The septal nuclei are still there. In rats, yes, stimulation to that area was preferred over food or water. In humans its function is not well understood although it is classified as part of the limbic system. Given the likely importance of networks of areas, it would be simplistic to call it the pleasure center in humans; what it's connected to is part of what makes it important. Its projections include hippocampus (for episodic memory, among perhaps other functions) which also project to the septal nuclei, and to brain stem and a variety of subcortical areas such as the habenula.
