Interesting facts about the human brain

The human brain has the same general structure as the brains of other mammals, but is larger than any other in relation to body size. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using the encephalization quotient which compensates for body size, the human brain is almost twice as large as the brain of the bottlenose dolphin, and three times as large as the brain of a chimpanzee.

- Scent acts as a powerful memory trigger. The olfactory nerve is located closely to the amygdala — an area of the brain associated with emotional memory — and the hippocampus.

- The hippocampus, a horseshoe-shaped area of the brain, plays an important role in organising and storing information from short-term memory into long-term ones.

- Countless movies and TV shows depict characters suffering from amnesia, losing past memories and identities. However, real-life cases of amnesia are very rare. Also, these depictions are highly inaccurate.

- Neurons develop at the rate of 250,000 per minute during early pregnancy.
