Read synaptic self by Jason LaDuex[0], the leading theory for the last 20+ Years in the neuroscience field is that our consciousness is a sort of a reverb of electric signals between synapses. Rather than engaging in decisional thought, we are merely reacting to our environment and we think our decisions are ours but instead it’s the reverb during the delay of the electrical impulse to our muscles. So when you think “ I want to get off the couch”, your brain has already made the decision and your thought is occurring while the electrical signals are traveling to the necessary muscles to move.

Ends the idea of free-will, but considering we are all just chemical reactions at the biological level, makes sense..
