Detailed explanation-1: -The dorsal spinocerebellar tract (Flechsig’s tract) is located at the dorsal part of the lateral funiculus, adjacent to the lateral corticospinal tract. It is formed by axons of the ipsilateral dorsal nucleus (Clarke’s column), present in T1–L2 segments in humans (Smith, 1976).
Detailed explanation-2: -These peduncles are superior, middle and inferior. Superior cerebellum connects cerebellum to the midbrain, middle to the pons and inferior to the medulla oblongata. Superior cerebellar peduncle (brachium conjunctivum) ascends upward from the anterior cerebellar notch to the tectum of the midbrain.
Detailed explanation-3: -The superior cerebellar peduncle contains vital afferent and efferent fibres including cerebellothalamic, cerebellorubral and ventrospinocerebellar tracts.
