Fig. 6. x-y plots of receptive field position of dorsal octavolateral nucleus (DON) units vs cell location within the DON. The y-axis represents the normalized receptive field position. Zero is at the tip of the rostrum and 10 cm is the position of the nose opening just in front of the eye. Receptive field values for different sized fish were normalized and projected onto a standard fish with a tip-to-nose distance of 10 cm. (A) The x-axis represents the position of the cell along the rostro-caudal axis as % of total DON length. Zero represents the rostral end of the DON, 100 represents the caudal end of the DON. (B) The x-axis gives the cell position along the medio-lateral extent of the DON in percent. Zero means the medial border of the DON, 100 its lateral edge. Each symbol represents a DON unit whose receptive field position was measured. There is no correlation between the location of a cell in the DON and its receptive field along the rostro-caudal axis of the rostrum.
