For more than 30 years, the visual cortex has been the source of new theories and ideas about how the brain processes information. The visual cortex is easily accessible through a variety of recording and imagining techniques and allows mapping of high level behavior relatively directly to neural mechanisms. Understanding the computations in the visual cortex is therefore an important step toward a general theory of computational brain theory.... channel (or bypass the LGN entirely) lead to the same results as simulations that include both the ON and OFF channels of the LGN explicitly. ... This sheet was mapped directly to the cortex like the LGN sheets (Figure A.1), and sized like the LGN sheets (R = L). ... to 6wdor2Io/r2I for historical reasons, and the afferent learning rate Ip A was increased to 0.003 after iteration 10, 000; all other parametersanbsp;...
