In the nervous system, the anterolateral system is an ascending pathway that conveys pain, temperature (protopathic sensation), and crude touch from the periphery to the brain. It comprises three main pathways:
Name | Destination | Function |
spinothalamic tract (lateral and anterior) | thalamus | important in the localization of painful or thermal stimuli |
spinoreticular tract | reticular formation | causes alertness and arousal in response to painful stimuli |
spinotectal tract | tectum | orients the eyes and head towards the stimuli |
