Human brain

If you are not really in the mood for serious intellectual effort, Maldoo (electronic board-games board) is here. Human Cognition in the Human brain. This site contains texts that I wrote about cognitive psychology, by which I mean the investigation of the way thinking (in its widest definition) is done. I started with a model of the way the human... cognition is implemented, and then added texts discussing points that have arisen from various comments I got. If you are not reallin into cognitive psychology, you can try few other bits . The main point that distinguishes my model from other models is that I try to make it plausible neurobiologically. By 'neurobiologically' I mean the characteristics of neurons and their connectivities in the brain. As far as I can see, all the current models of human thinking ignore neurobiology, and more than that, they are neurobiologically implausible. The essential feature that most of these models ignore is the stochastic nature of the low-level connectivity of neurons. See brain symbols for a discussion showing that symbolic systems are implausible because of this reason. This text was first submitted for publication in Apr96. This paper got quite impressive reviews . The stochastic connectivity in the cortex is 'hidden' from the rest of the public by neuroscientists, and here are online examples. A short letter to neuroscientists calling them to advertise the stochastic connectivity of the cortex, which I tried unsuccessfully to publish. New methods, like PET and fMRI, open new avenues in investigation of the brain. However, currently the results are not replicable, and there is a strong tendency to overinterpret the results, and worse, to avoid any discussion of these overinterpretations. I am trying to publish a paper that shows the lack of replicability in PET and fMRI . There is also A general discussion of cognitive brain imaging here, and here is an example of what happens when you try to challenge these overinterpretations. While ignoring neurobiology, cognitive ...Read More
