Brain areas involved in the neuroanatomy of memory such as the hippocampus, the amygdala, the striatum, or the mammillary bodies are thought to be involved in specific types of memory. For example, the hippocampus is believed to be involved in spatial learning and declarative learning, while the amygdala is thought to be involved in emotional memory. Damage to certain areas in patients and animal models and subsequent memory deficits is a primary source of information. However, rather than implicating a specific area, it could be that damage to adjacent areas, or to a pathway traveling through the area is actually responsible for the observed deficit. Further, it is not sufficient to describe memory, and its counterpart, learning, as solely dependent on specific brain regions. Learning and memory are attributed to changes in neuronal synapses, thought to be mediated by long-term potentiation and long-term depression.

What changes can be linked to learning and memory?
Answer: neuronal synapses,

On the night of December 25, 1991, at 7:32 p.m. Moscow time, after Gorbachev left the Kremlin, the Soviet flag was lowered for the last time, and the Russian tricolor was raised in its place, symbolically marking the end of the Soviet Union. The next day, December 26, 1991, the Council of Republics, the upper chamber of the Union's Supreme Soviet, issued a formal Declaration recognizing that the Soviet Union had ceased to exist as a state and subject of international law, and voted both itself and the Soviet Union out of existence (the other chamber of the Supreme Soviet, the Council of the Union, had been unable to work since December 12, 1991, when the recall of the Russian deputies left it without a quorum). The following day Yeltsin moved into Gorbachev's former office, though the Russian authorities had taken over the suite two days earlier. By December 31, 1991, the few remaining Soviet institutions that had not been taken over by Russia ceased operation, and individual republics assumed the central government's role.

What went down after Gorbachev departed from the Kremlin?
Answer:
Soviet flag
