WebMay 5, 2015 · Somatic sensory pathways. Two major spinal cord pathways carry sensory information to the cerebral cortex where it can be consciously perceived. The dorsal column pathway is concerned with precisely localized touch and joint position sense. The spinothalamic tract is primarily responsible for pain and temperature sensation. WebThe sensory pathways that deliver pain and temperature information to the brain are each composed of a receptor and three successive neurons.
