Title: The projection of the ventral tegmental area to the olfactory tubercle in rats
Abstract: The projection of the ventral tegmental area (VTA) to the olfactory tubercle(OT)was studied with in 20 rats with retrograde axonal transport of hoseradish peroxidase(HRP). The labelled cells appeared only in the ipslateral VTA-A10 area, not in the controlateral. The labelled cells were distributed mainly in the lateral of the VTA and gradually decreased from the lateral to the medial. The labelled cells in the VTA were destributed mostly in the medial 1/3 part, less in the caudal 1/3 part and the least in the rostral 1/3 part. The labelled cells were large triangle and multipolar in shape. The results showed that some fibers originating from the VTA projected to the OT. The significance of study in the limbic system of the midbrain is discussed.
