| Abstract: | The sympathetic-related regions of the cerebral cortex were identified in rats after pseudorabies virus injections were made in functionally different targets: adrenal gland, stellate ganglion which regulates the heart, or celiac ganglion which innervates the gastrointestinal tract. Extensive transneuronal labeling was found in limbic system areas: (1) extended amygdaloid complex, (2) lateral septum, and (3) infralimbic, insular, and ventromedial temporal cortical regions (viz., ectorhinal CORTEX=Brodmann’s area 36, perirhinal CORTEX=area 35, lateral ENTORHINAL=area 28, and ventral temporal association CORTEX=Te3 region). Deep temporal lobe structures were prominently labeled, including the amygdalopiriform and amygdalohippocampal transition areas, ventral hippocampus and ventral subiculum. The cortical circuits mediating emotional–autonomic changes (i.e., mind–body control) are discussed. |
