Psychedelics

We aim to unravel the neurocognitive mechanisms underlying the psychedelic experience, at both a brain and bodily level of investigation.

VIDI Project

As of September 2021 we will launch the VIDI project ‘Putting Psychedelics in Perspective’. The aim of this project is

(1) To replicate existing findings on the neurocognitive mechanisms underlying psychedelics,

(2) To study the role of the placebo-effect in relation to the psychedelic experience

(3) To compare different mystical-type experiences induced through different techniques (e.g., sensory deprivation, VR, god-helmets etc.)

Microdosing

Microdosing is an increasingly popular trend amongst psychedelic communities and refers to a practice where individuals consume sub-perceptual amounts of a psychedelic substance (e.g., LSD or psilocybin) every 2-4 days. Sub-perceptual dosage denotes quantities which reportedly do not induce any (conscious) perceptual alterations but allegedly induce creativity and improve mood. The popularity of such claims may be linked to the emergence of microdosing communities that circulate anecdotal evidence. As of now there are few scientific most of which rely on self-report sources.

We conducted a study to investigate the consequences of microdosing with regard to cognitive styles of visual processing, time perception and emotional processing to enhance our scientific understanding of the effects of microdosing. This will also allow informing the general public on previously unrecognized risks and effects of microdosing. In the Netherlands only a few psychedelic substances are allowed legally. Therefore our study is restricted to psilocybin-containing truffles that can be purchased legally through licensed smartshops

Retreat studies

We are currently collaborating with several retreats to investigate the effects of psychedelics in ceremonial settings. Read more about our retreat projects:
