Let's learn about the secret center of the brain (Limbic System) that controls your emotions.

Imagine that you are walking down the street and suddenly a dog jumps in front of you. You startle and get scared, your heart beats faster, and your body becomes cold. Or, when you see your favorite food, your mouth drools and you feel incredibly happy. When you hear an old song after many years, you are suddenly transported back to your school days. Who knows what is behind all this? That is the king of our emotions hidden deep in our brain - the Limbic System . This is the main center that controls many things such as our emotions, memory, and behavior. Today, we will talk about this amazing system.

Simply put, what is the limbic system?

The limbic system is not just one part of the brain. It is a collection of parts that work together, like the departments of a company working together. All of these parts are interconnected and control our emotions, behavior, memories, and the basic things that help us survive.

This is also said to be the oldest part of our brain. That means that our ancestors, that is, early humans, controlled the instincts that helped them survive through this limbic system. Imagine, in order for people to survive at that time:

• I need to find food and drink.
• Need to escape from enemies (fight or flight response).
• They want to breed their own kind.
• They need to take care of their children.

The limbic system is what created the emotions and behaviors that are necessary for all of this. Things like the urge to look for food when you're hungry, the urge to run when you see danger, the urge to love when you see your child, all come from here. We still have this same instinct today.

Why is this also called the 'emotional nervous system'?

Another name for this is the 'Emotional Nervous System'. That means "the nervous system related to emotions." The reason for saying that is because the limbic system controls the strong connection between our physical well-being and mental well-being.

For example, imagine that you are hungry. At that time, you eat food. When you eat your favorite food, you feel very happy and satisfied, right? That feeling of happiness is created by the limbic system. Also, when you are under a lot of stress due to some problem, your blood pressure increases, and your heart rate increases. The limbic system also creates this physical response.

The main members of the limbic system and their functions

As we said before, this is a team that works together. There are four main members of this team. Let's see who they are and what they do. To make this easier to remember, let's use short nicknames for these parts.

The relationship between smell and the limbic system

Remember in the table above that we said that the thalamus doesn't receive olfactory information? There's a special reason for that. Our sense of smell (olfactory bulb) is directly connected to the amygdala and hippocampus, which are parts of the brain that are involved in emotions and memory.

That's why when we smell certain scents, we immediately recall old memories and have associated emotions.

• When you smell the incense sticks being lit in a temple, does it suddenly bring you comfort and peace, remembering how you used to go to the temple to pray with your grandmother when you were a child?
• Do you love the smell of a new book? It can remind you of your first day of school.
• The smell of a special dish cooked by mom can remind you of home and make you feel both happy and sad.

All of this happens because of this strong, direct connection between smell and the limbic system.

What happens if something goes wrong with the limbic system?

Since this system controls our emotions and memory, any weakness in its functioning can lead to various mental and neurological conditions. It's like a company's management team failing to function properly, causing the entire company to collapse.

Common symptoms in this situation

If there is a condition affecting the limbic system, one or more of the following symptoms may occur.

• Sudden changes in mood: frequent anger, quick temper, feeling scared for no reason, feeling extremely sad.
• Memory impairment: Difficulty remembering new things, forgetting old things.
• Sleep problems: sleeping too much (hypersomnia) or not sleeping (insomnia).
• Behavioral changes: Becoming withdrawn, losing interest in things you used to enjoy.

Let's learn about diagnosis and treatment.

When you go to see a doctor with symptoms like these, he or she will likely run several tests to find the cause.

• Neurological exam: Checking your balance, reflexes, and other nervous system functions.
• Psychological evaluation: Asking questions to get information about your feelings, thoughts, and behavior patterns.
• Scans such as MRI: Tests such as Magnetic Resonance Imaging (MRI) can be performed to look at the structure of the brain and see if there are any changes in it.

Treatment options vary depending on the diagnosis, but may generally include:

• Medications: Medications given to balance brain chemicals.
• Counseling or therapy: Talking to a mental health counselor and learning to manage your emotions.
• Lifestyle changes: Calming the mind through things like exercise, yoga, and meditation.
• Deep Brain Stimulation (DBS): A specialized treatment used in some severe cases.

The most important thing is that your doctor will determine the best treatment for you, so be sure to follow his or her instructions.

So how do we keep this limbic system healthy?

There are many simple things we can do to keep this bridge between our emotions and physical health strong. These are very good for your limbic system and your entire body.

• Eat a well-balanced diet: Eat a balanced diet. Eat more vegetables, fruits, and greens. Include foods that contain brain-healthy nutrients like omega-3 (e.g., small fish).
• Exercise regularly: Do at least 30 minutes of moderate exercise a day. Anything like walking, running, or swimming is good. Exercise releases feel-good hormones.
• Spend time with people you love: Talking and laughing with family and friends is very important for mental health.
• Make time for things you enjoy: Doing things like engaging in a hobby, listening to music, or watching a movie can help reduce stress.
• Stay away from drugs and alcohol: Although these provide short-term pleasure, they cause great damage to the brain and limbic system in the long run.
• Manage stress: Take a break when you feel stressed. Breathe deeply. Meditate.
• Control other medical conditions: If you have any medical conditions like diabetes or high blood pressure, control them properly, as they can also affect brain health.
