Neurons that tracked a remembered smell turned up all over the mouse brain in a newly released dataset of 33,028 neurons recorded from 40 mice. The 2026 data paper makes those recordings free for other scientists to study how working memory works.1 Research Highlights Memory neurons in every well-sampled region: in all 34 brain regions …
