Can you tell me how much influence does the spinal cord have upon the brain?

Question:
1)A car runs on petrol,a computer on electricty,so what is the power source of the human brain? 2)A car's power source resides in the petrol tank,a computer's in the mains plug/socket,so where does the unit which generates the brains power reside? And how is that power source converted to generate emotions? I mean the emotion of anger is distinctly different from the emotion of sexual arousal.Yet both of these 2 emotions are generated from the same power source. 3)Is it possible to elecit emotions in a person by stimulating them electrically? Is this procedure dangerous/complicated? 4)For much of evolutionary history the brain did not exist, rather there were creatures with just a spinal cord.For this reason,how much influence does the spinal cord have upon the brain? I mean in school we're thought about the hypothalamus's amazing functions, and the amygdala etc.But these structres are evolutionary late comers compared to the spinal cord,have any studies been done as to the role of the spinal cord in generating emotions and thoughts? Could it even be argused that the 'subconcious' resides in the spinal cord? ( PS: you can't feel your own brain,is it possible to feel your spinal cord,sorry if that's a stupid question). 5)People whose spinal cords have been damaged,such that there is no link between it and their brain,how do they feel emotions such as fear and sexual arousal? since the brain generates these emotions,but with the link with the brain broken,how do they travel to the rest of the body to produce the necessay bodily changes,such as increased heart rate,etc etc.

Sugar.

This is the wrong question. There is no "unit" in which the brain's power source resides. The brain consist of cells, each of which are powered by sugar (basically - it's actually a little more complicated than that )

You should also ask what you mean by "emotions" - the word means several different things. The rephrase your questions. But whatever it means, the "power source" of the brain just sustains cell functions. That's all.

Yes, and depends on how you do it. If you stick 'em a couple of electrodes connected to 120V power supply, they will not only be extremely annoyed, they could die. In which case you'll have their relatives to deal with, and a lot of other hassles you don't want.

The spinal cord is involved in certain reflexes. The "sunconscious" isn't a thing that "resides" anywhere.

Fear is a respone that arises in the brain. Sexual arousal is not an emotion but a phsyiological state, which may be triggered by a huge variety of stimuli, making it difficult to control (as I'm sure you've already discovered. ) Some paraplegics can and do have sexual arousals, but I've not discussed sexual feelings or emotions with them. Sorry. Also, you're using the wored "emotion" in at least two different meanings here.
