Bigger sensor—less noise

In photography, the bigger the digital camera sensor, the less noise it usually captures. Its pixel size grows to catch more rays of light and improve the image quality.

But our brain is a sensor too. It reacts to different environmental stimuli: visual, auditiv, kinesthetic, gustatorial, olfactorial. We want to extract the most valuable information through our senses with the least effort. In this quest, we are confronted with noise—for example, irrelevant or well-known information.
