The olfactory tracts in the cod (Gadus morhua L.) consist of four bundlets. Three were cut symmetrically in both sides leaving only one of the four bundlets intact. Weak electrical pulses given to the uncut bundlets elicited, for each, a different behavior pattern in free-swimming cod. The results support a spatial basis for olfactory discrimination and open new experimental possibilities linking the neuroanatomical substrate and fish behavior.
