Kant (1781) to Hassabis (2007)
Of late, Md Ismail Sojal has been one of the most prolific, coherent, Facebook content curators, on topics related to artificial intelligence. Today he posted a brief summary of Demis Hassabis' career, which caught my attention. I took particular interest in learning that Hassabis published important papers on the hippocampus, from 2007 onwards, in an area of my research : delineating the software topology of human intelligence. Given how old the paper is, I've probably been influenced by it in ways immemorial. Its findings align very well with my own practical study of how to quantify my conscious experience on moment to moment basis, something I've been studying since around 2003.
In short, the hippocampus ( whose shape reminds me of the clit ), is a part of the brain, which appears to enable what is broadly called "apperception" in Kant's Critique of Pure Reason, Edition A, published in 1781. The hippocampus is structurally significant in data pipelines, because it mediates both the sensory-spatio modelling of ...
- live data, before that data can be sent to long term memory, and
- recalled data, from long term memory
- Live sensory information is passed from the sensory nervous system (SNS) to the hippocampus, from regions of the brain which evolved earlier, e.g. thalamus > neocortex > hippocampus.
- The types of long term memory affected by the hippocampus include "explicit memory" which refers to abstract verbal concepts, and non-motor sensory data bound into gestalten by such concepts ( such as faces ), but it excludes "implicit memory" which refers to the limbic association cortex which learns processes of motor neural system (MNS), such as riding a bike.
- In another vein, the evolutionary history of the hippocampus deserves some reading also, if you're into developmental cognitive science. It turns out that the hippocampus plays a role in the biological phyla of chordates ( including animals, birds, reptiles, amphibians, and fish, among others ), which is played by differently evolved anatomical structures in other phylla of the kingdom animalia.
- In humans, while the hippocampus integrates short-term sensory data into multi-modal spatio-temporal models, longer-term memories are stored in unimodal cortices of the neocortex. These unimodal cortices are also linked to association cortices, which semantically relate various sensory information together. At this junction I must admit it's still not entirely clear to me how much of what we call "conscious experience" can be said to be associated with the hippocampus versus the association cortices. I'll have to continue this study later, though it is not a priority for me this year.
- The thalamocortical and basal ganglia circuits form three parallel, segregated loops, that are worthy of study :
- Thalamostriatal Pipeline ( input )
- Basal Ganglia Processing ( filter )
- Pallidothalamocortical Pipeline ( output )
- The thalamus and superior colliculus are involved in the salient network ( see "triple network model" ), and their key pathways are
- Tectopulvinar Pathway ( feedforward )
- Thalamotectal Pathway ( feedback )
- Thalamic Reticular Network ( modulatory )
- The hippocampus and cerebellum participate in a bi-directional non-motor network, which should also be read deeply.
