6 ways the Limbic system affects physical, emotional and mental health

The man sitting near the bench in a park, meditationThe body system is a set of brain structures that play a role in emotions, especially those that evolved early and play an important role in survival.

Research has linked the restrictive system to motivation and reward, learning, memory, response to wrestling or flight, hunger, thirst, and the production of hormones that help regulate the autonomic nervous system. The autonomic nervous system supports automatic, unconscious functions such as thirst, hunger, heart rate, and internal body clock adjustment.

What is the Limbic system?

The body system is not a particular organ or part of the body, but a group of brain structures that cooperate.

It includes the hippocampus and the amygdala, each of which is actually a pair of organs on both sides of the brain. Hippocampi play an important role in memory, learning, long-term storage of information and spatial logic. Almonds help the body process emotions. They also help to attach emotional significance to memories. Problems with these two instruments can affect memory, learning and emotional regulation.

The marginal system also includes the hypothalamus. This instrument plays a role in myriad functions by releasing hormones that help maintain homeostasis – the ability of the body to maintain relatively stable conditions. Other marginal organs of the system include neurons, basal ganglia, parts of the frontal cortex, cylindrical node and ventricular puncture area.

What does the Limbic system do?

The body system functions as a control center for conscious and unconscious functions, regulating much of what the body does. In some ways, it connects the mind with the body, bridging the gap between psychological and physiological experiences. For example, by activating the race or flight reaction, the body system activates a natural response to emotional experiences such as fear. The body system functions as a control center for conscious and unconscious functions, regulating much of what the body does.

1. Reward, Incentives and Addiction

Surveys suggest that motives of motivation and reward come from the ventral segmental segment (VTA), a group of neurons associated with the accumbens nucleus in the basal ganglia. These neurons release dopamine, a neurotransmitter that supports the feelings of pleasure.

In a healthy brain, dopamine helps people feel motivated to learn, to meet new people or to experience new experiences. Drug and alcohol abuse, however, can change the functioning of the fishing system. Drugs act on dopamine and, over time, release of dopamine can become addictive. Over time, addiction can ruin dopamine brain stores, making it difficult to feel free of pleasure. That is why many people with addictions find little relief from activities that were once pleasant.

2. Emotional Answers

The amygdala and the hippocampus work together to regulate emotions, especially evolutionary "old" emotions that play a role in survival – love for children, aggression, fear and anxiety.

Together, these two instruments also help the brain to interpret the emotional content of memories. Amygdala gives emotional meaning to memories and helps the brain to form fears based on memories. The hippocampus helps to create sensory memories, which are memories associated with sensory introduction. When the smell of a crispy apple or hot air on the beach brings back the memories of a summer before, the hippocampus is responsible.

3. Fight or flight

The body system helps the body respond to intense feelings of fear and anger, triggering the response of the race or flight. This reaction is also called combat, flight or freezing response, thanks to new evidence suggesting the role of freezing in response to the risk.

When the almond perceives a threat, it activates the limbic system to prepare itself to handle the threat. Adrenal glands release hormones such as epinephrine that increase blood pressure and heart rate, improve blood flow to the muscles and organs and increase breathing rate.

In the short term, responding to combat or flight may be life-saving. Over time, however, chronic stress can trigger the limiting system in a way that damages the body. The long-term release of epinephrine and other hormones can damage blood vessels, cause high blood pressure and change appetite.

4. Memory

Both the amygdala and the hippocampus help the brain to form new memories, store them, retrieve them, and make sense of their emotional content. Hippocampus is particularly important for long-term memory formation. It also supports spatial memory and spatial logic.

5. Hormones that affect the automatic functions

Hormones are chemical messengers of the body, they send a signal from one area to the body in response to environmental inputs and other information.

The hypothalamus releases hormones that play a role in a wide range of emotions, such as pain, hunger, thirst, pleasure, sexual feelings, anger, and aggression. It also helps the body maintain a homeostatic state by regulating the autonomic nervous system. Some examples of this feature include:

  • Getting information from the lung nerve for blood pressure and how full is the stomach. Using this information, it releases chemicals that regulate appetite and blood pressure.
  • Collecting information from the grid formation of the brain stem about temperature and then using it to manage the body's response to heat or cold.
  • Adjusting the body's internal clock, circadian rhythm, based on light, darkness and other sensory inputs.

6. Attention and learning

Helping the brain to create new memories, the body system helps the body learn and remember the information. It also plays a role in regulating cognitive attention. Research shows, for example, that gyrus cingulate focuses brain attention on emotionally important events. The foreleg can also help with conscious efforts to control emotions.

Some research shows that people with attention deficit hyperactivity disorder (ADHD) have an enlarged hippocampus. This may be the body's effort to compensate for problems with hippocampal's ability to regulate attention.

The brain creates new stem cell neurons in the hippocampus, indicating that the hippocampus and the emotions and memories it supports can be changed with new experiences. This ability of the hippocampus to change over time supports the ability to learn new things. Research on the brains of people with Alzheimer's and other forms of dementia has found that the disease attacks the hippocampus. This may explain why dementia so quickly undermines the ability to learn new things, even as memories have long been intact.

The limbic system is dynamic, it changes with the entrance of a person's environment. Experience changes this important area of ​​the brain and this can explain why people's psychological and physiological experiences change over time. Treatment can also change the body system, promoting the brain to process information differently, assigning new emotions to old memories or supporting a client in managing chronic stress.

Many disorders can damage the body system. Memories and experiences are also important. Treatment can help people understand these experiences, improve some of the effects of chronic stress, help a person better manage their feelings and possibly reduce the risk of stress-related disorders such as cardiovascular disease .
