I think one of the difficulties is that we tend to think of our consciousness as singular, when in fact it is 'made' of multiple interacting systems. When my limbic system/amygdala process their information, *I* feel the feelings. When the frontal and prefrontal cortex plans or regulates, *I* am planning and regulating. There isn't a 'special circuit' for consciousness. Instead, it appears that consciousness is the whole shebang: the whole interacting collection.
Memories are retained in a variety of brain systems. Damage to the amygdala, for example, will destroy the ability to form short-term memories. But more complex, long-term memories are often 'stored' in the frontal areas.
In what form, if any, in your opinion/belief, do feelings and emotions transcend death of the human form and the brain? Are the retained as memories of these emotions and feelings, or actual emotions ad feelings? Or are the not retained at all?
(This question and the one in the final paragraph of my preceding post are for anyone to respond to, not just @Polymath257.)
