Abstract
In the primary visual cortex of monkeys and cats, regions relatively strongly stained by cytochrome oxidase (CO) appear to be patches arranged over the cortical surface, which are called CO blobs. In macaques or galagos, CO blobs have been found along the middle of ocular dominance (OD) bands [1], which indicates that CO blobs and OD columns do not develop independently, while the structural relationship between CO blobs and OD columns in cats [2] or squirrel monkeys [3] is not clear. Such observation raises a question of what mechanism is commonly underlying the formation of CO blobs and that of OD columns. Here, we propose a self-organization model based on the Hebbian learning rule that accounts for the coordinated development of CO blobs and OD maps observed in monkeys and cats.
