The brain exhibits initial 'noise' when performing a task, which clears to a strong signal with repetition, indicating attractor state formation.

“What you see is there's a lot of noise, what we call a lot of hash, not not the kind people smoke, but it's like it sounds like on the audio monitor as they repeat the task over and over that the signal becomes very very clear and you haven't made any adjustments to the equipment. Sometimes you have and you start getting great signal to noise because the circuit just it's these attractor states and that the signal to noise goes way way up.”
