Neurons do NOT touch one another. There is a gap between them. This gap is the "emptiness" that implies the Imagination that comes from "any" source, internally or externally.
Not exactly Tom. The brain is not like an atom! The neurons are coated by an insulator called myelin which, interestingly, is composed of cholesterol!
“Myelin comprises different cell types and varies in chemical composition and configuration but performs the same insulating function. Myelinated axons are white; hence, the "white matter" of the brain. Myelin insulates axons from electrically charged atoms and molecules. These charged particles (ions) are found in the fluid surrounding the entire nervous system. Under a microscope, myelin looks like strings of sausages.
Cholesterol is an essential component of myelin, which comprises about 40% water; the dry mass comprises between 60% and 75% lipids and between 15% and 25% proteins. Myelin basic protein (MBP) constitutes ~23% of myelin protein, myelin oligodendrocyte glycoprotein, and proteolipid protein (PLP, which makes up ~50% of myelin protein). The primary lipid of myelin is a glycolipid called galactocerebroside. The intertwining hydrocarbon chains of sphingomyelin strengthen the myelin sheath. In brain, the myelin sheath covers the fibers of the corpus callosum, which constitute the inner part of the cerebral hemisphere.”
