[{'content': 'The increase in the threshold of a receptor when a series of stimuli of subthreshold intensity are applied in succession is called \nSelect and explain. \nA. Adaptation, B. Accomodation, C. Initiation, D. Resistance', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Accommodation\xa0- Slow rising subthreshold stimulus failing to produce action potential even when the normal threshold levels are reached. \nThis occurs because of inactivation of voltage-gated Na+ channels. \nAdaptation- Persistent application of suprathreshold stimulus fails to generate repetitive firing.', 'role': 'assistant'}]
