Essentially silent in sleep', 'role': 'user'}, {'content': 'Answer: C \nExplanation: The vasomotor centre receives inputs from cortex directly and indirectly through the hypothalamus.

BP is regulated by medulla through the vasomotor centre (sympathetic centre) and cardioinhibitory centre (parasympathetic centre), which acts together.', 'role': 'assistant'}]
