Train your model on a task, or fit it to biological data? And once it's optimized, what does it tell us about the brain? 🧠 In our #BernsteinConference satellite workshop, we'll discuss these questions through the lenses of different optimization methods. Check it out in Room 3.104! 🤓😉

At #BernsteinConference heated debate on WM mechanisms. I love that this is still far to be settled! trained RNNs from A.Compte aligns with fruitfly direction WM data from K.Nagel: it is persistent. Large scale recording in macaque V1 in T.Moore Lab: it is not. #neuroskyence what's your take?

The neuroscience tale of how purple, really magenta, is a synthetic color not found on the spectrum. We don't perceive the environment, but become aware of the brain's processing of color. I conclude, Kant was right, there is a priori knowledge. But he never realized it was neuronal. #neuroskyence
