I just landed in Boston…giving my commencement speech at MIT tomorrow and I had the thought, “I wonder if I need a dress shirt for this” and, yall, I do.

Attractors in ANNs mog attractors in brains

Our paper in @natcomms.nature.com, we show how cognitive maps in the hippocampal system could solve the general problem of representing and relating multiple alternative action plans.  doi.org/10.1038/s414... With @doellerlab.bsky.social, Patrick Haggard, @vigano.bsky.social, Daniel Reznik

Our new paper is out in Science. What is the synaptic plasticity rule in the brain, we asked. It turns out there are multiple, even within individual neurons. Congrats Jake! www.science.org/doi/10.1126/...

Distinct synaptic plasticity rules operate across dendritic compartments in vivo during learning

Synaptic plasticity underlies learning by modifying specific synaptic inputs to reshape neural activity and behavior. However, the rules governing which synapses will undergo different forms of plasti...

A prospective code for value in the serotonin system - Nature

Merging ideas from reinforcement learning theory with recent insights into the filtering properties of the dorsal raphe nucleus, a unifying perspective is found explaining why serotonin neurons are ac...

How do we associate the flavors we experience during a meal 🍽️😋 with postingestive effects like food poisoning 🤢🤮 that arise much later? Our answer in @nature.com this week: Illness signals from the gut reactivate and strengthen flavor representations in the amygdala. 📄: nature.com/articles/s41...

A neural mechanism for learning from delayed postingestive feedback - Nature

Illness signals from the gut reactivate and strengthen flavour representations in the amygdala to support learning from delayed postingestive feedback.
