Life after death is something we fear about. Whether it be someone who is religious or an atheist, the fact that we don’t know what happen after we die is quite frightening.
Some people who have near death experiences or out of body experiences have claimed to experience a bright tunnel or their lives flashing before their eyes.
Scientists argue that in the state of trauma (such as near death experience) the pineal gland releases a strong psychedelic chemical known as DMT which can cause these experiences.
But what is just confusing is the similarity between people’s experiences. Does all ‘DMT trips’ result in the same hallucinations? Or are these chemicals just a glimpse into the world beyond.
Here is what happens to your brain just before 30 seconds you die.
What separates humans from other animals is not mere brain size but also its efficiency and capability. The folds or wrinkles of the human brain are what creates the superior (when compared to other animals) ‘processing power’ of the human brain. The folds allow for more surface area in a compact space thus creating more power.
Animals such as elephants and primates have an evidence of the folds in their cranium thus indicating a higher intelligence. Dolphins, in fact, have more wrinkles in their brains than humans, which can explain their capacity for altruism and language.
What is important to note is that modern human brain has decreased in size. Compared to our ancestors our brains have actually shrunk by approximately 10 percent. This does not mean that our ancestors were smarter and we have evolved into sub-par beings, rather this can be a sign that evolution is making our brains more efficient.
There are some controversies as to the origins of the huge jump in brain capacity in the human history. Some anthropologists argue that consumption of meat created this huge jump in brain capacity while others argue that it is due to social competition, the demands of ecology or climate change.
In an interview, neurologist Brian Shaw showcased with a cadaver how the human brain functions just before death. He says that typically the human brain dies from the top down. The more up from the brain stem we go, the more advanced human characteristics we see.Things such as awareness, consciousness and our individual personalities as dictated by the frontal lobes tend to go first. Thus, in death, it is most likely that the most human characteristics will go first.

“Our sense of self, our sense of humour, our ability to think ahead — that stuff all goes within the first 10 to 20 seconds. Then, as the wave of blood-starved brain cells spread out, our memories and language centres short out, until we’re left with just a core,” Brian said.
This means that as our mental faculties deteriorate until what remains is our primitive mind. The ability to breathe, regulate body temperature, control cholesterol are just a few of the functions that are conducted in this primitive state.
As the brain continues to shut down, higher functions begin to fade and only basal structures remain. These structures help keep your organs running and blood pumping, but in brain-dead situations, sometimes blood doesn’t even pump properly thus machines need to be employed in order to get the blood flowing to the right places.
