Make the Mona Lisa smile
Leonardo believed that emotions were processed in a part of the brain
called sensus communis. Find out how this affected Mona Lisa’s
emotional side.

Leonardo believed that the soul was tucked away in the same part of the brain as the sensus communis
(where sensory information was compared). It was here that fantasy,
imagination and dull old intellectual reason fought it out for control
of our emotions.
In reality, we are not yet entirely certain which parts of the brain
control our emotions. Current thinking (which is science-speak for
“best guess”) suggests that our emotional responses are controlled by
several different parts of the brain.
The area of the brain directly behind the forehead and above the
eyes (the prefrontal cortex) is where we grown-ups anticipate the
consequences of our actions, and so it helps us to control our
emotions. Just behind this area is another region (the anterior
cingulate cortex), which is where we decide where we will direct our
attention. This in turn governs our emotional awareness.
Perhaps the most interesting part of the emotional brain, and the
bit that has made all of us turn our noses up in disgust at some time
or other, is the insular cortex. This connects emotions to other parts
of the brain which control heart rate, breathing and digestion and so
plays a big role in telling us if things taste good, bad or simply
yuck!
