I hope all Canadians me included have a wonderful Canada Day. All Canada day events will be online this year because of the Covid-19 pandemic. Which does suck but nothing anyone can do about that. In other news I have just come across another article on the split brain experiments where they continue to show scientific evidence of one locus of consciousness. That when you split the brain you don't have two consciousness but one unified consciousness which is compatible with the filter/receiver analogy of consciousness/mind/brain.

New study provides strong evidence that their isn't two separate streams of consciousness
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.

Dr. Yair Pinto talks more about the evidence showing that when you split the brain you still get one consciousness.

The Unity of Consciousness and the Split-Brain Syndrome
An excellent paper on why split-brain cases don't show to separate streams of consciousness. http://www.philosophy.ox.ac.uk/__data/assets/pdf_file/0003/2757/split-brain_web.pdf. I talked about split brain patient cases before presenting reasons why it doesn't show two separate streams of consciousness well there is more reasons as well.
Split–brain cases do not show the results we would expect if two fully independent, separate streams of consciousness were being generated by callosotomy; subjects can for instance continue to operate both halves of their bodies in unity and perform sometimes highly complex tasks. The evidence, therefore is more compatible with phenomenal unity without joint access (thus, the side of the brain responsible for speech cannot access the contents of that which is seen by the right side of the brain, even though both are contained within a single stream of subjective consciousness). This conclusion is also more parsimonious; and since the two–separate–streams hypothesis is (unlike dualism) an empirical one (instead of metaphysical), considerations of parsimony apply. Therefore, split–brain cases pose no serious difficulty to phenomenal unity, and thus in turn pose no serious difficulty towards dualism.
See also several other papers from Tim Bayne, including an important one with David Chalmers titled ‘What is the Unity of Consciousness?’ as well as from Torin Alter.
Incidentally, subjects born without a corpus callosum altogether, as well as those with agenesis of the corpus callosum, do not experience even the relatively mild symptoms which callosotomy patients do.
What we have here is one subject with a fragmented brain, not the sudden appearance of two ‘persons’ in one skull as some argue. Peter Ellis’ paper, ‘The Decider System Model: A Defense of the Cartesian Theatre’ is also of important relevance both to those interested in criticism of Dennett’s theories as well as the import of callosotomy experiments to philosophy of mind.
