Hi Ousaima,
1. We often see stomach ulcers or gall bladder ache in people who have an aggressive attitude, or have a hard time to suppress it when they are angry, that's why they may take to aggression against self (like biting nails or scratching/cutting their skin.And I think that the physical irritability also can aggravate this behaviour.
2. Can you refer to the time I name this in the video please? 
3. In cerebral cortex related organs, healing peak reactions are typically very short, a seizure or a "spacing out" moment. Loss of memory, or typical dementia, follows several separation/loss of touch traumas, and in these cases there is scarring or placque accumulating in the affected brain regions.
4. You refer to the territorial areas in a special part of the cerebral cortex, right? In this part, the "insula", the side dominance doesn't refer to partner/child eye-level distinction, but to the priority of male or female attributes and behaviour, and these relays are also influencing the release of sexual hormones. Let's talk about these when we come over the territorial constellations, which reveal our personality and typical ways of interacting in groups
