Cell assemblies are drawing increasing attention in neuroscience, but one could argue that they are just an epiphenomenon. Is the activity of cell assemblies relevant for the brain?
The short answer is yes. The long answer is in our paper, now online at PLOS Biology. 🧵👇 1/10

Adaptive communication between cell assemblies and “reader” neurons shapes flexible brain dynamics
Cell assemblies have been proposed as key units of brain activity, underlying diverse functions, but their basic features are not well understood. This study shows that interactions between cell assem...

1) This is a great idea.
2) I would be happy to mentor a project like this. If you want to do a project eg at the intersection of Philosophy of Science and NeuroAI, please feel free to reach out to discuss, or just put my name as a suggested mentor!

This is beautiful work and quite the discovery. This also plays nicely with the idea that superficial place cells are rigid and deep are flexible. Seems to suggest that the flexibility is more about past rep's integrating with newer rep's, than the opposite.

The embedding enables a cool experiment: start with a tetrode in CA1 pyr, lower it gradually, and project the signal at each step.
The tetrode follows the predicted path, and the gamma profiles match the silicon probe data beautifully at each step.
See one going from CA1 pyr to DG midmol below!
