What is the reticular formation (RF)?
What will be an ideal response?
The reticular formation (RF) consists of a bundle of approximately 90 separate nuclei that run like a cord through the middle of the brain stem upwards into the diencephalon. This network of neurons forms both ascending and descending pathways relaying important sensory and motor information between the brain and body. Sensory information from the periphery is relayed in the brain's ascending pathway through the RF into the thalamus where it is gated to determine if it will be passed on to the neocortex as part of the sensory projection system. It is through the RF that the hypothalamus sends descending signals to the brain stem and the viscera to activate the autonomically mediated fight-or-flight response. The RF was also involved in rousing you from your slumber when you heard the loud noise at your window.
