Can you explain how the brain works?

The brain is made up of billions of cells called neurons. Neurons are connected to each other by synapses, which allow them to pass electrical signals back and forth between one another. When a neuron receives a signal from another neuron, it will either pass that signal on to its own dendrites or it will not. If a neuron passes on the signal, it will then release chemicals known as neurotransmitters, which can travel across the synapse and affect the receiving neuron. This process is known as synaptic transmission.
