“Everything psychological is simultaneously biological.”
The brain like a CPU controls everything in the human body on how we feel, see, taste, smell, and hear things. For example, when a baby touches a heated steel pot, the sensory neurons in his body would send the alerting message to the spinal cord then sends to the brain. Once the baby feels the unbearable temperature in contact with his skin, he will automatically draw back, and starts crying (emotion expressed). Hence, this gives support that everything psychological and biological are interrelated.

“The nervous system is complexity build from simplicity.”
Neurons are the fundamental building block of the nervous system. Yet, these great amounts of cells are essential because among the neural network, neurons either receive or send message from their neighbors, and these messages (neurotransmitters) signals our body to respond.

“The brain is both specialized and integrated.”
In other words, our brain is divided into two hemispheres, the left side and the right side. Either side has a specialized function, for instance, in the case of tactile and auditory pathway, if a person touches and hears something with their left ear/arm, the message will be send to his right hemisphere. Nonetheless, both hemispheres are at work in the case of visual pathway because each of the retinas is connected to both hemispheres.

“The nervous system is “plastic” especially at early ages of development.”
During the phase of infancy, growth and development are at work. Especially, in babies’ brains the hundred and thousands of neurons expand and connect with their neighbors forming a neural network from experiences, caused by the readily adaptation of the brain. In fact, it can be easily manipulated, hence, the so-called “plastic".
