This study aims to discover neural pathways stimulated by reproductive pheromones eliciting an attractive locomotor response in sea lampreys. Distinct glomerular territories in the olfactory bulb of ovulated female lampreys were injected with biocytin. Dorsoanterior injections revealed labeling in integrative areas (dorsal, medial, and lateral pallia, habenula, thalamus, hypothalamus) and a locomotor control area (striatum). Medial injections labeled the medial pallium, the thalamus and the striatum. Projections to the hypothalamus and the lateral pallium from the dorsoanterior region of the olfactory bulb, that were absent from medial injections, infer functional difference between these two regions. Lateral injections labeled the striatum, suggesting the lateral olfactory bulb is strongly associated with locomotion. The results demonstrate an anatomical difference in the neural connections of distinct regions of the olfactory bulb.Dept. of Biological Sciences.
