That is, conscious decisions are said to be regulated by the prefrontal cortex, whereas inherited reactions (fear of snakes, etc.) are more regulated by the hypothalamus and the amygdala. (Yes, I am aware that this is something of a simplification, but this is valid enough for my question, I believe.) Learned reactions (how to react to steer a bicycle, etc.), which are learned by conscious decision but can act just like an inherited reaction, are somewhere in-between. So which part of the brain regulates them?
