How Does the Brain Really Work?

The brain works like a big computer. It processes information that it receives from the senses and body, and sends messages back to the body. ... Brain tissue is made up of about 100 billion nerve cells (neurons) and one trillion supporting cells which stabilize the tissue.

How does the brain actually think?

It is estimated that the human brain has close to 100 billion neurons. Neurons release brain chemicals, known as neurotransmitters, which generate these electrical signals in neighboring neurons. The electrical signals propagate like a wave to thousands of neurons, which leads to thought formation.

Is the brain fully understood?

We're never going to be able to fully describe or understand how an individual thinks, or what an individual's memories might be and how those memories contribute to what those individuals are. So individual human brains are entirely unique, and entirely inscrutable, and we're never going to understand that.
