Visual memory describes the relationship between perceptual processing and the encoding, storage and retrieval of the resulting neural representations. Visual memory occurs over a broad time range spanning from eye movements to years in order to visually navigate to a previously visited location. Visual memory is a form of memory which preserves some characteristics of our senses pertaining to visual experience. We are able to place in memory visual information which resembles objects, places, animals or people in a mental image. The experience of visual memory is also referred to as the mind's eye through which we can retrieve from our memory a mental image of original objects, places, animals or people. Visual memory is one of several cognitive systems, which are all interconnected parts that combine to form the human memory. .

In humans, areas specialized for visual object recognition in the ventral stream have a more inferior location in the temporal cortex, whereas areas specialized for the visual-spatial location of objects in the dorsal stream have a more superior location in the parietal cortex. However, this two streams hypothesis, although useful, is a simplification of the visual system because the two streams maintain intercommunications along their entire rostral course.

Derren Victor Brown (born 27 February 1971) is an English illusionist, mentalist, painter, writer and sceptic. He is known for his appearances in television specials, stage productions, photographic memory, and British television series such as Trick of the Mind and Trick or Treat. Since the first broadcast of his show Derren Brown: Mind Control in 2000, Brown has become increasingly well known for his "mind-reading" act. He has written books for magicians as well as the general public. His caricature artwork has received gallery exhibition and is available in a single volume documenting his portrait collection.

Though his performances of mind-reading and other feats of mentalism may appear to be the result of psychic or paranormal practices, he claims no such abilities and frequently denounces those who do. Brown states at the beginning of his Trick of the Mind programmes that he achieves his results using a combination of "magic, suggestion, psychology, misdirection and showmanship". Using his knowledge and skill, he appears to be able to predict and influence people's thoughts with subtle suggestion, manipulate the decision-making process and read the subtle physical and psychological signs or body language that indicate what a person is thinking.
