This is my declared new quest, a very important one, as I was told by somebody who cares about it.
And this, at the age of fifty!
I must honestly admit, I did not expect that somebody would ever ask me anxiously on this matter.
A healthy craziness begins!
"Amygdala
The amygdala (Latin, corpus amygdaloideum) is an almond-shape set of neurons located deep in the brain's medial temporal lobe.Shown to play a key role in the processsing of emotions, the amygdala forms part of the limbic system.In humans and other animals, this subcortical brain structure is linked to both fear responses and pleasure.Its size is positively correlated with aggressive behavior across species. In humans, it is the most sexually-dimorphic brain structure, and shrinks by more than 30% in males upon castration.Conditions such as anxiety, autism, depression, post-traumatic
stress disorder, and phobias are suspected of being linked to abnormal
functioning of the amygdala, owing to damage, developmental problems, or
neurotransmitter imbalance.
