My first paper with @naoshigeuchida.bsky.social is finally out in @natcomms.nature.com ! rdcu.be/eACGf
TL;DR: asymmetric learning rates can be induced by shifts in tonic dopamine giving rise to pessimistic/optimistic biases in agents or animals undergoing reinforcement learning .

Tonic dopamine and biases in value learning linked through a biologically inspired reinforcement learning model
Nature Communications - Accurate future predictions are essential for guiding behavior, and disruptions in this process are associated with psychiatric disorders. Here the authors show that changes...

Thank you for the nice article, @thetransmitter.bsky.social 🐦☺️
For black-capped chickadees, looking out at a location activates the same place cells as actually being there, a study from Columbia University shows.

Gazing from afar activates place cells in chickadees
The results help explain how the hippocampus can recall information about a place without an animal physically revisiting it.

My latest Aronov lab paper is now published @Nature!
When a chickadee looks at a distant location, the same place cells activate as if it were actually there 👁️
The hippocampus encodes where the bird is looking, AND what it expects to see next -- enabling spatial reasoning from afar
