[Q]: 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.
[A]: Science

[Q]: Implicants of this type are minimal in their number of literals when considering Boolean functions. Finite fields can only have orders of this type. Elements of this type in rings divide some element in an arbitrary factorization and they are equivalent to irreducible elements in a unique factorization domain. The fundamental theorem of arithmetic states that a number may be written as a unique product of numbers of this type. The Sieve of Eratosthenes was an early method for finding these numbers. For 10 points, identify this adjective that, when applied to the natural numbers, describes a number with exactly two divisors.
