What is the basic unit of the brain?

• A. Axon
• B. Dendrite
• C. Neuron
• D. Synapse

Answer: (C)

Neurons are the basic functional units of the brain. They are specialized to receive, process, and transmit information through electrical impulses and chemical signals. Each neuron has dendrites that gather inputs, a cell body that integrates those inputs, and an axon that sends signals to other neurons. The synapse is the contact point where communication occurs between neurons. The brain’s computations arise from networks of these neurons firing and communicating, not from individual axons, dendrites, or synapses in isolation. So the neuron is the fundamental unit because it embodies the cell type that both processes information and forms the circuits that underlie all brain activity.
