Effects of Neuroplasticity in Emotion Regulation

In a recent interesting project done by Giuliani NR et al (Guiliani NR, et al, Emotion Regulation and Brain Plasticity: Expressive Suppression use predicts anterior insula volume Neuroimage; 2011 58(1) 10-15), they showed that expressive suppression of emotion, significantly increases the volume of the left anterior insula. Interestingly they also found that cognitive reappraisal and negative affect do not produce such a change. Even if the latest two emotional states are similar to emotion suppression, the effect on brain volume was different.

This corroborates my thinking mentioned in a previous blog entry, that neuroplasticity and bran fitness are very specific to a particular brain circuit. By training a particular brain circuit with a specific activity this should not interfere with another brain circuit.

In my opinion brain fitness will generalize only to the activities related to the brain circuit particularly trained.
