They also seem to project into the limbic system ones current status in relation to both surroundings and thoughts. On the basis of this information, the amygdala is believed to make the persons behavioral response appropriate for each occasion. Function of the Limbic Cortex The most poorly understood portion of the limbic system is the ring of cerebral cortex called the limbic cortex that surrounds the subcortical limbic structures. This cortex functions as a transitional zone through which signals are transmitted from the remainder of the brain cortex into the limbic system and also in the opposite direction. Therefore, the limbic cortex in effect functions as a cerebral association area for control of behavior. Stimulation of the different regions of the limbic cortex has failed to give any real idea of their functions. However, as is true of so many other portions of the limbic system, essentially all behavioral patterns can be elicited by stimulation of specific portions of the limbic cortex. Likewise, ablation of some limbic cortical areas can cause persistent changes in an animals behavior, as follows. Ablation of the Anterior Temporal Cortex. When the anterior temporal cortex is ablated bilaterally, the amygdalas are almost invariably damaged as well. This was discussed earlier in this chapter; it was pointed out that the KluverBucy syndrome occurs. The animal especially develops consummatory behavior: it investigates any and all objects, has intense sex drives toward inappropriate animals or even inanimate objects, and loses all fearand thus develops tameness as well.
