Research on Experiences Related to the Possibility of Consciousness Beyond the Brain: A Bibliometric Analysis of Global Scientific Output.

This study aims to conduct a search of publications investigating experiences commonly associated with the possibility of the existence of a consciousness independent of the brain held on the main scientific databases (Pubmed, Web of Knowledge, PsycINFO, Science Direct, and Scopus). Of the 9065 articles retrieved, 1954 were included (598 near-death experiences, 223 out-of-body experiences, 56 end-of-life experiences, 224 possession, 244 memories suggestive of past lives, 565 mediumship, 44 others). Over the decades, there was an evident increase in the number of articles on all the areas of the field, with the exception of studies on mediumship that showed a decline during the late 20th century and subsequent rise in the early 21st century. Regarding the types of articles found, with the exception of past-life memories and end-of-life experiences (mostly original studies), publications were predominantly review articles. The articles were published in journals with an impact factor similar to other areas of science.
