Principles of Biological Psychology

"Everything psychological is simultaneously biological."

This statement is saying that our action or emotion will affect our body. Example is when you are angry at someone the neuron will fire and the message will be sent along the axon terminal.

“The nervous system is complexity build from simplicity”

Nervous system is complexity build from simplicity because there is many parts in the nervous system but it is build up with many simple cell such as neurons. Even though neuron can only do two things but the process of it is very complex. Because when the neuron fires the positive charge into the axon, the charge will go through each door of the axon to axon terminal.

“The brain is both specialized and integrated”

The brain of human are made up with two sides. Each side is good at different areas. And they could also communicate with each other because when they receive information that they are not good at it will send it to the other side.

“The nervous system is “plastic” especially at early ages of development”

The higher your ages are the lower your neurotransmitters are. This is because when we grew up we seem to learn more and choose more. One example is language. When we are baby we speak in every sound but when we grew up we seems to speak only the languages we choose to speak.
