previous outputs or even increase their own previous outputs so you propagate a signal and then maybe this neuron spikes really hard and this Spike's really low then if you propagate the signal again right then you want to match that those those activations or if you if you properly similar signals no feedback required so basically it's a self amplifying or self dampening process the ultimately though you want to learn something about the world and that means you have to have some some feedback from outside right so with
