Fig. 1.2. Relative wavelength sensitivities of rods and L, M and S cones. S or 'blue' cones actually absorb maximally in the green-yellow region
Fig. 1.4. Dorsal view of the visual pathways. Retinal visual signals have their first synapse in the dorsal lateral geniculate nucleus (LGN) of the hypothalamus and then travel, via the optic radiations to cortical visual areas in the occipital lobe
Fig. 1.5. The centre-surround receptive fields of the retinal ganglion cells in the optic nerve are sensitive to local light changes (contrast) and thus constitute the first stage of edge detection which forms the basis for the recognition of objects in th
