implies certain kinds of correlational structures that we can start to look at we also have the ability to image synapses in the two-photon image of the synapses differently separately from the cell body so we can actually look at feedback synapses specifically and ask how the information that they contained is different than the the cell bodies in layer 2 3 so these are all experiments that are ongoing but I don't have a good answer for you but that's the right kind of question and that's the right kind of question we can ask you know when we
