7supporting details on the human brian

The brain is one of the largest and most complex organs in the human body.

It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses.

• The cortex is the outermost layer of brain cells. Thinking and voluntary movements begin in the cortex.

• The brain stem is between the spinal cord and the rest of the brain. Basic functions like breathing and sleep are controlled here.

The human brain is the command center for the human nervous system.

It receives signals from the body's sensory organs and outputs information to the muscles.

The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains.

Is there more to this?
