The importance of ‘seeing’ the shadows of light
2001/05/21 Elhuyar Zientzia
As published on the website of the journal Nature, according to a study with mice, a pigment in the eyes of mammals allows to regulate functions related to light shadows.
Apparently, this pigment is sensitive to light, so blind mice are also able to distinguish day and night and retain functions and behaviors related to light level, such as circadian rhythm or eating hours.
In fact, if only the detection of luminosity changes depended on the cones and canes of the retina, a ray that breaks the darkness of the night would be enough to restore the body clock.
