Abstract
Intracranial self-stimulation (ICSS) of the medial prefrontal cortex (MFC) was not affected by lesions of the medial forebrain bundle, the nucleus accumbens or medialis dorsalis. However, bilateral, parasagittal knife cuts that transected fibers interconnecting the medial and sulcal cortices eliminated ICSS from the MFC with no apparent recovery over a 21 day test period. Similar knife cuts produced only transient effects on lateral hypothalamic ICSS. These data suggest that the neural substrates of frontal cortex ICSS are very different than those that subserve ICSS along the medial forebrain bundle.
