I find this most interesting for a number of reasons. Firstly, the discovery showing that the human brain has functional lymphatic vessels connecting the brain with the immune system adds to a growing collection of evidence that the immune system plays important roles within the brain, which is an apparent partial violation of the long-held concept of the “blood-brain barrier” (as was described in a dated and inadequate chapter by Dr Karl in his 2013 pop science book Game of Knowns). In 2012 I was apparently the first person in the world, at this blog, to publish the ideas that high or low levels of the “component” immune chemicals at various points in development could be the cause of conditions of the brain such as developmental synaesthesia and Benson’s syndrome or PCA. My ideas were inspired by the very exciting research in areas such as microglia, complement, synaptic pruning and MHC1 molecules.

Another reason why this new discovery linking the central nervous system with the lymphatic and immune systems by researchers from the University of Virginia is so exciting is the fact that it is an unexpected discovery, as one might have thought that human anatomy would have already been thoroughly researched and discovered through the history of medical science to date, but then again, surprising new discoveries in human anatomy have not been unknown in recent years, with discoveries of new features in the human eye, knee and clitoris, the rediscovery last year of a major white matter tract (the vertical occipital fasciculus) at the rear of the brain that could play a central role in skills such as reading, and a new shape of neuron discovered in mouse brains. These new discoveries are exciting and also rather unsettling; exciting because it appears that important new discoveries in human neuroscience and anatomy are still possible, and unsettling because genuinely surprising new discoveries in science seem to indicate that science is not a steady accumulation of knowledge and a path of upward progress, as many believe. This may or may not be surprising to you, depending on which theory in the philosophy of science you favour. I think the discoveries of the VOF and the collection of discoveries about the roles and anatomy of the immune system in the human brain could be interpreted as evidence showing how incorrect ideas in science can become widely-accepted and widely-taught and could also have delayed the progress of new discoveries in neuroscience. How much further might we have come by now in our understanding of the human brain and mind if not for the popularity of the idea that the human brain is quarantined from the immune system? Which other influential ideas about the human brain are holding us back from a clearer understanding of the brain’s workings and diseases?

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.
