History

Democratic People's Republic of Korea Established

During the Soviet occupation of North Korea, a Korean Communist named Kim Il Sung was selected to lead the new state. Kim had remained loyal to the Soviet Union while in exile during World War II, becoming a Captain in their Red Army. Under Kim's leadership, North Korea established Soviet-style regulation of the economy and fought a war with US-backed South Korea. After Kim Il Sung's death in 1994, his son, Kim Jong Il, took power. Why have the two Koreas technically been at war since 1950?

The Cerebral Cortex

The vertebrate brain's cerebrum is covered by an outer layer, or cortex, that is largely responsible for higher brain functions, including sensation, voluntary muscle movement, thought, reasoning, and memory. It is composed of unmyelinated fibers that—in preserved brains—are grey in color, hence the name “grey matter.” Each region of the cerebral cortex is highly differentiated and sends and receives information specific to its function. What is the main source of cortical stimulation?

Luigi Galvani

Galvani was an Italian physiologist and physician. While experimenting with electricity, Galvani noticed that a frog's leg contracted when it was touched with charged metal. He incorrectly concluded that animal tissue generates electricity. Galvani's research focused attention on electricity in animals, stimulating the study of electrotherapy and electric currents. Today, many terms in electricity are derived from Galvani's name. How did his work influence Mary Shelly's Frankenstein?
