This Mothers Day post was motivated by Dachshund's comment to Why People Work Hard (below intro)
It is a brief snippets exploration into the possible neurological (psychological and emotional) foundations of love, from the perspective of individuals whose 'love' thinking and behaviour, occurs at the level of the reptilian brain, limbic brain, or neocortex.
All mammals have reptilian, limbic and neocortex brains; Reptiles only have reptilian brains. In any mammal, any 'fight, flight, love, et al' behaviour may be rooted in any related, or a combination thereof brain. Additionally the practice of certain behaviours, in this case, love, touch and intimacy, from infancy all through life stimulates the growth and activity and intimacy in the limbic brain. The absence of loving touch, and intimacy from childhood, results in stunted limbic brains. A mammal/human with a stunted limbic brain, accordingly responds to 'love' by means of their reptilian brain knowledge thereof.
Reptilian brains experience a reptilian truth: "no intrinsic restraint on harming people exists in the reptilian brain."
