[{'content': 'In the cross section of brain in the below pic, the tracts have been labeled, which of them are concerned with pain and temperature. \nSelect and explain. \nA. B, B. C, C. A, D. S and T of C', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Pain and temperature are carried by the spinothalamic tract (STT) towards the VPL (ventro-postero-lateral) nucleus of\xa0thalamus.\n\nPain is carried by the lateral STT whereas anterior STT carries the crude touch sensations.\nSpinothalamic tracts carry sensations contra-laterally hence the area of sensation loss is to the opposite side of the lesion (Brown-Séquard syndrome).\nSpinocerebellar tracts carry the unconscious proprioception, mainly from the lower limbs, towards the cerebellum and from the mossy fibers. They contribute\xa0archi-cerebellar\xa0fibers to the cerebellum.\nDorsal spinocerebellar fibers carry the information ipsilaterally and enter the inferior cerebellar peduncle to reach the cerebellum.\nVentral spinocerebellar tract carries the information contra-laterally and enters the cerebellum via superior cerebellar\xa0peducle.\nUnconscious proprioception of\xa0upper\xa0limb is carried by the cuneocerebellar tract.\nConscious proprioception is carried by the dorsal columns (Fasciculus\xa0gracilis\xa0and\xa0cuneatus).\nPyramidal tract is a motor tract and is concerned with control of fine and skilled voluntary motor activity.', 'role': 'assistant'}]
