Which tract transmits sensory information about vibration?

Explanation:
Vibration is carried by the dorsal (posterior) column–medial lemniscus pathway. These columns convey fine touch, vibration, two-point discrimination, and proprioception from the body, ascending ipsilaterally to the medulla where they synapse and then relay through the thalamus to the cortex. The spinothalamic tract carries pain and temperature, not vibration, which is why it isn’t correct. Proprioception is part of the same dorsal column system, but the tract best described for vibration is the posterior column.
