What is the primary function of neurons in the brain?

Neurons are specialized cells in the brain and nervous system whose primary function is to transmit information throughout the body. This is accomplished through electrical signals known as action potentials, which travel along the neuron and result in the release of neurotransmitters at synapses, enabling communication between neurons. Essentially, neurons allow information to be processed and conveyed, facilitating all forms of mental and physical activities, from reflexes to complex cognitive functions.

Transporting oxygen is a task assigned to red blood cells, while connecting synapses refers to the broader network formed by many neurons rather than a primary function of individual neurons. Storing memories is a complex process involving multiple brain regions and mechanisms, including synaptic plasticity, rather than being a direct function of neurons themselves. Thus, the primary and defining role of neurons lies in their ability to transmit information, making the answer both foundational and crucial for understanding brain function and development.
