Painful stimuli can result in responses ranging from itches, to nausea, to simply being in agony. Painful stimuli may be transmitted to the brain by one of two pathways: the [[Sensory Pathways - Anatomy & Physiology#Spinothalamic Tract|Spinothalamic Tract]] or the [[Sensory Pathways - Anatomy & Physiology#Ascending Reticular Formation|Ascending Reticular Formation]].

Pain is not a sensory modality. The sensory modality that is checked in a neurologic exam is Nociception which is the patients response to a noxious stimuli. Pain is a subjective cerebral response. Noxious stimuli can result in responses ranging from itches, to nausea, to simply being in agony. Noxious stimuli may be transmitted to the brain by one of two pathways: the [[Sensory Pathways - Anatomy & Physiology#Spinothalamic Tract|Spinothalamic Tract]] or the [[Sensory Pathways - Anatomy & Physiology#Ascending Reticular Formation|Ascending Reticular Formation]].
