🎇 Excited to finally share JL Romero Sosa’s publication! Results are from single-cell imaging in different subregions of rat frontal cortex during ✨de novo learning. Spoiler: everything is not everywhere all at once

Neural coding of choice and outcome are modulated by uncertainty in orbitofrontal but not secondary motor cortex - Nature Communications
Neural mechanisms underlying flexible learning and decision-making are not fully understood. Using single-cell calcium imaging, authors here found that neurons in orbitofrontal and secondary motor cortex exhibit complementary roles in reward learning, with neurons in the former exerting a sustained role in conditions of uncertainty.

Why don’t some of us learn from punishment?
Individuals differ drastically in whether they will cease actions with negative consequences. Using a specially-designed task, we explore the psychological roots for these differences, its stability a...

Knowing better, doing worse: the science behind self-sabotaging behaviour
UNSW researchers uncover why some people persist in harmful behaviours – even when they’ve been shown where they’re going wrong.

We created a photometry python package for unbiased standardised post-hoc analysis using bootstrapping confidence intervals No more AUC or time bins analysis! Ever Follow our simple step by step instructions.

We have outlined issues with typical pre-processing steps for fibre photometry analysis.
doi.org/10.1117/1.NP...
Main: standard linear fitting of isosbestic to experimental signals = BAD! IRLS is conceptually+demonstrably better. Lots discussed in paper. Code posted at

Have been away from social media, which has been nice. But figure I really should post some updates about what the lab has been up to. Posts incoming.
