Neurogenesis is the generation of new neurons in the human neural network.
It can enhance reading comprehension through the creation of new norepinephrine related neurons and enhance motivation through the creation of new dopamine related neurons. These neurons communicate through electrical signals flowing through synaptic electric gaps bridged by neurotransmitters like norepinephrine, dopamine, and adrenaline.
However, the quantity of neurons is not the only important factor in determining the speed and quality of internal communication in the human body; neurons' quality for performing their proper function like release and reuptake of neurotransmitters is also a factor, especially in disorders like attention deficit hyperactive disorder (ADHD) and schizophrenia.
Most natural neurogenesis occurs in children and most natural neurodegeneration occurs in the elderly, but drug induced neurogenesis and drug induced neurodegeneration can be garnered at any age.
