Development of ocularity domains and growth behaviour of axon terminals.


Ontogenetic development of ocularity domains--stripes, patches and layers in cortex, colliculus superior and lateral geniculate nucleus--is the result of organization that may either be intrinsic to the postsynaptic structure or induced to it by the afferents. A specific type of axonal growth behaviour that was recently proposed as a basis for ontogenetic development of retinotopy is sufficient to account also for ocularity domains. No intrinsic organization in the postsynaptic structure is required. The latter merely serves as a propagating medium for markers carried by the presynaptic terminals. Computer simulations demonstrate the mechanism to be complete and consistent.
