Things to know for quiz Electromagnetic spectrum: we can see 400-700 nm Wave length scale nm: energy is wave lengths, one nm is 10^-9, wavelength on the scale goes from 10^-3 to 10^15 Look at visual system picture on slide: -eye -lateral generculit nucleues (LGN) located in thalamus -the striate cortex (located in accipital lobe) => higher level visual processing, anything past V1 -retina is where we see our sensory receptors, this is where transduction happens - Contralateral goes on the other side of the brain and ipsalteral stays on the same side 4 cells (know ganglion specifically form in the optic nerve): amacrine cells, bipolar cells, horizontal cells, ganglion cells The vertebrate retina (cross-section through the retina) quiz myself => know parts/layers of the retina: Rods and cones (amounts and locations/roles): -(rods/monochramatics): -used for night or dark vision -each retina has about 120 rods -peripheral retina has about 20:1 ratio 20 rods for 1 cone -rods are most sensitive to wavelengths of 500 nm - Purkinje shift- is when shift to lower light levels, with shorter wavelengths -(cones): used for color or day vision - each retina has about 5 million cones -fovea contains only cones (about 50k) -cones sensitive to short wave lengths which is blue -medium wave length sensitive to yellow and green - long wave lengths sensitive to red * Retinal is responsible for transduction by absorption of photons—a process called isomerization enzyme cascade: This isomerization can then create an electrical signal by which many more molecules (as many as a million) are stimulated, through a process called enzyme cascade convergence: Receptors synapse (attach) onto ganglion cells • Typically there is a one-to-one relationship between cones and their ganglion cells (about 1 cone to each ganglion cell) • Convergence occurs when more than one cell converges onto another cell • Typically rods operate by convergence • 126 million receptors, and 1 million ganglion cells • Cone have one to one mapping to a ganglion cell so it usually doesn’t have enough to fire unless there is enough energy in the cone cell to make the ganglion cell fire action potential: a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Cross section of the vertebrate of eye: Parts of the brain and their functions: -Frontal cortex: cog functions -temporal lobe: hearing and language comprehension -occipital lobe: visual processing -pituitary gland: hormones, growth, fertility -parential lobe: intelligence, reasoning
