"Manufacturing these chemicals, and dispersing them to regulate and modulate brain activity, requires energy -- neurons are living cells with a metabolism, and they get that energy from glucose. No other tissue in the body relies solely on glucose for energy except the testes. (This is why men occasionally experience a battle for resources between their brains and their glands.)"
I think what he is saying is that both the brain and the testes rely solely on glucose for energy. I don't know if this is true or not.
I think calling them "tissues," when they are really organs (albeit composed of tissues) and calling the testes (plural) a tissue (singular) is sloppy writing. He "is an American-Canadian cognitive psychologist, neuroscientist, writer, musician, and record producer," according to
Wikipedia, so he should know what he is talking about.
