Lemniscus spinalis is a term that is now often applied to the brain stem and is another name for the parts within the so-called anterolateral pathway system that convey pain and temperature from the opposite half of the body up to the thalamus.
The part of the anterolateral pathway system which mediates "crossed" diffuse pressure and touch sensation (tractus spinothalamicus anterior), and which in the spinal cord is more or less mixed with the pain- and temperature-mediating part (tractus spino-thalamicus lateralis), it joins in the medulla the medulla of the medulla.
Calculated from the ponslevel, the spinal limbic also contains pain and temperature information from the opposite half of the face mediated via threads from the spinal trigeminal nucleus.
