Synaptic transmission is the process by which neurons in our brain communicate with each other. It happens when electrical signals, known as action potentials, travel down a neuron and reach its end, called the terminal. At the terminal, the electrical signal is converted into a chemical signal called a neurotransmitter. This chemical signal crosses a tiny gap called the synapse and binds to receptors on another neuron, transmitting the message from one neuron to the next. This allows the brain to send and receive information, enabling various functions and behaviors.
