration rotenone on the rat striatum. Utilize Fluoro-Jade B combined Fluorescent dying to observe the change conditions of the neural cells of the poisoned rat(More)
