Groundbreaking new Stanford brain study showing that human brains have essentially two main cellular lineages that work cooperatively rather than being a single organ or three ancestral ones layered upon each other.
Even more fascinating is that the bifurcation of neural specialization can be traced to species documented as existing more than 500 million years ago. https://med.stanford.edu/news/all-news/2026/09/two-separate-brains.html

I should note further that the division is not left-versus-right but rather hind versus middle-and-front. The published paper from Nature Neuroscience is unfortunately gated (this should be disallowed for all publicly funded research imo), but you can read the preprint of it which was published last year: https://www.biorxiv.org/content/10.1101/2025.07.02.662771v2.full.pdf I'm finding the paper remarkably in conversation with my own philosophy of mind/cognitive science work, an intro to which here: https://flux.community/matthew-sheffield/2026/01/its-like-this-why-perceptions-are-our-realities/
