An experimental-anatomical study on the spinothalamic tract in the cat.

Much has been written concerning the spinothalamic tract in the rabbit, monkey and man. However, many early and more recent investigators using the cat have not been able to trace this tract to the thalamus by the Marchi method (P a t r i k, '93, '96 ; Chang and R u c h, '47 ; Morin et al., '52). In recent years silver techniques have been widely utilized in demonstrating precise fiber connections of the brain and spinal cord. Getz ('52) demonstrated terminal degeneration in the thalamus by the Glees method following cordotomy in the cat. Thereafter, Morin and Thomas ('55), N aut a and Kuypers ('58), Anderson and Berry ('59) and Terada
