Earlier studies have shown that visual function in skate is subserved solely by the rod mechanism and that the retina of this elasmobranch contains only rod photoreceptors. Nevertheless, the skate retina is capable of responding to levels of illumina

Ampullary organs of the transparent catfish, Kryptopterus bicirrhus, are present in large numbers on the head and in a regular pattern of lines on the body and fins. The organs lie in the epidermis, and have a pore that opens to the surface. Flattene

The special cutaneous receptor organs of the fresh water weakly electric fish have previously been proposed to be electroreceptors. In the gymnotid, E. virescens, two types of special cutaneous receptor organs, ampullary and tuberous, are distinguish

Electroreceptors (ampullary organs) of the transparent catfish (Kryptopterus bicirrhus) lie in the epidermis, and contain spherical receptor cells that receive purely afferent innervation from the lateral line nerve. Section of this nerve causes rapi

Both ampullary and tuberous special cutaneous receptor organs are present in the gymnotid fish Hypopomus. The ampullary receptor organs are morphologically very much like those of the related genus, Eigenmannia, in organ structure and receptor cell u

Sites of synaptic transmission between receptor cells and afferent nerves in electroreceptors of elasmobranchs are distinguished by a dense presynaptic ribbon surrounded by synaptic vesicles. Digestion by pronase or protease of thin sections of Epon

Autopsy eyes were examined from a 79-year-old female carrier of X-chromosome-linked retinitis pigmentosa. At age 78 years, she had no visual symptoms but had intraretinal bone spicule pigmentation in the nasal and inferior periphery of both eyes. Rod

The role of the Müller cell in the generation of the ERG b-wave was studied in the skate eye by examining the effects of a gliotoxic agent (alpha-aminoadipic acid; alpha-AAA) on retinal structure and function. Superfusing the eyecup for 1 h in 50 mM

Ampullary receptor organs of African mormyrids consist of a cavity beneath the epidermis. The wall of the cavity contains embedded receptor cells and two types of supporting cells. A canal extends from the cavity to an opening at the surface. The lum

Special cutaneous receptor organs of fresh-water weakly electric fish are grossly similar to other receptor organs of the acoustico-lateralis system, but differ in numerous cytological details. They are presumed to function as detectors of weak elect
