How does the brain work?
Quick Answer
The brain works through billions of nerve cells that pass electrical and chemical signals, forming the networks behind thought and memory.
The Full Story
The human brain contains an estimated 86 billion neurons, cells that communicate by firing electrical impulses and passing chemical messengers across tiny gaps called synapses. Groups of neurons form vast, interconnected networks that control everything from breathing and movement to memory, emotion, and reasoning. Different regions specialise in different jobs, yet they work together seamlessly. Despite huge advances, the brain remains one of the most complex and least fully understood objects in the known universe.
