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.
Best Answer: Monosynaptic reflexes such as the patellar reflex do not involve the brain since no intermediate (relay) neurone is involved. Other polysynaptic reflexes do involve the brain since a relay neurone is involved in the reflex arc which connects with longitudinal neurones running to and from the brain.You cannot suppress a monosynaptic reflex but you can suppress a polysynaptic reflex due the involvement of the brain.Source(s):eport Abuse. No it is not! The reflex arc works from the sensory neuron to the spinal cord, then directly to a motor neuron to perform the 'reflex.' The brain has no idea until the message then travels from the reflex action through another sensory neuron back to the brain to inform it of what just happened.
