The trigeminocardiac reflex (TCR) is a well-established brain stem reflex. Since it was first described by Schaller in 1999, the TCR has gone from being considered an episodic occurrence to becoming known as one of the most important phenomena ever seen in a number of different neurosurgical procedures, especially skull-base surgery. 1.; 2.; 3.; 4.
Doctors will typically grade the activity of a reflex on a scale from 0 to 4. While 2+ is considered normal, some healthy individuals are hypo-reflexive and register all reflexes at 1+, while others are hyper-reflexive and register all reflexes at 3+.any of these reflexes are quite complex requiring a number of synapses in a number of different nuclei in the CNS (e.g., the escape reflex). Others of these involve just a couple of synapses to function (e.g., the withdrawal reflex).
