Basically, filming people accessing this information for over fifteen years, and visiting the University of Virginia Lab DOPS, where they explore how consciousness is not confined to the brain, I've heard from Dr. Greyson about the "filters on the brain" that seem to be bypassed during the near death event. (See pg 125 of his book AFTER)   Dr. Helen Wambach also talks about "the filters on the brain" in her book RELIVING PAST LIVES.  She also called them "filters that block information not conducive to survival."
Two scientists who talk about the same filters but 50 years apart from different disciplines.  There's also a reference to Viola Pettit-Neal, whom I was turned on to by Harvard neuroscientist Akeera Weerasakera PhD.  She did some trance sessions where she accessed a classroom on the flipside where they talked about the filters on the brain.
People can bypass them using hypnotherapy, mediumship or guided meditation (also with hallucinogens like DMT, in dreams, during near death events, out of body experiences etc.  I recommend using a Newton Institute hypnotherapist, as their four to six hour sessions are like the ones that Dr. Wambach used. (And one can listen to a 2 hour hypnosis session given by Dr. Wambach on this page). 
The point is - anyone can bypass their filters. Mediums don't have the same ones that other folks have, some children don't have them until the 8th year, see people others cannot, recall previous lifetimes.  Some elderly people lose them prior to passing. According to Dr. Greyson's talk IS CONSCIOUSNESS PRODUCED BY THE BRAIN (also reproduced on this page) refers to the data that 70% of the hospice care workers in the UK report dementia patients who spontaneously recall memories - as Greyson notes "It's as if the filters on the brain are dying with the atrophied brain."
In this talk, courtesy of Contact in the Desert, courtesy of Ron Janix who allowed me to film and share this excerpt, this is a simple method of how to bypass those filters. It includes a guided meditation. 
This information is based on fifteen years of filming people accessing the afterlife, accessing their loved ones via hypnotherapy, mediumship and guided meditation.  I was happy to see that the event was standing room only - people lined up along the walls to get some insight into this research.
The reason it's at Contact in the Desert is when people use guided meditation to access their guides (as reported in DIVINE COUNCILS IN THE AFTERLIFE and CLOSE ENCOUNTERS OF THE FLIPSIDE KIND) is because during these simple meditations, sometimes people access beings on their council who have never incarnated on the planet. Further, as noted, in the podcast with Simon Bown (see his podcast #119 ) he accessed a "gray alien" who allowed me to ask him a raft of unusual questions with mind bending answers. (Like: "have you ever donated blood to the Red Cross? The people we visit and extract DNA from are people who offered to donate before they incarnated on the planet.)
I offer this as the kind of research anyone can do - people should see if they get different answers or results from their own experiments... people who do this kind of work can be skeptics, disbelievers, doubters, or religions folks who belief their belief system is sacrosanct.  Data needs to be reproducible and consistent to become data.
In fifteen years of filming people accessing this information - it doesn't change, but keeps getting more interesting, deeper, and mind bending.
 We have a forum at Quora called "Hacking the Afterlife" - it's a place to share data, research or personal experiences with the flipside.
