[{'content': 'Vibration sense is carried by which pathway? \nSelect and explain. \nA. Ventral spinothalamic, B. Lateral spinothalamic, C. Dorsal columns, D. Anterolateral pathway', 'role': 'user'}, {'content': 'Answer: C \nExplanation: (C) Dorsal columns > A pattern of rhythmic pressure stimuli is interpreted as vibration.> The impulses responsible for the vibrating sensation are carried in the dorsal columns.> Degeneration of this part of the spinal cord occurs in poorly controlled diabetes, pernicious anemia, some vitamin deficiencies and occasionally other conditions; elevation of the threshold for vibratory stimuli is an early symptom of this degeneration.> Vibratory sensation and proprioception are closely related; when one is depressed, so is the other.', 'role': 'assistant'}]
