Spinal cord Quote by Anonymous

““At the present, a plausible nominee for the neural substrate of consciousness is one of the most important neurological discoveries of our time. T h is is that tangle of tiny internuncial neurons called the reticular formation, which has long lain hidden and unsuspected in the brainstem. It extends f rom the top of the spinal cord through the brainstem on up into the thalamus and hypothalamus, attracting collaterals from sensory and motor nerves, almost like a system of wire-tabs on the communication lines that pass near it. But this is not all. It also has direct lines of command to half a dozen major areas of the cortex and probably all the nuclei of the brainstem, as we ll as sending fibers down the spinal cord where it influences the peripheral sensory and motor systems. Its function is to sensitize or “awaken” selected nervous circuits and desensitize others, such that those who pioneered in this work christened it “ t he waking b r a i n””
