Y1 - 2020 N1 - T2 - Clinical Neuroanatomy, 29e AB - The neural basis for consciousness has fascinated scientists and philosophers for centuries. The reticular formation of the brain was recognized in the 1950s as a master regulation of consciousness. The reticular formation plays a central role in the regulation of the state of consciousness and arousal. It consists of a complex network of interconnected circuits of neurons in the tegmentum of the brain stem, the lateral hypothalamic area, and the medial, intralaminar, and reticular nuclei of the thalamus (Fig 18–1). Many of these neurons are serotonergic (using serotonin as their neurotransmitter), or noradrenergic. Axons from these nonspecific thalamic nuclei project to most of the cerebral cortex, where they modulate the level of activity of large numbers of neurons.
