Why Psychology Is The Discipline That is Better Suited To Making A Determination About Whether or Not Consciousness Continues After Death - Not Neuroscience
This is really very simple and very logical; the study of consciousness, and conscious states, and of making determinations about the phenomenological nature of various forms of conscious experience and its relationship to physiology is the domain of psychology, not neuroscience, although neuroscience can play a supportive informational role.
Psychologists are trained not only in recognizing different categories of conscious experience, but also receive training in the neurological/biological and pharmacological aspects that are associated with and can affect conscious experience. Psychologists are trained in the use of various physiological diagnostic tools, like EEGs, MRIs, etc., to aid in their assessments and conclusions about the nature of the reported experiences of their patients. They are trained in the categorical differentiations between various forms of conscious experience using diagnostic criteria.
Neurologists, however, do not have the same kind of training. They are not equipped, by and large, to draw scientific conclusions such as "NDEs are hallucinations produced by the brain." Hallucinations are a well-described and long-studied category of conscious experience, with well-known and well-defined physiological and phenomenological characteristics and well-known causal factors. "Hallucinations," scientifically speaking, is not a "catch-all" bin that people trained in this area of expertise use to just dump all non-ordinary experiences into.
Additionally, there are good reasons why many of the recognized experts in the various fields of afterlife research are often trained psychologists; they are the only people scientifically equipped to develop criteria and protocols necessary to make a determination that consciousness - meaning in this perspective, the personality, memory and behavioral qualities of a "person" as a consciousness - their identity, so to speak - continues on after death beyond their physical body. They are the only ones trained in the criteria of the different categories of experience that can assess whether an experience is better categorized as a "hallucination" or some form of "real-world" experience.
Neurologists are not equipped to make such determinations because their entire area of expertise begins and ends with the physical body. If consciousness exists beyond, after, or without a physical body, neurologists have nothing they can contribute to that discussion. IOW, while neurology can contribute valuable information to the question of whether or not consciousness continues after death, it is really only psychologists that can bring all the necessary resources together to make such a determination and reach well-grounded scientific conclusions about it.
One might argue non-psychologists might, at some point, develop a theory that might produce some technological capacity to "see" into some afterlife domain of existence, and perhaps even "recognize" some dead people and communicate with them; but what kind of discipline would be required to assess whether or not such entities are, in fact, who they appear and perhaps claim to be? Neuroscience would not be of any value either in developing such technology or in making such a determination.
Here is a seminal 2012 paper on Near Death Experiences with extensive citations that illuminates some of the confused areas of NDE misunderstandings that are often the result when scientists who are not equipped with the proper diagnostic training and education in the psychology-based literature make unsupportable claims about NDEs and what they represent and what may be causing them.
