Recent evidence from our laboratory indicated that certain portions of medial cortex in the rat frontal cortex supported self-stimulation. In an attempt to confirm this finding and to explore the possibility that other regions of frontal cortex support self-stimulation, small fine-wire bipolar electrodes were placed throughout the frontal pole in each of 101 adult albino rats. Two regions of the frontal cortex supported self-stimulation. One region, described by us previously, was located in the medial wall of the telencephalon and is typically labeled pregenual or medial cortex. The other region was the sulcal cortex on the dorsal lip of the rhinal sulcus. This region, to our knowledge, has not previously been implicated as an anatomical region which supports self-stimulation.
