Our brain can tell us a lot about ourselves. It can teach us why we feel certain ways about art, and most of these conditions happen unconsciously while viewing art. The human brain works off of a rewards mechanism that is designed to keep us alive, but art can be used to trigger these systems of rewards that exist to make us feel a specific way. The study of what parts of the brain react to different art forms helps us understand how we think and understand.
The art in our world can also tell us a lot about how our brain works. Perhaps the greatest artists understand how the brain works and have created their art to target our human brains. Manipulating us to naturally attach value to art because it forces neurological synapses that we like. Almost as though they are manufacturing a natural drug meant to make us feel certain ways based on pre-existing evolutionary traits. Whatever the case, Neuroaesthetics plays an important role in explaining your brain on art.
This is how science meets art. A scientist can show you a round watch and a square watch. It is more likely that you will like the round one, and that is fine. What does that matter? Exploring the “why” behind our behavior is important because it helps to explain how our brain reacts to different things around us, including (and perhaps most importantly) art.
