    Notes: Summary In a series of experiments in which the known projections of the septal complex to the hippocampal formation have been transected, we have used both anterograde and retrograde tracing techniques in an attempt to demonstrate a ventral septo-hippocampal pathway. In cases where transections of the fimbria, dorsal fornix and supracallosal stria were complete, injections of the retrograde tracers wheat germ agglutinin-conjugated horseradish peroxidase or Fast blue, resulted in labeled cells in the ipsilateral septal complex, primarily in the nucleus of the diagonal band. The number of cells labeled in these experiments was approximately 5–10% of that seen in experiments in animals with intact dorsal pathways who had received similar injections. The presence of a ventral pathway was confirmed in anterograde labeling experiments in which injections of 3H-amino acids were made into the septal complex. The autoradiogfaphs demonstrated that the projection terminates most heavily in the entorhinal cortex and to a lesser extent in the ventral subicular complex; there may be an additional minor projection to the temporal half of the hippocampus and dentate gyrus. Finally, using double labeling procedures, we were able to demonstrate that at least a portion of the cell population that gives rise to the ventral pathway demonstrates choline acetyltransferase immunoreactivity and is presumably cholinergic.

    Notes: Summary Projections from the acoustic thalamus to the lateral nucleus of the amygdala (AL) have been implicated in the formation of emotional memories. In order to begin elucidating the cellular basis of emotional learning in this pathway, the ultrastructure and synaptic associations of acoustic thalamus efferents terminating in AL were studied using wheat-germ agglutinated horse-radish peroxidase (WGA-HRP) and Phaseolus vulgaris Leucoagglutinin (Pha-L) as ultrastructural anterograde axonal markers. The tracers were injected into those areas of the thalamus (medial division of the medial geniculate body and posterior intralaminar nucleus, MGM/PIN) known both to project to AL and to receive afferents from the inferior colliculus. Terminals labeled with WGA-HRP or Pha-L in AL contained mitochrondria and many small, round clear vesicles and 0–3 large, dense-core vesicles. Most labeled terminals formed asymmetric synapses on unlabeled dendrites; of these the majority were on dendritic spines. These data demonstrate that projections from the acoustic thalamus form synapses in AL and provide the first characterization of the ultrastructure and synaptic associations of sensory afferent projections to the amygdala.
