The Computational Theory of Mind is not that the mind does some form of computation in the wide sense of computation. Rather, look at the examples for the CToM given in the Wikipedia article; people like Fodor, Pinker, Marr. Their view is very much the opposite to the Connectionist position of West Coast scientists like Rumelhart, Elman and McClelland. Both ...

I think that your intuition about the lower "energy ratio" of spurious states explaining their greater susceptibility to unlearning might be correct. In a Hopfield Network spurious states are activity patterns that have not been explicitly embedded in the synaptic matrix, but are nonetheless stable. They are in other words "unwanted" attractor states that, ...

Evolution does not help Minsky's theory of a resourceful mind. Although he tries to frame his discussion in loose evolutionary terms in the Emotion Machine and the book it is based on: Society of Mind (here is a good review/summary). As you noted during your reading: Minsky backs himself up by saying "evolution did so", but hasn't provided tests or ...

Research exists on craniopagus twins, maybe most notably Tatiana and Krista, who seem to share sensory input somewhat. I doubt that connective mechanisms such as this abnormal case would suffice to permit "compound cognition" in ways that would enhance cognitive ability similarly to your point about hominid evolution. Your relatively simple proposal for a ...

I wonder if any of the work using Act-R would be relevant. See these Act-R publications with accompanying PDFs on visual search spatial reasoning and navigation (apologies if they're not relevant, this is outside my comfort zone)

Mario Liotti and Don M. Tucker (Brain Asymmetry, MIT, 1996) attempt to explain that the 'corticolimbic architecture is not left/right, but dorsal/ventral". In their opinion, the reason for hemispheric asymmetries can be found in the asymmetries of the dorsal and ventral systems. They proposed that emotional behavior could be interpreted by analyzing the ...

Henderson summarizes very well a number of approaches on human gaze control during real-world scenes and tasks. http://cvcl.mit.edu/iap05/henderson_03.pdf In a nutshell, our visual system combines knowledge about the task (e.g. color of the search target) and external audio/visual stimuli (saliency) to control our gaze inside a scene. Quite insightful about ...

If you are looking for a 'brain model of visual navigation', you just have to google it! You will find a whole Ph.D. thesis that exactly covers all what you are asking for: Learning Objects Places and Relation in a Brain Model of Visual Navigation. http://books.google.com/books/about/Learning_Objects_Places_and_Relations_in.html?id=yJo2twAACAAJ That ...

Consider that elimination of such a phenomena is not ideal. It's been proposed that actual neuronal networks exist under the tension of synchronous decoupling. http://www.sciencedirect.com/science/article/pii/S0896627308001281 To answer your question though, you probably should consider that reciprocal connections might not be between two individual ...

I'm not sure I fully understand your design; perhaps you can clarify what you want your network to learn, why TD-learning "isn't cutting it", and what you mean by 'reinforcement' and 'prediction' learning. In particular, TD-learning is a reinforcement learning model, and it does reward based on predicted (and not just observed) outcomes. However, you seem ...

You may be interested in the FARS model from Fagg and Arbib (1999) that describes the interaction of the two visual streams in the primate brain during object grasping. The article What Puts the How in Where? Tool Use and the Divided Visual Streams Hypothesis (2007) makes use of the dorsal/ventral streams to explain our ability to use complex tool. As Frey ...

Nick Stauner’s reply has some nice discussion about concrete existing work; we also discussed some more speculative possibilities in (Sotala & Valpola 2012), considering the possibility of merging together the minds of two distinct people so that they could share thoughts and skills. In particular, we considered the possibility of “exocortices”, neural ...

Very detailed estimates for almost all of your points, for cat, can be found in Binzegger, T., Douglas, R. J., & Martin, K. A. C. (2004). A quantitative map of the circuit of cat primary cortex. Journal of Neuroscience, 24(39), 8441-8453.

For what it's worth, I did a lot of research and did not find a solution. So I created my own using HTML, jQuery and a canvas. It's not pretty, but it does not require a lot of work because the functionality is simple: When you click on a node, display its edges and the associated weights.
