Breathing before a brushstroke
Do you take a deep breath before you make a stroke of your brush or pen? Many of the old lettering and painting manuals advise the artist to breathe in before beginning a difficult mark.
There may be a reason, according to a recent scientific paper. Your brain function alters with every inhalation and exhalation. It's a holdover from our sense of smell, one of our most primal senses.
It turns out our breathing in and breathing out is synchronized in lock-step with our cognitive activity. This is true not only for olfactory processing, but also for visual and spatial processing.
From the abstract: "We measured nasal airflow and electroencephalography during various non-olfactory cognitive tasks. We observed that participants spontaneously inhale at non-olfactory cognitive task onset and that such inhalations shift brain functional network architecture. Concentrating on visuospatial perception, we observed that nasal inhalation drove increased task-related brain activity in specific task-related brain regions and resulted in improved performance accuracy in the visuospatial task."This makes sense to me. Breathing skills are fundamental to so many art disciplines. After all, the word "inspiration" literally means breathing in. I wonder if the connection between inhalation and brain activity is more than just a link to an ancestral olfactory system, but also an unconscious desire to oxygenate the brain at the onset of increased cognitive load?
