Abstract: | This paper describes a mechanism for (1) bottle-neck optic nerve conduction and (2) the recognition of visual spatial forms.
(1) In this mechanism thew retinal receptor neurons are in one-one causal relation to a setD ofw central neurons, the connecting optic nerve containing less thanw fibers. (2) Also a set ϕ of μ spatial forms (herein defined) is in the one-one causal relation to a setF of μ central neurons so that iff
i
(any given number ofF) fires, then the correspondingφ
i
has occurred in the retinal image. Onlyφ
i
can firef
l
, butf
l
may fire for any position, size or orientation ofφ
i
on the retina, with the restriction thatφ
i
not be smaller than a minimum size which is a function of retinal position. Neuron economy is considered throughout. |
