The SEPTAL NUCLEI
- - - A look at Figure 13-1 and Figure 13-2 shows that the septal nuclei seem to be a focal point, where many pathways of the Limbic System originate or terminate. This is a remarkable but poorly understood region of the brain. In a classic series of experiments James Olds implanted electodes in the septal region in animals and hooked the wires up to an electrical pulse generator in such a way that the animals could deliver stimuli to their own brains by pressing a pedal in their cage. The animals loved it, pressing the pedal for hours on end; hungry animals preferred the stimulus over food. So, some call this a pleasure center. In any event, you ought to be able to find the nuclei on slides so look at Cu Slide 40.
