Translation of "sch3" into Icelandic

S.Ch.3 1. In this chapter we followed the path of image processing from the eyeball to the brain. Neurons in the cerebral cortex translate the array of activity signalled by retinal ganglion cells into the beginnings of forms and patterns. The primary visual cortex is organised into thousands of tiny computers, each responsible for determining the orientation, width, colour, and other characteristics of the stripes in one small portion of the visual field. In Chapter 4 we will continue this story by seeing how other parts of the brain combine the outputs from these minicomputers to produce a coherent representation. 2. Perhaps the most important feature of image processing is the remarkable transformation of information from the circular receptive fields of retinal ganglion cells to the elongated receptive fields of the cortex.

3. Cortical neurons are highly selective along a number of dimensions, including stimulus orientation, size, direction of motion, and eye of origin. 4. Neurons with similar preferences are often arranged in columns in the primary visual cortex. 5. Selective adaptation provides a powerful non-invasive tool for learning about stimulus specificity in human vision. 6. The human visual cortex contains pattern analysers that are specific to spatial frequency and orientation.
