Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuronâanother cell. Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.
Synapses are tiny gaps between neurons, where messages move from one neuron to another as chemical or electrical signals. The brain begins as a small group of cells in the outer layer of a developing embryo. As the cells grow and differentiate, neurons travel from a central birthplace to their final destination. Chemical signals from other cells guide neurons in forming various brain structures. Neighboring neurons make connections with each other and with distant nerve cells (via axons) to form brain circuits. These circuits control specific body functions such as sleep and speech.
