Representational drift - the change in cells' responses to the same stimulus over time - may be a feature rather than a bug.
Thank you to @dianakwon.bsky.social for giving me a chance to talk about this fascinating topic. 🤯 The brain never ceases to amaze!

My latest feature for @nature.com is about "representational drift," a concept that's turned some long-standing ideas of how the brain works on its head.

A hackathon reveals that disagreement in neuroscience runs deeper than most researchers suspect—even in electrophysiology, a field that prides itself on hard data, write @mattiachini.bsky.social and Gaelle Chapuis. #neuroskyence

American science right now is basically 10,000 of these stories, all with their own heartbreaking specificity
Lost careers, lost progress, lost discoveries
I feel so sad every day for all we’ve lost and continue to lose 💔
