In this perspective we discuss task-driven & data-driven models as well as how they pave the way towards causal neuroscience. We focus on the vision, sensorimotor control and language processing.

Paper of the week: Our collaborative study with Yihong Yang's imaging lab, published in @npp_journal (first author: Zilu Ma), on the role of the dorsal striatum in incubation of opioid craving after voluntary abstinence in rats pubmed.ncbi.nlm.nih.gov/39300270/

Some experimental findings are inconsistent with the dominant model of reward prediction error, highlighting the need for alternative testable and falsifiable models for dopamine function. @vijay_mkn explains: thetransmitter.org/dopamine/dopam…

Our paper on how neurons represent past and future events to form a continuous timeline--just like how we intuitively experience time--is now published! pnas.org/doi/10.1073/pn…

How can memories persist in the brain when their properties and supporting biological substrates change over time and experiences? Our latest work newly published in @ScienceMagazine proposes that a balance between memory dynamics and persistence is achieved through the…

Almost three years in the making, the preprint is out! We take another stab at the question: How do humans learn from reinforcement? (Spoiler alert: the answer is _not_ Reinforcement Learning). Huge thanks to the dream team: @summerfieldlab @nathanieldaw @kevinjmiller10

New #RLC2024 paper Three Dogmas of Reinforcement Learning joint w/ @mark_ho_ and @aharutyu! arxiv.org/pdf/2407.10583 We reflect on where our scientific paradigm needs adjustment, and suggest three departures from previous conventions. Curious to hear what folks think! 🧵

Gallistel's Rate Estimation Theory is an important but still under-appreciated set of ideas about the nature of associative learning. I've developed them in a new direction: osf.io/preprints/psya… The TL;DR is that you can do Bayesian rate estimation with error-driven learning.
