Where is the reticular formation? What is its purpose?
Reticular formation is located within the midbrain, pons, medulla, thalamus and hypothalamus. It is activated in a non-specific fashion by sensory information, its fibers project diffusely and result in non-specific arousal of the cortex to incoming sensory info. Its continuous transmissions activate the brain. There's no brain function without it. It's the core of the CNS. It organizes basic behavioral patterns involving the body as a whole.
It adds method to the madness.
