| Abstract: | Using the method based on HRP retrograde axonal transport organization of projections of substantia nigra, tegmental ventral field and amygdala on pallidum was studied. Neuronal fibres from all dopaminergic portions of substantia nigra and tegmental ventral field were found to project on both structures of dog dorsal pallidum (globus pallidus and entopeduncular nucleus). Ventral pallidum receives projectional axons only from neurons of basal nucleus of amygdala and tegmental ventral field. |
