Neural oscillation is something that happens inside of our brains. It's like electricity that moves in waves. Our brains are made up of individual brain cells called neurons. When these neurons communicate with each other, they send electric signals to each other that are called impulses. The impulses can group together to form different types of electrical waves. Neural oscillations are when these waves move back and forth in a regular and repeating pattern. It's like waves in the ocean that keep going in the same direction. The waves in our brains help our brains perform tasks like thinking, learning and understanding.
