Fig. 1 Optimal stimuli of neurons in the visual cortex (top 4 rows) and retina and LGN (bottom 2 rows). In the retina and LGN, cells are selective for only the sign of the stimulus, whether it is a dark or a light spot. In the cortex cells are selective for lines or edges. Individual cells are also selective for the width and orientation of their preferred stimulus type. Current Biology 2001 11, R635-R637DOI: (10.1016/S0960-9822(01)00379-7)

Fig. 2 Organisation of inputs to lateral geniculate nucleus neurons. NOT, nucleus of the optic tract; BF, basal forebrain; BS, brainstem; RET, retina; PGN, perigeniculate nucleus; LGN, lateral geniculate nucleus. Redrawn from Figure 4 of Sherman and Guillery (1996).

Fig. 3 Colour coding responses in the LGN. There are two classes of cells, based on the colour directions to which they respond best. (a,b) Cells in the P layers are excited by green and inhibited by red or vice versa. (c,d) Cells in the layers are excited by blue and inhibited by yellow or vice versa.
