The cortex relies on the basal ganglia to make decisions about withholding or executing behavior.

“the cortex can't really do what it needs to do without the help of the basil ganglia and vice versa. And in a way you can think about this logically as saying, you know, if if you have the ability to withhold behavior or to execute it, how do you decide which to do? Well, the cortex is going to have to do that thinking for you. You have to be looking at all the contingencies of your situation and decide, is this a crazy move or is this a really smart investment right now or you know what, right?”
