Detailed explanation-1: -afterimage, visual illusion in which retinal impressions persist after the removal of a stimulus, believed to be caused by the continued activation of the visual system.
Detailed explanation-2: -An afterimage is an image that continues to appear in the eyes after a period of exposure to the original image. These can be either negative or positive afterimages. In most cases, this is an eye-related phenomenon, although there are some cases in which it is related to an issue called palinopsia.
Detailed explanation-3: -The stimulus for vision is light, which travels in waves. The amplitude (wave height) is associated with the sensory experience of brightness; the wavelength determines the hue (color) of the light; and the wave purity (whether there is more than one type of wave) produces the psychological experience of saturation.
Detailed explanation-4: -According to the AAO, illusory palinopsia is associated with visual distortions caused by environmental (external) factors, such as: changes in neurotransmitter receptors associated with migraine. hallucinogen persisting perception disorder (HPPD) trauma to the head.
Detailed explanation-5: -So, in a broad sense, sensory memory exists and may differ for different stimuli in every stage of sensory processing. For example, visual sensory memory exists in the receptors and bipolar cells of the retina as an afterimage.
