|---|---|
| cuneocerebral | ipsilateral subconscious proprioception of neck and UE |
| fasciculus cuneatus | trunk, neck, UE proprioception; vibration, two point discrimination, graphesthesia |
| fasciculus gracilis | trunk, LE proprioception; vibration, two point discrimination, graphesthesia |
| spinocerebellar | ipsilateral subconscious proprioception, muscle tension, joint sense, trunk and LE posture |
| spino-olivary | cutaneous, proprioceptive organ information |
| spinoreticular | level of consciousness from reticular formation |
