What Part Of The Brain Controls Emotions

We have a variety of emotions ranging from sad to extremely happy and sometimes we can not make sure what kind of emotional state are we in?

What Part Of The Brain Controls Emotions?

There are certain structures in our brain that control our emotions and collectively we called those structures a system. i.e Limbic System.

Structures

The limbic system consists of the following structures,

  1. Hippocampus
  2. Amygdala
  3. Hypothalamus
  4. Cingulate gyrus

Functions

Together, the Limbic system has the following functions,

  • Emotional responsiveness
  • Motivation
  • Memory function and integration
  • Olfaction
  • Autonomic Nervous System

Limbic System

The limbic system is one of the most primitive systems and one of the first to develop fully in children. That is the reason kids are full of emotions.

Many pharmacological drugs acts on limbic system and manipulate our mood especially in depression.

Most of the Anti-Depressants act on limbic system and increase certain types of neurotransmitters which in turn elevates mood.

Limbic system structures are involved in many of our emotions and motivations, particularly those that are related to survival. Such emotions include fear, anger, and emotions related to sexual behavior.

What Part Of The Brain Controls Emotions

The limbic system is also involved in feelings of pleasure that are related to our survival, such as those experienced from eating and sex. Certain structures of the limbic system are involved in memory as well.

Two large limbic system structures, the amygdala, and hippocampus play important roles in memory.

The amygdala is responsible for determining what memories are stored and where the memories are stored in the brain.

It is thought that this determination is based on how huge an emotional response an event invokes.

The hippocampus sends memories out to the appropriate part of the cerebral hemisphere for long-term storage and retrieves them when necessary.

Damage to this area of the brain may result in an inability to form new memories. Part of the forebrain known as the diencephalon is also included in the limbic system.

The diencephalon is located beneath the cerebral hemispheres and contains the thalamus and hypothalamus.

The thalamus is involved in sensory perception and regulation of motor functions (i.e., movement).

It connects areas of the cerebral cortex that are involved in sensory perception and movement with other parts of the brain and spinal cord that also have a role in sensation and movement.

The hypothalamus is a very small but important component of the diencephalon. It plays a major role in regulating hormones, the pituitary gland, body temperature, the adrenal glands, and many other vital activities.

Summary

What part of the brain controls emotions? Yes, The limbic system is responsible for controlling various functions in the body.

Some of these functions include interpreting emotional responses, storing memories, and regulating hormones. The limbic system is also involved with sensory perception, motor function, and olfaction.
