[{'content': 'Which of the following nuclei is involved in both light reflex and accomodation reflex? \nSelect and explain. \nA. Pretectal nucleus, B. Edinger - Westphal nucleus, C. Suprachiasmatic nucleus, D. Supraoptic nucleus', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Explanation: - Pupillary light reflex: Visual pathway - pretectal nucleus - Edinger Westphal nucleus - constriction of the pupil. NOTE: Pretectal nucleus is connected to E-W nucleus bilaterally, causing contralateral pupil to also constrict (indirect light reflex). Accommodation reaction: Visual pathway - visual coex (blurred image of a near object) - E-W nucleus - changes of accommodation.', 'role': 'assistant'}]
