claim with evidence

• Consciousness does not become annihilated just because a person has just died
• Consciousness appears to continue at least in the first period the early period of death the first minutes or hours after death
• Explanation
  • death is a biological process
  • when you stop blood flow to brain cells they undergo certain changes and will eventually become damaged
  • however the first thing that happens is that you stop oxygen delivery to the areas inside the core of the brain that modulate your sense of being awake and alert
  • the reticulate activating system various other parts and so it's very similar to the effect of giving a general anesthetics to somebody
  • if you give a high enough dose of general anesthetic to a patient or person then you basically shut down those areas of the brain
  • the person's consciousness looks like it's lost
  • it flips out of sight but we wouldn't say that person's Consciousness has become annihilated forever
  • we just realize it's gone temporarily and so when people first die what's happening is that oxygen is stopping to those parts of the brain and it's essentially taking Consciousness out of you and making it disappear but it doesn't necessarily disappear Forever

comment

• could this be the reason in Tibetan Buddhism, there is the Thukdam meditation practice as well as dream yoga practice?
