142 INTRODUCTION TO NEUROLOGY 



according to Henry Head, protopathic and epicritic functional 

 systems of fibers. As soon as the peripheral nerve-fibers have 

 entered into the spinal cord they are segregated into proprio- 

 ceptive and exteroceptive groups, and each of these again into 

 particular functional tracts. There are connections for local 

 spinal reflexes, reflexes of the brain stem and cerebellum, and 

 for the cerebral cortex. The spino-cerebellar tracts and the 

 dorsal funiculi are proprioceptive in function, and the spinal 

 lemniscus carries spino-thalamic tracts of the systems of touch, 

 temperature, and pain sensibility for the cerebral cortex.
