![]() ![]() It is important to note that while environmental gating may be lowered, psychedelics' suggestibility intensifications and restructuring of internalized hierarchy of narratives within conscious experience plays a role in projecting personal biases outwards in the form of hallucinations. This process is likely also involved in the various visual, tactile, and auditory enhancements which commonly occur when under the influence of a psychedelic experience. The interruption of psychedelics to these neural pathways that inhibit the sensory gating systems may, therefore, result in an enhanced availability of sensory information which is usually filtered out by these systems. The CSTC model of the brain posits that the thalamus plays a key role in controlling or gating external sensory information to the conscious faculties and is thereby fundamentally involved in the regulation of a person's awareness and attention. It is thought that a fundamental feature of information-processing dysfunction in both hallucinogen-induced states and schizophrenia-spectrum disorders is the inability of these people to screen out, inhibit, filter, or gate irrelevant stimuli and to attend selectively to more important features of the environment. However, it can also occur to a lesser extent under the influence of certain stimulants and dissociatives such as MDMA or 3-MeO-PCP. It is most commonly induced under the influence of mild dosages of psychedelic compounds, such as LSD, psilocybin, and mescaline. Visual acuity enhancement is often accompanied by other coinciding effects such as color enhancement and pattern recognition enhancement. For example, the complexity and perceived beauty of the visual input often become apparent when looking at sceneries, nature, and everyday textures. While under the influence of this effect, it is common for people to suddenly notice patterns and details in the environment they may have never previously noticed or appreciated. This is in contrast to the default sober state where a person is only able to perceive the small area of central vision in detail. At its highest level, a person may experience the ability to observe and comprehend their entire visual field simultaneously, including their peripheral vision. The experience of this acuity enhancement can be likened to bringing a camera or projector lens that was slightly blurry into focus. This results in the visual details of the external environment becoming sharpened to the point where the edges of objects become perceived as extremely focused, clear, and defined. Visual acuity enhancement is defined as a heightening of the clearness and clarity of vision. There is also a subtle amount of visual drifting within this replication. ![]() It demonstrates the general differences between normal vision and acuity enhancement by shifting between the two states. Visual acuity enhancement by StingrayZ - This animation serves as a replication of visual acuity enhancement, which is a common psychedelic effect. ![]()
