Quinine is extracted from the bark of the Cinchona tree, native to South America. It has been historically used to treat malaria and is still used today in certain medications like tonic water.

The brain is the fattiest organ in the human body, consisting of approximately 60% fat. This high fat content is essential for proper brain function, as fats provide insulation, protection, and are crucial components of cell membranes.

The brain consumes about 20% of the body's oxygen supply despite representing only about 2% of body weight. This high oxygen demand reflects the brain's intense metabolic activity as it constantly processes information.

Sleep deprivation specifically impairs the brain's ability to form new memories, as memory consolidation primarily occurs during sleep. The hippocampus, crucial for memory formation, is particularly affected by lack of sleep, making it harder to create and retain new memories.

Neuroscience is the scientific study of the brain and nervous system, including their structure, function, and disorders. Psychology focuses on behavior and mental processes, while Psychiatry deals with mental health treatment.

The human brain contains approximately 100 billion neurons, though estimates range from 86-100 billion. This massive network of neurons forms the basis for all brain functions, from basic survival reflexes to complex cognitive processes.

Crickets can accurately indicate air temperature through their chirping rate - cricket chirps increase predictably with temperature. This relationship is so reliable that you can calculate temperature in Fahrenheit by counting chirps in 14 seconds and adding 40.
