And yes, they do need to take the whole thing: taking a small sliver won't give doctors a full picture of what happened, which tends to be the problem with diagnosing from biopsies (small bits of tissue taken from living people). “After death the composition of the bacteria changes,” says Javan. Then, rigor mortis – “the stiffness of death” – sets in, starting in the eyelids, jaw and neck muscles, before working its way into the trunk and then the limbs.

Our bodies host huge numbers of bacteria; every one of the body’s surfaces and corners provides a habitat for a specialised microbial community. The body is conserving the little energy it has, and as a result, needs less nourishment and sustenance. Javan’s study suggests that this ‘microbial clock’ may be ticking within the decomposing human body, too. Essentially, you may "wake up" extremely briefly after death â using a large amount of the neural connections depicted in the image above, which was generated by researchers at Brown University to depict the ways our brains function. The researchers were able to estimate time of death to within three days of a nearly two-month period.
