Fear-related psychiatric disorders such as phobias and anxiety are insufficiently treated by current therapies. Psychedelics targeting 5-HT₂A receptors show promise in modulating fear circuits, but their specific neurobiological substrates remain unclear. This study investigates the effects of 4-acetoxy-N,N-dimethyltryptamine (4-AcO-DMT), a psychedelic compound, on innate fear responses and...

Psilocin, a naturally occurring hallucinogenic component of magic mushrooms, exerts notable psychoactive effects in both humans and rodents. However, the underlying mechanisms remain not fully understood. Blood-oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) is a valuable tool in many preclinical and clinical trials for investigating changes of brain activity and...

The phenylalkylamine hallucinogen (-)-2,5-dimethoxy-4-methylamphetamine (DOM) exhibits an inverted U-shaped dose-response curve for both head twitch response (HTR) and locomotor activity in mice. Accumulated studies suggest that HTR and locomotor hyperactivity induced by DOM are mainly caused by the activation of serotonin 5-hydroxytryptamine 2 A receptor (5-HT2A receptor). However, the...

Psychedelics alter consciousness and may have potential for drug development. As psychedelics are likely therapeutically active, it is important to study their effects and mechanisms using preclinical models. Here, we examined the effects of phenylalkylamine and indoleamine psychedelics on locomotor activity and exploratory behaviour using the mouse Behavioural Pattern Monitor (BPM). DOM,...
