(1/7) 🚨 New preprint! 🚨
@SabineMuzellec and I, go beyond one-way ANN–brain mapping to ask:
👉 Can brain activity predict ANN units?
We call this Reverse Predictivity — it reveals hidden misalignments between high-performing ANNs and the primate brain. shorturl.at/kylPl
(2/7) The Problem
For years, ANN–brain comparisons relied on forward predictivity:
"How well do model features predict neural responses?"
✅ Good for identifying brain-like models.
❌ But it ignores whether ANN representations themselves are recoverable from the brain.
Result: Two models can look equally “brain-like” while being internally very different.
