The brain is fascinating, I just wish we could work out what it really needs to be happy. We were apes but we are more than that now, with very complex needs. Sometimes it feels like evolution has created a monster, one that is never satisfied, never content, you know?
I guess with survival of the fittest being the primary force moving evolution happiness and contentment are not in the dynamics.
The way I see it a sort of rewiring must take place and the Amygdala is the most important place to start IMO.
https://en.wikipedia.org/wiki/Amygdala
The amygdala (/əˈmɪɡdələ/; plural: amygdalae; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil'[1]) is one of two almond-shaped groups of nuclei located deep and medially within the temporal lobes of the brain in complex vertebrates, including humans.[2] Shown in research to perform a primary role in the processing of memory, decision-making and emotional responses, the amygdalae are considered part of the limbic system.[3]
Hemispheric specializations[edit] There are functional differences between the right and left amygdala. In one study, electrical stimulations of the right amygdala induced negative emotions, especially fear and sadness. In contrast, stimulation of the left amygdala was able to induce either pleasant (happiness) or unpleasant (fear, anxiety, sadness) emotions.[9] Other evidence suggests that the left amygdala plays a role in the brain's reward system.[10]
Each side holds a specific function in how we perceive and process emotion. The right and left portions of the amygdala have independent memory systems, but work together to store, encode, and interpret emotion.
The right hemisphere is associated with negative emotion. It plays a role in the expression of fear and in the processing of fear-inducing stimuli. Fear conditioning, which is when a neutral stimulus acquires aversive properties, occurs within the right hemisphere. When an individual is presented with a conditioned, aversive stimulus, it is processed within the right amygdala, producing an unpleasant or fearful response. This emotional response conditions the individual to avoid fear-inducing stimuli.
