Why scientists are intentionally triggering hallucinations in the lab
In short: While we often view hallucinations as symptoms of disorder, researchers are finding ways to induce them on demand. By bringing these surreal experiences into a controlled environment, scientists hope to unlock the fundamental mechanisms of human consciousness and improve treatments for mental health.
Hallucinations are traditionally defined as involuntary false perceptions that occur without appropriate external sensory stimulation. While they can be distressing symptoms of pathology, they can also occur without disease, through the use of psychedelics, or as part of spiritual practices. Because hallucinations are incredibly diverse—ranging from simple visual flickers to complex, multi-sensory experiences—studying them in a clinical setting is often hindered by methodological obstacles and the difficulty of quantitative measurement. These experiences can be highly heterogeneous, appearing in a single sensory modality or across multiple senses at once. The content of these perceptions can range from the banal to the bizarre, and the individual may or may not realize the experience is unreal.
To overcome this, researchers are developing ways to induce hallucinations experimentally. Techniques such as using flickering light or classical conditioning allow scientists to bring hallucinations within the reach of objective neural and behavioral measurements. This approach treats hallucinations not as a single category of disorder, but as a continuous spectrum. On this spectrum, the suitability of a model is determined by how much external sensory information constrains the conscious experience. This method seeks to bridge the gap between the historically separate disciplines of clinical research, cognitive neuroscience, and psychophysics.
Understanding these induced states can reveal how the brain processes sensory information and how consciousness itself is structured. This research has broader implications for mental health, as strategies used to group pathological hallucinations by their neural activity and phenomenology can help guide the development of new treatments. By studying the 'dark side' of recurrent hallucinations alongside controlled, induced phenomena, science aims to bridge the gap between psychophysics, cognitive neuroscience, and clinical research. Ultimately, the goal is to use these models to alleviate the suffering caused by recurrent pathological hallucinations and to better understand the mechanisms of sensory processing.
