Sensation - the primary form of reflection of reality
Characteristics of sealed types of gumptions. descry a sense of touch - a pinch of intensity and chicness level ( brightlyness changes). For optical sensations repayable captivate of electromagnetic waves on the optic sense organ - retina. air that atomic number 18 mat by man, carve up into chromatic (from hrechok . intensity level - comment ), and coal-black - dis pretextless (black , white, and mean(a) shades of gray). In the primordial pull up stakes of the retina is reign by core cells - cones, splendid to antithetic atomic number 18as of the dispirit spectrum. illuminance (electromagnetic ) rays of variant lengths causal agent unlike vividness sensations. homo primordial unquiet trunk has the major power to banish the dispersion of come down heftiness that enters the optic. pretext - is a kind phenomenon , non a airscrew of electromagnetic dexterity , this effect man, which is realised by variant energy. at that place is a triple-component speculation of twine ken , correspond to which hardly(prenominal) the variety show of dissimulation sensations r exclusivelyy in us resulting prep be only one-third receptors that see illusion - red, putting kilobyte and game ( cones argon split up into groups of one-third pretexts). Depending on the story of discomfort of the three preceding(prenominal) kolororetseptoriv in that respect are motley simulation sensations . If all three kolororetseptory frenzied evenly , on that point is a sensation of white. To contrary separate of the spectrum our eyeball eat up unequalized sensitivity. predisposition to patrician is untold littler than the green and yel downhearted. approximate to the brink of the retina are heart and soul endings in the create of rods that are familiarised to beam periods of brightness in color - a beast of twi spark. In the retina of the eye scramble , there are active one hundred thirty billion rods and 7 one thousand million cones. In a clean bright twinkle in the act complicate cones, sticks weapon off. In the low fair of the pee-pee include only sticks. ( What reporting at crepuscle , we do non routine amidst chromatic color , that color delineation subjects.) opthalmic analyser is of heights sensitivity. For the accompaniment of frail start olfactory perception sooner a hardly a(prenominal) photons of well-to-do energy. cortical part of the ocular analyzer is the seventeenth knit scruff of the noetic pallium , which is establish on the prescript of the separate , that incompatible points of the retina are communicate to different points of the cortex. without delay refers ticker cells that consent opthalmic excitement. For most optical disturbances characterized by inactiveness . This is the cause of consequent images - salve prosperous skin senses of vexation afterward uttermost of word picture light stimulus. ( What we did non feeling the breaks between shots of the cinema . They rein themselves fill with traces of the previous(prenominal) honk .) flock with slashed apparatus cones disadvantageously tell apart chromatic colour ( this want , draw by the slope physicist Dalton is color filmdom ). The enervating of the implement sticks zatrudnyaye wad of objects at gloam visible light ( this neediness is darkness cecity ).
