Lets distinguish belief from knowledge. And lets say clearly which is which. We need to take neuroscience seriously if we are to make progress.

👁️🧠 New preprint: We demonstrate the first data-driven neural control framework for a visual cortical implant in a blind human!
TL;DR Deep learning lets us synthesize efficient stimulation patterns that reliably evoke percepts, outperforming conventional calibration.

Can your AI beat a mouse?
Mice still outperform our best computing machines in some ways. One way is robust visual processing.
10 years ago I decided to work on HARD behavior driven by COMPLEX visual processing. And that risk is paying off now. #neuroAI 1/n

Why are CNNs so good at predicting neural responses in the primate visual system? Is it their design (architecture) or learning (training)? And does this change along the visual hierarchy?
