Principles of Biological Psychology

Everything psychological is simultaneously biological.
: There would always be a biological explanation for our actions and thoughts. Inside our bodies, neurons are working to stimulate physical responses. Beneath our actions and thoughts, there would always be a biological justification.

The nervous system is complexity build from simplicity.
: Our nervous system works in systems, meaning, there are systems, sub-systems, smaller sub-systems, and so on. The smallest sub-system is what we all known as “neurons”. What a single neuron can do is to create an electrical spark, and pass on the message. However, our nervous system is made from billions of neurons, creating a complex nervous system.

The brain is both specialized and integrated.
: There are parts of the brain that are specialized in doing something such as hormone secretions, etc. However, some other parts of the brain need to work together in order to stimulate a behavior/response. So they are both specialized and integrated.

The nervous system is “plastic” especially at early ages of development.
: We are able to shape people’s nervous system at the certain age. The nervous system, including the brain, is very easily developed as you grow up.
