Researchers in Belgium have established that high levels of lighting can significantly enhance cognitive functions, according to a study published in the journal eLife.
The study involved 26 young participants who were given various tasks, including one where they had to determine if an auditory signal matched another from two signals prior.
Utilising high-resolution functional Magnetic Resonance Imaging (fMRI), the scientists were able to assess how different lighting levels affected the activity in the hypothalamus. Results showed that higher levels of light increased activity in the posterior part of the hypothalamus while lower and anterior parts exhibited a contrary pattern. Moreover, better task performance was notably linked with higher light exposure, suggesting a positive influence on cognitive functions.
The team intends to further explore this area, suggesting that lighting levels could also impact other brain structures.
This research follows findings by scientists in Colombia who identified a gene capable of effectively protecting the brain against Alzheimer’s disease, reducing the risk of dementia by 70 percent.
