When a neuron receives signals from other neurons, it generates an electrical charge that travels down the length of its axon and releases neurotransmitter chemicals across a tiny gap, called a synapse. Neurons are constantly in touch with neighboring brain cells. The function and survival of neurons depend on several key biological processes:
Most neurons have three basic parts: a cell body, multiple dendrites, and an axon. Alzheimer’s disease disrupts this communication among neurons, resulting in loss of function and cell death.
They send messages between different parts of the brain, and from the brain to the muscles and organs of the body. The healthy human brain contains tens of billions of neurons-specialized cells that process and transmit information via electrical and chemical signals.
