Bright light stimulates memory and learning, according to research

( Natural News ) The lighting condition in your room affects your brain. Being exposed to bright light boosts memory and learning , according to a new study published in the journal Hippocampus . A group of scientists from Michigan State University carried out a study on the link between lighting and brain structure . In conducting the study, the group examined the brains of Nile grass rats after exposing them to dim and bright lights in a span of four weeks. After they conducted the trials, they found that the rats exposed to bright light exhibited significant improvement on a task that they had trained on in the past, which tested their learning and memory capacity.

On the other hand, the rats exposed to dim light lost around 30 percent of capacity in the hippocampus and poorly performed on the spatial task. The hippocampus is an important region in the brain that is involved in the learning and memory ability of an individual. “When we exposed the rats to dim light, mimicking the cloudy days of Midwestern winters or typical indoor lighting, the animals showed impairments in spatial learning,” said Antonio Nunez, psychology professor and one of the researchers of the study. But when the dim light-exposed rats were then exposed to bright light for four weeks after a break for one month, they fully restored their brain capacity and exhibited better performance on a spatial task. Nunez likened the effect to when people cannot find their way back to their cars in a full parking lot after they spent several hours in a mall or movie theater.
