Nobody knows, but i imagine that there is not. Not in any real sense. All the major Religions promise that there is something after death, but that is their appeal...and their power.

When we die, our bodies cease to function. Organs stop doing what is required to keep our system ticking along. When the Brain itself dies, we are effectively gone. Just before this point of total shutdown, people can be brought back. Some people have even described the experience. A mixture of chemicals and the progressive turning off of parts of the Brain, seems to generate an internal focus of perception. As signals from the senses are lost, the mind retreats into itself. Signals from the eyes are interpreted as being like a tunnel of light, surrounded by darkness. The mind often imprints images onto this, which it finds appropriate. These images are influenced by a rush of chemicals, which make the last moments of the individual euphoric and peaceful. Some people see Jesus, or Angels, or even a relative. It depends, but all seem to be intended for maximum comfort of the dying individual.

After the Brain shuts down completely, it is hard to say what might happen. Personally, i believe that to be the end of the individual. It is possible that some kind of energy matrix joined to, but seperate from, the organic Brain exists, but there is no real evidence of this. If such a matrix existed, we might survive beyond this life.
