Explanations > How the Brain Works > Understanding the brain
Here is a set of pages on how the brain and nervous system works, in a sequence that may, if you wish, be read like a book.
The big picture
Here's some details on the bigger picture of the brain and other articles and notes.
-
Physiological psychology: The study of brain and behavior.
- The nervous system: The main systems of the brain and body nerves.
- Neural directions: Fancy names used.
Brain cells
Neurons are the major component of the brain and nervous systems.
- Neurons: The main neural cells.
- Neuron internals: The bits inside neurons.
- Glia: Supporting neural cells.
- Schwann cells: provide myelin in peripheral system.
- Blood-brain barrier: Keeping them apart.
- Neural electronics: Transmission down axons.
- Inter-neuron communication: How neurons communicate with one another.
Brain parts
Here are parts of the brain and their main constituents and purpose.
- Brain subdivisions: Major parts.
- Left and right brain: Hemisphere differences.
- Forebrain: The big bit.
- Ventricular system: Fluid-filled central cavities.
- Cerebral cortex: The thinking walnut.
- Limbic system: Central kit of parts.
- Basal ganglia: A few other bits.
- Midbrain: Two central systems.
- Hindbrain: The old bit.
Brain chemistry
There are many chemicals and substances that affect the brain.
