Last year, a team led by Harvard Medical School genetics professor Susan Dymecki defined a subgroup of serotonergic neurons in mice by showing that those cells specifically, among all serotonergic neurons, were responsible for increasing the breathing rate when too much carbon
dioxide builds up in the body.
And the first thing that begins to happen is carbon
dioxide builds up inside the
body, and with it there is a rise
in acidity; that acidity rise contributes to cellular membranes decaying and then collapsing and then digestive enzymes that were already always present
in the cells begin to slosh around to the
body and [it] begins a state of what's called self digestion, so the
body begins to liquefy inside rather literally.
