Affective wellbeing or happiness is not a specific cerebral circuit. It is a state of low cerebral energy consumption that is based on reversible and efficient neuronal functioning.  The search for neuronal energy efficiency – and, consequently, their reversibility – is the basis for emotional learning.

Problem: When affective wellbeing or happiness are missing, the brain can consume up to ten times more than it should.  In other words, 20%* with regard to body consumption, given that certain behaviours arise that prevent neuronal reversibility and consequently the brain consumes more.  Then the person enters a state of unlearning.

Conclusion: The reversible and efficient functioning of neurons is reached when all of our relationships are directed at the wellbeing of those closest to us.  Then levels of 2%** or less of consumptions could be reached, with regard to body consumption.  Therefore the way we relate to one another is a key tool in influencing emotional learning and affective wellbeing or personal happiness.
