Eternal oblivion (also referred to as non-existence or nothingness)[1][2] is the philosophical, religious, or scientific concept of one's consciousness forever ceasing upon death. Pamela Health and Jon Klimo write that this concept is mostly associated with religious skepticism, secular humanism, nihilism, agnosticism, and atheism.[3] According to most modern neuroscience theories of consciousness, the brain is the basis of subjective experience, agency, self-awareness, and awareness of the surrounding natural world. When brain death occurs, all brain function forever ceases.[4]
Many neuroscientists and neurophilosophers, such as Daniel Dennett, believe that consciousness is dependent upon the functioning of the brain and death is a cessation of consciousness. Scientific research has discovered that some areas of the brain, like the reticular activating system or the thalamus, appear to be necessary for consciousness because dysfunction of or damage to these structures causes a loss of consciousness.[5] Through a naturalist analysis of the mind, it is regarded as being dependent on the brain, as shown from the various effects of brain damage.[6]
