Central Nervous System—Internal Organization
Lecture no. 3 from the course: Understanding the Brain
Taught by Professor Jeanette Norden | 31 min | Categories: The Great Courses Plus Online Science Course
We examine how the central nervous system is organized internally, starting with the basic unit: the nerve cell or neuron. The brain and spinal cord are made up of concentrations of neuronal cell bodies called nuclei (gray matter) and bundles of axons coursing between them (white matter).
