Altered states of consciousness

Posted by

It is argued that altered states, which can result from a range of cause including near-death-experience (NDE), meditation or psychedelic drugs, can be directly causal of durable personality changes.

Thus contrary to any suggestion that the self is some type of ‘mystical illusion’ it may in fact be part of a system that constrains ‘mystical’ experience during normal brain processing.

Neural correlates of the psychedelic state as determined by fMRI studies with psilocybin www.pnas.org/cgi/doi/10.1073/pnas.1119598109 This paper further undermines the persistent claim within mainstream consciousness studies that all that needs to be done is to deconstruct the self (a relatively easy process) and then declare the consciousness problem solved. Altered states of consciousness have always appeared to contradict this claim, but the evidence of this was at a rather anecdotal level. Read more […]
