Question

What is the structural and functional unit of brain and spinal cord?

Answer 1

The basic functional unit in the brain is defined by how neurons communicate, and consists of two neurons and their interconnecting dendritic-synaptic-dendritic field. Since a functional unit is composed of two neurons, it requires two structural units to form a functional unit.

Neurons are the structural and functional units of the nervous system or spinal chord as well. They transmit electrical signals, called nerve impulses. Glial cells provide support for neurons.
