WHAT IS YOUR LIMBIC SYSTEM?
AND WHY IS IT SO IMPORTANT?
The purpose of your limbic system is to produce all of the motivational energy and emotional feelings that both your brain and mind need to survive and thrive in a complicated and potentially dangerous environment.
To do so, your limbic system assists in the preservation of the memories of the most salient experiences and most consequential decisions that saved your life or that have worked well for you in the past. It consists of eight major structures, which provide more than eight major functions. They are directly involved in your survival activities. And they are involved in all of your other thoughts and feelings, no matter what their associations and content.
In addition, neurotransmitters cause dozens of hormones to flow through your circulation system (blood veins and vessels), or send biochemical current flowing through your brain and nervous system which is known as your connectome, It consists of all the biochemical neuronal signaling pathways in your brain and nervous system.
These two communication systems --- your blood flow and biochemical current --- cause the many feelings that you experience when they are activated by your healthy brain.
In addition, since your hippocampus, which is a key component of your limbic system, has the triggers for several types of declarative long-term memory resources, its healthy functioning is essential for your perception of having a unique persistent authentic self.
You have special semantic memory, episodic memory, autobiographic memory, and procedural memory (muscle memory), modules in your brain that all have "triggers" in the hippocampus part of your limbic system.
The location of your hippocampus is at the bottom of your limbic system in the most protected part of your three pounds of brain tissue. The reason for this location is that your memory systems are the source of your self-identity.
Therefore, your hippocampus must be protected and kept as safe as possible throughout your life.
Along with brain concussions from accidents and contact sports, dementias (especially Alzheimer's disease) are the most predictable enemies of your self-identity as you plan for the future. The latest brain research has demonstrated that your brain's prefrontal cortex, is the source of your ability to plan and decide.
However, the executive control function of the prefrontal cortex does not develop fully until between the mid-20s and mid-30s. Nevertheless, you can be an active reader and writer as a child and thereby learn how to strengthen the controlling function of your prefrontal cortex by creating an organized mind based on scientific knowledge and secular humanism during your youth.
Since there is great competition within brain structures between the prefrontal cortex (with its ability to imagine, reason, and remember) and the limbic system (with its ability to express emotions), for example, the ability of an adult to think logically and control the strongest emotions, is not as easy until about the mid-30s.
In other words, the strong bonding feelings that are evoked by the social peer groups in the second decade of life (think, teenagers) are hard for individuals to overcome until the prefrontal cortex part of the two hemispheres of their cerebrum are fully developed sometime between their mid-20s to mid-30s.
When you understand your authentic secular self from this new perspective of humanistic and scientific reasoning, your self-identity, which you construct from your life experiences, is the real deal. It is not some fanciful illusion or twisted delusion or exotic hallucination, but truly genuine reality.
Unfortunately, your limbic system can also preserve a lot of useless, dysfunctional memories of bad social habits and mindsets, including a variety of addictions. You may have learned many useless behaviors in your childhood and youth before you learned to be self-disciplined through proper education to establish predictable adult control over your feelings.
DEFINITION OF LIMBIC SYSTEM =
The set of brain structures situated along the inner borders of both temporal lobes of both hemispheres of your cerebrum at the most protected lower part of your brain. It's emotional functions are crucial for you to be able to express your feelings, to organize your memories, to mediate or coordinate your conscious self-awareness, and to interpret the behavior of others, which is known as "psychology of mind".
Nevertheless, the eight vital brain structures of your limbic system produce many kinds of neurotransmitters, which can stimulate your 100-200 billion neurons. The names of the eight crucial structures of your limbic system follow:
 OLFACTORY BULBS
 PITUITARY GLAND
 AMYGDALA GLANDS
 PINEAL GLANDS
 BASAL GANGLIA
