| Popis: | Rats with lesions of the lateral septum or the ventral hippocampus are deficient in acquiring conditioned suppression of drinking when a noise is paired with electric shock to the feet, but proficient in acquiring an aversion to drinking a flavor when it is followed by illness. Medial septal lesions produce a similar proficiency, but noise-shock learning is not greatly affected. Amygdala lesions produce deficiencies in both regards while dorsal hippocampal lesions produce little effect upon either paradigm. No lesion yielded animals which were capable of acquiring the noise-shock suppression, but incapable of acquiring the taste-illness aversion; thus, it appears easier to disrupt control of the external environment and spare regulation of the internal environment, than to produce the converse effects. In fact, internal regulation is often facilitated as if destruction of external control removed an inhibitory influence on internal mechanisms. |
