Visual thinking, also called visual or spatial learning or picture thinking, is the phenomenon of thinking through visual processing. [1] Visual thinking has been described as seeing words as a series of pictures. [2] [3] It is common in approximately 60–65% of the general population. [1] "Real picture thinkers", those who use visual thinking ...
The Purkinje tree is an image of the retinal blood vessels in one's own eye, first described by Purkyně in 1823. It can be seen by shining the beam of a small bright light through the pupil from the periphery of a subject's vision. This results in an image of the light being focused on the periphery of the retina.

To experience the "lilac chaser" effect, the subject needs to fixate their eyes on the cross in the middle of the image, and after a while the effect will settle in. Visual coding, a process involved in visual adaptation, is the means by which the brain adapts to certain stimuli, resulting in a biased perception of those stimuli.
Ordinary people have better reading performance using high-frequency (20–60 kHz) electronic ballasts than magnetic ballasts, [10] although the effect was small except at high contrast ratio. The flicker of fluorescent lamps, even with magnetic ballasts, is so rapid that it is unlikely to present a hazard to individuals with epilepsy . [ 11 ]
These images can be a result of distortion of incoming sensory information leading to an incorrect perception of a real image called an illusion. When the visual system produces images which are not based on sensory input, they can be referred to as hallucinations. The visual phenomena may last from brief moments to several hours, but they also ...
Brain-reading or thought identification uses the responses of multiple voxels in the brain evoked by stimulus then detected by fMRI in order to decode the original stimulus. . Advances in research have made this possible by using human neuroimaging to decode a person's conscious experience based on non-invasive measurements of an individual's brain activit
Creative visualization is the cognitive process of purposefully generating visual mental imagery, with eyes open or closed, [1] [2] simulating or recreating visual perception, [3] [4] in order to maintain, inspect, and transform those images, [5] consequently modifying their associated emotions or feelings, [6] [7] [8] with intent to experience a subsequent beneficial physiological ...
