Today I will be teaching my undergrad course "How to build a brain from scratch" for the 2nd year running. I've put the materials online - include a document with all lecture slides and notes, which is about as long as a decent novel. Enjoy!https://humaninformationprocessing.com/teaching/

There is no universal consensus on how to conduct and report Bayesian analyses.
@BalazsAczel & colleagues present their views on the debate in a Comment, providing a thinking guideline for scientists wishing to employ Bayesian inference in their researchhttps://buff.ly/3aMi8a6Hvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

All current successful quantum models for human cognition lack connections to neuroscience. Li et al. show that quantum reinforcement learning can explain value-based decision making at both the behavioural and neural levels.https://buff.ly/2TFVCtx

A Perspective in
@NatureHumBehav proposes a framework of information-seeking, whereby individuals decide to seek or avoid information based on combined estimates of the potential impact of information on their action, affect and cognition. https://go.nature.com/2tnYMaA pic.twitter.com/p61brpBN0J

Cues that predict reward activate dopamine neurons but the function of this response remained unclear. This study demonstrates that inhibiting dopamine cue responses impairs second-order conditioning as predicted from TD learning theory. Elegant study!http://feeds.nature.com/~r/neuro/rss/current/~3/ECPr9FLKcvw/s41593-019-0574-1 …

Very happy to have this out! Dopamine transients produce learning about antecedent cues, without making those cues valuable. https://www.nature.com/articles/s41467-019-13953-1 … Thread below summarizes our key points

Very excited about our new paper: "Ventromedial prefrontal cortex compression during learning". vmPFC coding akin to goal-directed dimensionality reduction and tracks attention weights from learning models.
