Abstract
Rationale: Since the earliest LSD research, psychedelics have been claimed to enhance autobiographical memory. Revisiting and processing autobiographical memories has further been suggested to be a major component of the therapeutic action of psychedelics. However, modern psychedelic research has largely neglected autobiographical elements of psychedelic experiences, and many vital questions remain unanswered.
Objectives: We present and discuss six open questions related to psychedelics and autobiographical memory: (1) Do psychedelics enhance autobiographical recall? (2) Is recall and processing of significant autobiographical (e.g., traumatic) memories a common part of psychedelic experiences? (3) Do psychedelics promote the development of false or inaccurate memories? (4) How do autobiographical memories change if they are recalled and reconsolidated under the effects of psychedelics? (5) What are memories of psychedelic experiences like? (6) Are autobiographical experiences under psychedelics of particular importance for their therapeutic effects?
Results: We present the background and current limited state of evidence for each question and provide suggestions on how future studies could best address them.
Conclusions: Besides advancing basic research, answering these pressing questions is highly relevant for the possible therapeutic use of psychedelics, both in terms of developing and optimizing new interventions and for avoiding iatrogenic harms. Ideally, future psychedelic-assisted interventions could harness the possible synergies between the effects of psychedelics and existing memory-based therapies.
期刊介绍：
Official Journal of the European Behavioural Pharmacology Society (EBPS)
Psychopharmacology is an international journal that covers the broad topic of elucidating mechanisms by which drugs affect behavior. The scope of the journal encompasses the following fields:
Human Psychopharmacology: Experimental
This section includes manuscripts describing the effects of drugs on mood, behavior, cognition and physiology in humans. The journal encourages submissions that involve brain imaging, genetics, neuroendocrinology, and developmental topics. Usually manuscripts in this section describe studies conducted under controlled conditions, but occasionally descriptive or observational studies are also considered.
Human Psychopharmacology: Clinical and Translational
This section comprises studies addressing the broad intersection of drugs and psychiatric illness. This includes not only clinical trials and studies of drug usage and metabolism, drug surveillance, and pharmacoepidemiology, but also work utilizing the entire range of clinically relevant methodologies, including neuroimaging, pharmacogenetics, cognitive science, biomarkers, and others. Work directed toward the translation of preclinical to clinical knowledge is especially encouraged. The key feature of submissions to this section is that they involve a focus on clinical aspects.
Preclinical psychopharmacology: Behavioral and Neural
This section considers reports on the effects of compounds with defined chemical structures on any aspect of behavior, in particular when correlated with neurochemical effects, in species other than humans. Manuscripts containing neuroscientific techniques in combination with behavior are welcome. We encourage reports of studies that provide insight into the mechanisms of drug action, at the behavioral and molecular levels.
Preclinical Psychopharmacology: Translational
This section considers manuscripts that enhance the confidence in a central mechanism that could be of therapeutic value for psychiatric or neurological patients, using disease-relevant preclinical models and tests, or that report on preclinical manipulations and challenges that have the potential to be translated to the clinic. Studies aiming at the refinement of preclinical models based upon clinical findings (back-translation) will also be considered. The journal particularly encourages submissions that integrate measures of target tissue exposure, activity on the molecular target and/or modulation of the targeted biochemical pathways.
Preclinical Psychopharmacology: Molecular, Genetic and Epigenetic
This section focuses on the molecular and cellular actions of neuropharmacological agents / drugs, and the identification / validation of drug targets affecting the CNS in health and disease. We particularly encourage studies that provide insight into the mechanisms of drug action at the molecular level. Manuscripts containing evidence for genetic or epigenetic effects on neurochemistry or behavior are welcome.
