Ex Input:
In studying this structure, Elizabeth Gould showed that dendrite spine density and estradiol levels peaked together. A circuit of structures interconnecting this structure and the cortex was proposed by James Papez, and axon collaterals named for Schaffer innervates neurons in the CA1 portion of this structure. Neurons that respond only when an animal is in a certain region of space, known as place cells, are located in this structure. It consists of two sheets of neurons called Ammon's horn and the dentate gyrus, the first of which sends axons into the fornix. Connected ventrally and laterally to the olfactory cortex, this structure inhibits CRH release. For 10 points, name folded structure of the limbic system that plays a major role in learning and memory.

Ex Input:
Halogen addition to them creates a mixture of a 1-2 and 1-4 addition product. One preparation of them involves butane undergoing thermal dehydration. Another synthesis of the conjugated variety of this chemical group involves elimination of unsaturated alcohols and alkyl halides. They include a number of useful reagents, including ones named for Chan, Dane, Brassard, Rawal, and Danishefsky. In addition to the conjugated variety, they also occur in isolated and cumulated varieties. Conjugation energy guarantees that the conjugated form is the most stable. For ten points, what is this organic functional group whose 1,3 variety are a principal reactant in the Diels-Alder reaction, and which is characterized by a pair of double bonds.

Ex Output:
