Test your knowledge of the human brain! (Image credit: Science Photo Library/Getty Images)
Here's the human brain: Often compared to a computer, it's the most complex organ in the body, operating on electrical and chemical signals. These signals are transmitted through wires, nodes, and networks to process and store information.
Through these activities, the brain controls our unconscious physical functions, such as appetite and alertness, as well as “higher-order” cognitive abilities, such as problem solving, idea generation, and future planning. The brain has innate plasticity, meaning that it actively responds to new information and actually rewires itself to adapt to new memories and interpretations of the world around it.
Scientists are still exploring the inner workings of the brain, but over the past decades they have learned a lot about how the organ functions. Take the quiz below to test your knowledge of the human brain and its many unique characteristics.
