The 'reticulospinal tract' (or 'anterior reticulospinal tract') is an extrapyramidal motor tract which travels from the reticular formation.
The sensory tract conveying information in the opposite direction is known as the "spinoreticular tract".
The tract is divided into two parts, the medial and lateral reticulospinal tracts (MRST and LRST). The MRST is caudal to the Superior Colliculus and is responsible for extensor muscles. The LRST is rostral to the Superior Colliculus and is responsible for the flexor muscles. If the Superior Colliculus is damaged, it is called decerebration and causes decerebate rigidity.
