Summary Projections and trabeculae consisting of neurons, neuroglial cells, and their processes extend from the rostral aspect of the nucleus lateralis of the rat. The dendrites of these neurons interweave with large packets of incoming myelinated fibers. Electron microscopy shows that synapses occur between these neurons and the afferent axons. Two possible developmental explanations for this arrangement are considered. (1) The cells may have been induced to migrate away from the main mass of the nucleus as a result of the delayed arrival of an important contingent of afferents. Alternatively, (2) these rostral cells may have migrated a longer distance for intrinsic reasons and consequently met their afferents at a location more peripheral to the main nuclear mass. In either case, the projections and trabeculae may reflect the segregation from the main nuclear mass of a certain group of neurons and their afferents having specific topographic or functional attributes.
