![]() ![]() ![]() Jimo Borjigin, a neuroscientist at the University of Michigan, first became intrigued by this subject when she noticed something strange in the brains of animals in another experiment: Just before the animals died, neurochemicals in the brain suddenly surged. “And so that’s where people begin to see light.”Recent research points to evidence that the sharpening of the senses some people report also seems to match what we know about the brain’s response to dying. ![]() He compares the breakdown to what happens in aging: People tend to lose their abilities for complex or executive planning, learning motor skills-and, in what turns out to be a very important function, inhibition.“As the brain begins to change and start to die, different parts become excited, and one of the parts that becomes excited is the visual system,” Hovda explains. Is the person sleeping, dreaming, experiencing something supernatural? Is her mind gone?For many dying people, “the brain does the same thing that the body does in that it starts to sacrifice areas which are less critical to survival,” says David Hovda, director of the UCLA Brain Injury Research Center.
