How does the brain create memories?
assistant
The brain is made up of billions of cells called neurons. Neurons are connected to each other by synapses, which allow them to communicate with each other. When a neuron fires, it sends a signal down its axon, and when another neuron receives that signal, it can fire as well. This process is called synaptic plasticity. When a memory is formed, the connections between neurons strengthen, allowing the memory to be stored more easily.
