AbstractToday, there is an increased interest in research on lysergic acid diethylamide (LSD) because it may offer new opportunities in psychotherapy under controlled settings. The more we know about how a drug works in the brain, the more opportunities there will be to exploit it in medicine. Here, based on our previously published papers and investigations, we suggest that LSD-induced visual hallucinations/phosphenes may be due to the transient enhancement of bioluminescent photons in the early retinotopic visual system in blind as well as healthy people.

Background: Recent evidence suggests that psychedelic use predicts reduced perpetration of intimate partner violence among men involved in the criminal justice system. However, the extent to which this association generalizes to community samples has not been examined, and potential mechanisms underlying this association have not been directly explored. Aims: The present study examined the association between lifetime psychedelic use and intimate partner violence among a community sample of men and women. The study also tested the extent to which the associations were mediated by improved emotion regulation. Methods: We surveyed 1266 community members aged 16–70 (mean age=22.78, standard deviation =7.71) using an online questionnaire that queried substance use, emotional regulation, and intimate partner violence. Respondents were coded as psychedelic users if they reported one or more instance of using lysergic acid diethylamide and/or psilocybin mushrooms in their lifetime. Results/outcomes: Males reporting any experience using lysergic acid diethylamide and/or psilocybin mushrooms had decreased odds of perpetrating physical violence against their current partner (odds ratio=0.42, p<0.05). Furthermore, our analyses revealed that male psychedelic users reported better emotion regulation when compared to males with no history of psychedelic use. Better emotion regulation mediated the relationship between psychedelic use and lower perpetration of intimate partner violence. This relationship did not extend to females within our sample. Conclusions/interpretation: These findings extend prior research showing a negative relationship between psychedelic use and intimate partner violence, and highlight the potential role of emotion regulation in this association.

Real Time Information

Background: Social interactions require rapid, real-time information integration and performative application of dynamic social information, and can be especially difficult for patients with schizophrenia. Their difficulty processing social information could lie in challenges extracting the information or in updating their actions to accommodate the new information, resulting in behaviors that may appear rigid or inappropriate. Disruptions may emerge in the underlying, requisite behavioral or neural processes. Methods: Seventeen matched healthy controls and seventeen patients with schizophrenia participated in an fMRI study, which included a social interaction priming procedure wherein they met a friendly stranger who held opposite social values from their own. They answered self-judgement questions about their social values two days before the priming experiment and again during the fMRI scan. Results: Controls suppress social values when interacting with the stranger whereas patients with schizophrenia augment the opposite values, simultaneously holding two sets of social values. Compared to controls, patients display hyperactivity in dorsomedial prefrontal cortex and atypical activity in caudate, posterior cingulate and precuneus. Discussion: Patients appear to correctly extract social information but apply the information atypically. They display evidence of atypical social flexibility on both performative and neural measures, resulting in confusion between self and other.

The Many

Serendipity is one of the many factors that may contribute to drug discovery. It has played a role in the discovery of prototype psychotropic drugs that led to modern pharmacological treatment in psychiatry. It has also played a role in the discovery of several drugs that have had an impact on the development of psychiatry. "Serendipity" in drug discovery implies the finding of one thing while looking for something else. This was the case in six of the twelve serendipitous discoveries reviewed in this paper, i.e., aniline purple, penicillin, lysergic acid diethylamide, meprobamate, chlorpromazine, and imipramine. In the case of three drugs, i.e., potassium bromide, chloral hydrate, and lithium, the discovery was serendipitous because an utterly false rationale led to correct empirical results; and in case of two others, i.e., iproniazid and sildenafil, because valuable indications were found for these drugs which were not initially those sought The discovery of one of the twelve drugs, chlordiazepoxide, was sheer luck.
