Thank you guys for taking part in the discussion, you shifted the topic a little, so I want to place a more specific question. Do you agree that without emotion there can't be any motivation, and without motivation there can't be any willpower?
The real problem here is that you want to break the mind/brain down into a collection of separate functions or components, and the essence of mental processing is how a whole lot of activity hangs together.
To do science, we must chunk the description in some way. But we have to be very careful to do so in a way that cuts with the grain as much as possible.
Emotion, motivation, drive, will power, free will, are a bunch of folk pyschology concepts that are created culturally to explain the mind in terms that help teach the right kinds of moral and ethical lessons. They are not scientifically-based, and so lead to all sorts of confusion.
They sort of mean something, but they are not precise terms that can be related to the neurology or even the psychology.
A general point to make is that the brain is designed to react to everything "emotionally" - to value the world. And everything it focuses on will also be "motivating" - lead to some state of action and intention. This is true even if the response is to feel relaxed, to lie down and save energy.
So every moment of awareness forming involves a valuing and an intending.
Then we can make a distinction between endogenous and exogenous focus. Different neurotransmitter systems are involved so it is a fairly strong distinction. Depending on the balance of threats, opportunities and intentions prevailing, we can either be more outwardly alert an uncommitted, or more inwardly focused on a train of goals and actions.
So this balancing act between being driven by outer events or inner desires/intentions is what we are getting at when we talk about the socialised conflict between our will and our distractions.
To answer your question, there cannot be brain activity without evaluation and so emotion - changes in the state of the brain and body to suit the perceived or anticipated circumstances. And there cannot be attentive awareness without some thought of a response.
There is a major choice we are constantly making between following our own internal agendas and responding to the events imposed upon us by circumstances.
For animals, their brains have evolved to make these choices very efficiently and we can follow the neural story nicely.
For humans, we have this neural machinery, but also overlaid are the socialised habits. In effect, we carry around a really big internal cultural agenda - an extra lens - through which we view life and make those internal vs environment valuing and acting decisions.
