Visual stimulation increases regional cerebral blood flow and metabolism in the goldfish.
Studies with radioactive antipyrene and deoxyglucose indicated that both blood flow and metabolism are enhanced in the goldfish optic tectum following a brief visual stimulation. It is concluded that the brain of cold-blooded animals demonstrates regionally regulated physiological alterations, previously reported only in warm-blooded species.
