Each cell sends electrical pulses to other cells, up to hundreds of times per second. If you represented each of these trillions and trillions of pulses in your brain by a single photon of light, the combined output would be blinding. (David Eagleman)

The cells and fibers of the brain must carry some kind of individual identification tags, presumably cytochemical in nature, by which they are distinguished one from another almost, in many regions, to the level of the single neurons.

The poem you sent me was as fiery and virile as anything you've ever written – or anybody else, for that matter. Especially the second part went to my brain like the flaming liquor of insanity. No one else besides Jack London has the power to move me just that way.

Aldous Huxley took the drug mescaline and then chronicled his experience in the book The Doors of Perception. Now, I don't actually think that's the first thing he wrote: he probably wrote 'my brain is melting' ten thousand times, but it was the book that the critics latched on to.
