The dendritic architecture of the medial terminal nucleus of the @entity1781 in the XXXX , @entity95 , and cat.

The neurons of the medial terminal nucleus (MTN) of the @entity1781 ( @entity1781 ) have been studied in the @entity35 , @entity95 and cat in Golgi-Cox and Golgi-Kopsch impregnated brain sections. The present anatomical findings permit a division of the MTN of these species into dorsal and ventral components (MTNd, MTNv), in agreement with other investigations. The MTNd contains @entity162 neurons with cell bodies that measure in the range of 25-50 microns. These neurons have 2 to 4 primary dendrites which, along with their smaller dendritic branches, are oriented in the plane of the long axis of the MTN (i.e. from ventromedial to dorsolateral). These @entity162 represent 70-80% of the neurons of the MTNd as seen in the Golgi impregnated sections. The remaining 20-30% of the MTNd neurons are nearly all multipolar in shape with somata measuring in the range of 15-25 microns. An occasional multipolar neuron is larger, has a soma that measures around 30-60 microns and has dendrites which extend outward from the cell body to cover large areas of the MTNd. There was considerable extension of the dendrites of MTNd neurons into the MTNv; however, the dendrites of MTNd neurons were not observed extending into the adjacent substantia nigra (SN) or ventral tegmental area (VTA) of Tsai (1925). Conversely, the dendrites of neurons in the neighboring SN and VTA course along the borders of the MTN but only occasionally extend into the MTN.(ABSTRACT TRUNCATED AT 250 WORDS)
