Lukas Wießner

I. Wießner (full given name not available in supplied records) is a researcher active in experimental human psychopharmacology with a specific focus on lysergic acid diethylamide (LSD). Wießner is listed as an author on multiple healthy-volunteer studies and drafts that probe LSD's effects across cognitive domains — including episodic memory, verbal fluency and cognitive flexibility — and on higher-order processes such as creativity, language production and the phenomenology of mystical experiences. The body of work represented in the available records emphasises careful behavioural characterisation of acute drug effects as well as so-called afterglow and hangover phenomena.
