Abstract: . . . during the first 50-100 microseconds following illumination and found in LERG’s with amplifiers operating at very high sensitivity. 3. The initial transient in the ERG occurring during the first few milliseconds after illumination of the photoreceptor cells. Ectopic signal generation– The spontaneous generation of action potentials due to pathological conditions. Page 19 Glossary - 19 Edinger-Westphal nucleus– A signal processing engine identified primarily on morphological grounds based on the response to lesion in this area. It is considered a major part of the parasympathetic motor pool of the oculomotor nuclear complex. It appears to participate primarily in pupillary and accommodation functions (Glaser, pg 339). Efferent-- Directed away . . . . . . Equivalent to the term convergent when discussing relative disparity. See also uncrossed disparate. CSF-- The cerebral-spinal fluid containing the brain and acting as the electrical ground plane for the neurons of the brain Current availability curve– A term used in the vernacular to describe the static potential and current sourcing capability of the electrostenolytic process supporting a plasma in a neuron. Cyanopsin-- A conceptual name synonymous with Rhodonine(5) in the liquid crystalline form and derived from its observed broadband absorption. This anisotropic absorption exhibits a spectral absorption peak at 625 nm. Cyanolab – (obsolete) A conceptual name associated with Rhodonine(3), the short wavelength chromophore of vision . See Rhodonine. . . . . . . vision 2000 Page 1 Glossary - 1 Date: 27 January 2004 GLOSSARY supporting “Processes in Biological Vision ” © 2000 James T. Fulton, author www.4colorvision.com This Glossary is a record of the paradigm shift in the visual sciences cataloged in the accompanying text, “Processes in Biological Vision .” The definitions provided here take precedence over other definitions in the literature. For a broader glossary of many Biological and medical terms (except those introduced here), the reader might look at the Online Medical Dictionary at www.graylab.ac.uk/omd/ . • A glossary of the neurosciences appears in Review of Neurosciences, 2 nd ed. . . . . . . both the fusion and depth perception phenomenon of vision . Double layer-- 1. (Semiconductor physics) The space charge distribution surrounding and defining the location of a junction, either electrolytic or solid state, under equilibrium conditions. Page 18 18-Processes in Animal Vision 2. (Cytology) A colloquial name for the bilayer membrane forming the external wall of a biological cell. See bilayer. Drusen– 1. clinically visible (>25 microns) mounds in the inner collagenous zone of Bruch’s membrane. 2. Yellow-white deposits found under the macula. Drusen deposits are associated with the dry form of macular degeneration. They are thought to be an accumulation of waste materials Duct-- In a glandular context, the manifold created in a compound . . . --3000,4,375,3202,59157
