11. This is how the reticular formation mediates attention and wakefulness. 12. It terminates in the brainstem at the medullary-pontine reticular formation. 13. The canal system is reticular , characteristic of the Wutinoceratidae. 14. Symptoms within this classification include the startle response and reticular reflex myoclonus. 15. Both regions are components of the reticular activating system ( RAS ). 16. The hindwings have a similar reticular pattern and a white anal area. 17. Modern scientists usually refer to the individual nuclei that comprise the reticular formation. 18. Mitochondria routinely undergo fission and fusion events that maintain a dynamic reticular network. 19. Reticular reflex myoclonus is a generalized form of epilepsy originating from the brain stem.20. The thalamic reticular nucleus, when active, inhibits the sensory nucleus with GABA.
