7 Safe Sports for Asthma Sufferers

The limbic system is the part of the brain that is responsible for regulating emotions, behavior and memory. This system also plays a role in controlling basic body functions related to survival.

The limbic system is located within the cerebrum which is the largest part of the human brain, precisely under the temporal lobe. This system consists of several parts that work together to regulate emotional responses, memory, motivation, reactions to stress or threats, and learning ability.

Parts of the Limbic System and Their Roles

The limbic system processes information received from the surrounding environment and studies it, then determines the appropriate response or reaction based on that information.

So, this system is responsible for processing experienced events, learning from them, and influencing the way a person acts and feels.

Each part of the limbic system has a different role in regulating emotions, memory, and the body's response to certain situations. For more details, the following are the parts of the limbic system and their functions:

1. Hippocampus

The hippocampus plays a role in the formation, processing and storage of memory, both short and long term . This part of the limbic system makes you able to remember directions and locations and associate certain smells with memories, for example the smell of food your grandmother cooked when you were little.

Apart from that, the hippocampus also plays a role in the process of forming new nerve cells (neurogenesis), which supports learning and memory abilities. Damage to this part of the limbic system can cause memory disorders, such as Alzheimer's disease..

2. Amygdala

Amygdala is the limbic system that plays a role in regulating emotions and behavioral responses. The amygdala controls emotional reactions, such as fear, anger, anxiety, and happiness, and processes emotional memories. That way, we will be able to remember events related to emotions. 

The amygdala also plays a role in making decisions that are influenced by emotional conditions. Problems with the limbic system are associated with anxiety disorders, PTSD, panic disorders, and phobias.

3. Hypothalamus

The hypothalamus is part of the limbic system that regulates the release of hormones to control various body functions, such as temperature body, thirst and hunger, sleep cycles, sexual arousal, and response to stress. This part of the brain also plays a role in controlling blood pressure and heart rate.

Damage to the hypothalamus can cause unexplained weight changes, insomnia, delayed puberty, stress, fatigue, and excessive sex drive.

4. Basal ganglia

The basal ganglia are located beneath the cerebral cortex which plays a role in controlling movement, motor learning, as well as behavior and emotions. Ensuring that movements are coordinated and preventing unwanted movements is the job of the basal ganglia.

The basal ganglia also helps you feel satisfaction when doing something enjoyable and assess how important and risky a goal is. This will later influence your decision. Apart from that, the basal ganglia also helps you remember actions that produce positive things and repeat these actions as a habit.

Disorders of the basal ganglia, such as Parkinson's disease, Huntington's disease, Tourette's syndrome, disease Wilson, and stroke, can cause motor problems, such as tremors, muscle stiffness, and body balance disorders.

The function of the limbic system is very important for survival. Therefore, this part of the brain needs to be kept in good health. There are several ways that you can apply to maintain the health of the limbic system and brain function the whole, namely:

  • Consume food that is good for the brain, such as fish, eggs, nuts, spinach, broccoli, kale, avocado, strawberries, apples, mushrooms, potatoes and turmeric.
  • Regular exercise, such as walking, running, or yoga, increases blood flow to the brain and stimulates the production of hormones that are good for brain, including those that support the function of the limbic system.
  • Cope with stress well, such as meditation or exercise mindfulness, to maintain hormonal balance.
  • Make sure to sleep for 7–9 hours every day and rest when you feel tired.
  • Be active in social activities or activities you enjoy to stimulate cognitive function, improve mood, and reduce the risk of brain decline as you get older
  • Avoid drugs because they can damage brain function.

These are the parts of the limbic system and their respective roles. Considering that disorders of the limbic system can affect the quality of life, it is a good idea for you to consult a doctor via Chat with a Doctor to monitor lifestyle patterns that support overall brain health.
