#CRSy23 #BrainBodyWorld23 aims to foster the discussion of how internal states, such as hunger, thirst, and emotion, are generated and regulated by the brain, and how they interact with the body and the external world to drive behaviour. 

A study published today, April 13th, in the journal Nature Neuroscience provides a surprising answer to this question by showing that, rather than committing to a single strategy, the brain can compute multiple alternative decision strategies simultaneously.

The study, led by Fanny Cazettes and senior authors Zachary Mainen and Alfonso Renart, at the Champalimaud Foundation in Lisbon, Portugal, performed a specially-designed experiment which used a kind of “virtual reality” setup for mice, in which the animals were tasked with searching for water in a virtual world.
