Oscillatory neural networks are computer models that try to copy the way that brain cells (called neurons) talk to each other. Neurons send signals back and forth using electrical charges (called oscillations), and these signals help the brain do things like think and remember. In an oscillatory neural network, computers are made to act like a network of neurons. They are programmed to "talk" to each other by sending these electrical charges, just like real neurons in your brain. They do this so they can learn complex tasks. So, an oscillatory neural network is like a computer brain that can learn and do things!
