Too exciting! Nobel Prize awarded for research on stuff that I’ve been writing about here

Visual recognition of places or scenes, mental navigation, a sense of place and the normal mental memory function that is the basis for the “method of loci” memory technique are some of the interesting psychological subjects that I have written about here, and it appears that my interests very much overlap with the areas of research pioneered by John O’Keefe and May-Britt and Edvard Moser, all winners of the 2014 Nobel Prize for Medicine. This team spent a great part of their careers doing research on rats, and their discoveries include grid cells and “place cells” which are nerve cells in the hippocampus that only activate when the rat is in a specific physical location. I’m not clear whether the grid cells and the place cells are the same thing or not. Read about their fascinating and important research here.

I’m feeling very frustrated right now as I am sure that somewhere in this blog I’ve written a description of an experience that I occasionally have while travelling in a train in unfamiliar lines or at night, in which it appears that two different mental navigational systems in my brain go “out of sync” causing a temporary sense of confusion about where I am. One of these navigational systems is based on visual perception of scenes while the other is based on a body-centred, visceral, embodied, spatial, sense of direction, and the common language “spoken” between these two systems is the visual memory of scenes, (which is of interest in my case because this function is encoded in pretty-much the same part of the brain as face memory, and I’m a super-recognizer). Normally the visual perception of scenes system informs and regularly updates the directional sense system, and the directional system accesses a sequentially-encoded system of visual memories of places and then sends predictions about expected scenery back to the visual system. Sometimes when visual scene recognition operates at the edges of ability and fails to provide input to or misinforms the directional system, the directional system works in an uncertain and speculative way, and at times is confronted with input of visual scenes that do not fit the predictions of expected scenery sent from the scene memory bank. This is the “spin-out” moment. Following this head-spinning moment of confusion is a sense of “Where the f*** are we?”, and my sense of navigation will either be reset from a combination of conscious knowledge of direction combined with visual memories of scenes or fresh comprehensible visual input. This is my interpretation of these types of experiences, which I believe are interesting and can inform us about normal mental navigation. I am very conscious of visual memories of scenes because I experience a number of types of synaesthesia in which these memories are either inducers or concurrents. I believe I am the first person in the world who has taken the time to write and publish full descriptions of these experiences, here at this blog. I have asserted that one of these types of synaesthesia is the same or very similar to the very powerful and ancient method of loci memory technique, which involves activation of a number of parts of the human brain, including the hippocampus.

Aussie Nobel Prize winner mentions citizen scientists on ABC’s Lateline

I very much enjoyed watching Professor Peter Doherty AC FRS, Australian immunologist and Nobel laureate being interviewed on Lateline tonight about cuts to science funding and the CSIRO. Professor Doherty did some very important research involving the MHC proteins, which I believe have also been the focus of researchers interested in the development of the mammalian and human brain.  I particularly liked Professor Doherty’s acknowledgement of the roles of citizen scientists in the science community, but I take issue a bit with his characterization of citizen scientists as generally people who have no training in science. There are plenty of people in the community who have academic achievements of various kinds in science or applied science who do not have paid jobs in science, for whatever reason. This doesn’t mean we aren’t educated or qualified or knowledgeable. Some voluntary roles in the community have more stringent training and screening processes than paid jobs, so the relationship between training and having a real job is also not absolute.
