<P> Although it may seem that the sun is the brightest spot on the canvas, it is in fact, when measured with a photometer, the same brightness (or luminance) as the sky . Dr. Margaret Livingstone, a professor of neurobiology at Harvard University, said "If you make a black and white copy of Impression: Sunrise, the Sun disappears (almost) entirely ." </P> <P> Livingstone said that this caused the painting to have a very realistic quality, as the older part of the visual cortex in the brain--shared with the majority of other mammals--registers only luminance and not colour, so that the sun in the painting would be invisible to it, while it is just the newer part of the visual cortex--only found in humans and other primates--which perceives colour . </P> <P> Most critics did not think Impression, Sunrise was one of the most notable pieces; it was briefly discussed only five times in all the reviews of the exhibition . However, the reviews of the exhibition and of Monet's painting both provide insight into the development of the movement and Monet's work and development as an artist . </P> <P> Philippe Burty for La République Française wrote about the opening of the show, complementing the ambiance of the space and the paintings working together: "The walls of the rooms, covered in brownish red woolen fabric, are extremely well suited to paintings . The daylight enters the rooms from the sides, as it does in apartments ." </P>

Where was the impression sunrise until it was stolen
