Sensation from the face travels in one of two pathways both of which eventually converge to form the trigeminothalamic tract that reaches the thalamus. The tract that carries pain and temperature is confusing because it first descends before crossing while the equivalent of Dorsal Column-Medical Lemniscus Pathway carrying vibration, joint position, and fine 2-point discrimination synapses and crosses immediately. The video demonstrates both pathways grossly and with diagrams to its cortical termination.
