News Finding: "This research is the perfect example of how a fortuitous discovery can redefine our understanding of the world around us," said van Doorn.
Paper Finding: there was no constriction or emptying of the blood vessels.
News Context: Together, these experiments show the relationship between environmental stimuli and vision, as well as highlight the interesting and complex effect blood flow patterns have on visual clarity. Future research will investigate the mechanism underlying this relationship. "This research is the perfect example of how a fortuitous discovery can redefine our understanding of the world around us," said van Doorn.
Paper Context: During the renewal phase of the integument, spectacle blood flow was found to remain constant when the snakes were undisturbedi.e. there was no constriction or emptying of the blood vessels. When the snakes were handled or otherwise disturbed, blood flow would slow or stop for brief periods of the order of 1-10s, but the spectacle blood vessels remained fully dilated and did not empty.
