Fabrizio Musacchio<p>🧠 New preprint by Ruff, Markman, Kim &amp; Cohen (2025): <a href="https://sigmoid.social/tags/NeuralPopulation" class="mention hashtag" rel="tag">#<span>NeuralPopulation</span></a> formatting matters for function. In monkeys combining motion and reward, both middle temporal area (<a href="https://sigmoid.social/tags/MT" class="mention hashtag" rel="tag">#<span>MT</span></a>) &amp; dorsolateral prefrontal <a href="https://sigmoid.social/tags/cortex" class="mention hashtag" rel="tag">#<span>cortex</span></a> (<a href="https://sigmoid.social/tags/dlPFC" class="mention hashtag" rel="tag">#<span>dlPFC</span></a>) encode both signals. But MT formats them separately, dlPFC integrates them.
