Circuits in the brain: a model of shape processing in the primary visual cortex

Dr. Charles Legéndy’s Circuits in the Brain: A Model of Shape Processing in the Primary Visual Cortex is published at a time marked by unprecedented advances in experimental brain research which are, however, not matched by similar advances in theoretical insight. For this reason, the timing is ideal for the appearance of Dr. Legéndy’s book, which undertakes to derive certain global features of the brain directly from the neurons. Circuits in the Brain, with its “relational firing” model of shape processing, includes a step-by-step development of a set of multi-neuronal networks for transmitting visual relations, using a strategy believed to be equally applicable to many aspects of brain function other than vision. The book contains a number of testable predictions at the neuronal level, some believed to be accessible to the techniques which have recently become available. INDICE: From the contents Part 1. Concepts of Brain Theory. 1. Lettvin’s challenge. 2. Issues concerning the nature of neuronal response. 3. "Events" inthe brain. 4. Cell assemblies. 5. Surprise, statistical inference, and conceptual notes. 6. A new term: ignitions which "reach" or "don’t reach" a neuron. 7. Confirmation loops, powered by self-ignitions. 8. Communicating "relatedness" through time-linked ignitions. 9. Relational firing: broadcasting a shape through time-linked ignitions.- Part 2. Contour strings and the contour wave. 10. Enter the contour string. 11. Drift of the retinal image. 12. Theory of thesimple cell. 13. Theory of the complex cell. 14. Corner processing: theory ofthe hypercomplex cell.- Part 3. Nodes, links, bridgeheads. 15. Nodes on contour strings. 16. Custom-made unstable networks made to support tracking. 17. Why is the drifting retinal image helpful in perception?
