New paper by Bruno Moses, Enzo Tagliazucchi, & me in which we critique the Entropic Brain Hypothesis & neural entropy metrics regarding what they can tell us about psychedelic fx. Lots of technical and theoretical points, but I'd like to highlight a few. 1/10 www.sciencedirect.com/science/arti...

A critical review of brain entropy as a biomarker of the psychedelic state

Serotonergic psychedelics induce profound alterations in consciousness, giving rise to an altered state commonly referred to as the psychedelic state.…

This paper has been a long time coming. Instead of reanalyzing the same old resting-state fMRI datasets, we combined nearly all datasets around the world. Note that we didn't exactly find indisputable evidence for "default mode network disintegration." www.nature.com/articles/s41...

An international mega-analysis of psychedelic drug effects on brain circuit function - Nature Medicine

Analysis of neuroimaging datasets across five major psychedelics revealed a shared brain signature and provides a comprehensive insight into how these drugs reorganize brain architecture.

New lab paper: "Emotional learning selectively distorts the temporal organization of memory: A quantitative synthesis." Across 17 different studies, fear conditioning consistently distorted temporal source memory for information encoded before and after. www.sciencedirect.com/science/arti...

Emotional learning selectively distorts the temporal organization of memory: A quantitative synthesis

Episodic memory allows us to remember when an event occurred by situating it within a coherent temporal context. Pavlovian fear conditioning, a widely…

What happens if you inhibit the amygdala during the formation of emotional episodic memories? Simple answer, right? We thought so too but ended up finding memory enhancements after inhibiting the amygdala via transcranial focused ultrasound (tFUS). 1/2 www.biorxiv.org/content/10.1...

Enhanced Episodic Memory Following Putative Inhibition of the Amygdala via Transcranial Low-Intensity Focused Ultrasound

The amygdala is considered crucial to the formation of emotional episodic memories, but causal evidence in humans is limited due to challenges in non-invasive neuromodulation of deep brain structures....

New paper!!! Pooled data (17 conditioning+memory exp) to figure out (a) robustness of emotional temporal biases (attribute items to threat context even if encoded before or afterwards) and (b) how this predicts emotional memory enhancement. www.sciencedirect.com/science/arti...

I haven't posted on here much, but this new paper from the lab seems like as good reason as any: How the nature of weak learning and retention interval affects behavioral tagging of episodic memory. psycnet.apa.org/record/2026-...

So pleased to share the (maybe?) final output from my PhD thesis (2yrs later), a labor of love (specifically, love of learning theory) We outline a view of 'Pavlovian safety learning' as an interesting psychological construct in its own right, based on insights from learning theory rdcu.be/dRCSg

Excited to share a new paper w Dani Bassett on "Causation in neuroscience: keeping mechanism meaningful" in Nature Reviews Neuroscience We explore different meanings of mechanism in the field, the challenges this presents & how to move forward. 🧠 www.nature.com/articles/s41...

Causation in neuroscience: keeping mechanism meaningful - Nature Reviews Neuroscience

‘Mechanism’ is a frequently used causal concept in neuroscience but can have different meanings that are often not specified. In this Review, Ross and Bassett explore these different meanings and ...
