Face in a cloud by Neil Usher - This image serves as an example of pattern recognition enhancement.

Pattern recognition enhancement can be described as an increase in a person's ability to recognise patterns (usually faces) within vague stimuli. Psychedelics enhance the availability of information managed in the brain through inhibiting the lower brain structures' gating systems.[1][2] General effects of psychedelics involve the temporary disruption of the normal neural hierarchy, replacing the normally predominant top-down control of information transfer in the brain with an increasingly bottom-up dynamic characterized by an increased influence of posterior regions over frontal areas of the brain. This decoupling of the frontal areas with the medial lobes resulted in a disorganization of the high-level networks responsible for large-scale brain network integrity, resulting in increased flexibility of networks and a more open communication among them. [3][4]

This innate ability which human beings possess in everyday life is referred to by the scientific literature as pareidolia and is a well documented phenomenon.[5][6][7] Common examples of this include spotting faces in everyday objects, such as the front of a car, or seeing different objects in clouds.

During this effect, pareidolia can become significantly more pronounced than it would usually be during everyday sober living. For example, scenery may look remarkably like detailed images, everyday objects may look like faces, and clouds may appear as fantastical objects, all without any visual alterations actually taking place. Once an image has been perceived within an object or landscape, the mind may further exaggerate this recognition through the hallucinatory effect known as transformations, which goes beyond pareidolia and becomes a standard visual hallucination.

Pattern recognition enhancement is often accompanied by other coinciding effects such as acuity enhancement and colour enhancement.[8][9] It is most commonly induced under the influence of mild dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline.
