How much do you know about the Spinocerebellar Tracts?

• There are two spinocerebellar tracts: dorsal and ventral.
• The dorsal tract has uncrossed fibers and causes unilateral loss of subconscious kinesthetic sensation when lesioned on the same side.
• The dorsal tract ascends through other spinal segments and reaches the cerebellum through the inferior cerebellar peduncle.
• The ventral tract contains both crossed and uncrossed fibers.
• The majority of fibers in the ventral tract cross the midline and ascend in the lateral white column of the opposite side.
• Some fibers in the ventral tract ascend in the lateral white column of the same side.
• Lesion of the ventral tract leads to loss of subconscious kinesthetic sensation in the opposite side.
• The ventral tract reaches the cerebellum through the superior cerebellar peduncle.
• Both tracts involve second order neurons.
• The cerebellum receives sensory input from both tracts.
