It looks like the evidence that materialist's have been touting as powerful evidence against substance dualism. Which it would be if true. That is if there is two separate consciousnesses when you split the Corpus Callousum. However a new study has now provided strong evidence that clearly shows that two separate consciousness is very unlikely. It is welcome news, for Substance Dualist's such as myself who strongly support this view. This particular evidence for two consciousnesses in a brain was used in a new book called the Myth of an Afterlife well it looks like now that interpretation of the evidence is wrong. There is no consciousness split when you split the brain.
This experiment is expected to be repeated several more times says the researcher Yair Pinto.
Here is the study here.
