Neurobiology is a branch of biology that studies the function and structure of the nervous system.
The human brain has around 100 billion nerve cells called neurons.
Nerve signals can run at speeds of up to 120 meters per second.
During sleep, the human brain is still active and performs various functions such as consolidation of memory and information processing.
Exercise can stimulate the growth of new neurons in the human brain.
Serotonin, dopamine, and noradrenaline are examples of neurotransmitters that affect human mood and behavior.
The central nervous system consists of the brain and spinal cord, while the peripheral nervous system consists of nerve cells that are outside the brain and spinal cord.
The human brain can process information in less than 1/10 seconds.
There are glia cells in the brain that function to provide support and protection to neurons.
In stress conditions, the hormone cortisol is produced by the adrenal glands and can affect the function of the human brain.
