The previous is reserved far more for normal non-painful feeling, when the latter is reserved for pain feeling. On reaching the thalamus, the data is processed in the ventral posterior nucleus and sent into the cerebral cortex within the brain by way of fibers during the posterior limb of the internal capsule.
