This astounding neuroscience rediscovery could be a central piece of the puzzle

Some bold and persistent researchers have rediscovered an unusual bundle of nerve fibres or a “major white-matter fascicle” in the human brain. Nice work! It is now called the vertical occipital fasciculus (VOF). This discovery could be an important new piece in the puzzle in researching and exploring ideas that I’m looking at in this blog, such as the relationship between the many different varieties of synaesthesia and face recognition or face memory and also reading ability. I think this discovery could be highly relevant because the rediscovered structure is a pathway of white matter that connects the occipital lobe at the rear of the brain, where visual processing happens, to other areas of the brain, and there is speculation that information carried by this pathway could play a role in face recognition and reading. I have proposed that synaesthesia might be linked to superiority in face recognition (super-recognition) and superiority in reading, citing myself and close kin as examples. I have also described and written about types of synaesthesia that involve faces or other complex memories of images as the concurrent or the inducer or both. Researchers have found that grapheme-colour synaesthesia is characterized by greater coherence in the white matter network in the brain, and that would presumably include the rediscovered VOF. I have identified the rear of the brain, the right hemisphere of the brain and the fusiform gyrus as the parts of my brain that are most likely be the locations of the events that give rise to my super-recognition and synaesthesia and related interesting goings-on, so this white matter highway at the back of the brain  is very likely involved in these processes.

I’m amazed by the story of how this brain pathway came to be forgotten or discredited by science. Apparently because it was unusual in it’s orientation its very existence conflicted with established thinking at the time, so it became non-existent in the eyes of science. I’m sure that many scientists and neuroscience enthusiasts will be surprised that dogmatic thinking in science can create an important “blind spot” in scientific knowledge, but I’m not one of those people. I’ve seen too much misbehaviour, bias and simple ignorance in neuroscience to believe that the fairy-tale accounts of science as an automatically self-correcting enterprise apply to this corner of the world of science.
