Incredible week at #EBPS2025. Great location, great science, great food, and great friends. Can’t wait to do it again. Looking forward to our new leadership from @gavanm.bsky.social. Keep your eyes peeled for our new communications initiatives 😉
Fascinating study, you can also read my Research Highlight on this paper and connectome harmonics here pubmed.ncbi.nlm.nih.gov/40940590/
This recent study finds that DMT reshapes the 🧠’s connectome harmonic repertoire, mirroring effects of psilocybin, LSD & ketamine, with entropy and energy spectrum changes closely tracking the intensity of participants’ subjective experiences 🍄💊

Arutiunian and colleagues found that youth with Autism Spectrum Disorder have altered EEG alpha-band activity(particularly in younger males), which is linked to poorer language skills, more autistic traits, and higher genetic burden from copy number variations.
Number of alpha peaks in the electroencephalogram is associated with clinical phenotype and copy number variation in youths with autism
EEG alpha-band neural activity has been previously reported to be altered in Autism Spectrum Disorder (ASD), but no studies have been done addressing different parameters of alpha-band activity, their...

It was a great day @westernu.ca, and such an honor to be selected by students for the Treva Glazebrook Lecture. Thank you, Kendra Loedige, for being a wonderful host. Great to see you and catch up, @drjkhokhar.bsky.social - thanks for teaching me about academia in Canada. 🤩🇨🇦
So great to have @flagel-lab.bsky.social give the 2025 Treva Glazebrook Lecture @westernu.ca today! A master-class in the neurobiology of inhibitory control! The lecture is voted on and hosted by neuroscience trainees and they picked a good one! @westernuwin.bsky.social

Congrats to @pact-lab.bsky.social PhD student @anadeutsch.bsky.social on her 1st first-author paper from the lab! 🎉

She explored how MDMA & methamphetamine impact cortisol, endocannabinoids, & BDNF levels in healthy humans and how this relates to the subjective drug experience 💊👇
The effect of methamphetamine and 3,4-methylenedioxymethamphetamine on peripheral endocannabinoid concentrations: a study in healthy adults - Psychopharmacology
Rationale Stimulant drugs such as methamphetamine (MA) and 3,4-methylenedioxymethamphetamine (MDMA) can impact neurobiological systems implicated in stress, reward processing, and drug use. Although recent preclinical evidence implicates the endocannabinoid (eCB) system in these processes, little is known about the acute effects of stimulants on eCB levels in humans. Objectives The aim of the present study was to investigate the effects of acute administration of the prototypical psychostimulant MA and the psychostimulant-empathogen MDMA on circulating eCB levels in healthy adults. Methods Using a within-subject, double-blind design, this study assessed the acute effects of MA (20 mg), MDMA (100 mg), and placebo on plasma eCB levels in healthy human participants (N = 22) during three separate sessions. Blood samples assessing concentrations of the eCBs anandamide (AEA) and 2-Arachidonoylglycerol (2-AG) were collected between 150- and 180-minutes post-drug administration, and subjective measures of drug effects were collected at regular intervals. Results MA, but not MDMA, was associated with significantly lower 2-AG plasma concentrations compared to placebo. Neither drug impacted AEA concentrations. However, during the placebo condition, higher AEA concentrations were correlated with disliking the ‘drug effects’, suggesting a possible relationship between AEA levels and negative expectations of subjective drug effects. Conclusions These findings provide novel insights into how stimulant drugs act on the eCB system and may help to develop treatments for SUDs.

Matt making October easy for us who watch a horror film a day through the month 😏
Its Halloween season 🎃 and since the world is hellfire, what better way to distract ourselves then with horror movies!

The 2020s have already proven to be one of the best eras for horror ever. To fill your October with some viewing ideas, this is my list of the top 30 horror movies of the 2020s.
