Emotions are the feelings or feelings that arise in the mind when encountering a  certain phenomenon or event. There are many types of emotions, such as anger,  irritability, and fear. To find out the causes of these emotions,

first, there are physiological and physical causes. Emotions are accompanied by  their causes in the body, for example, fear arises when there is no place to rely  on the body, anger arises when the body is deprived of freedom, stimulation of  any part of the body produces pleasure, armpits or Tickling the sole of the foot  causes laughter, and hitting the body hard causes pain. 

Second, there are psychological causes. This is the principle that emotions arise  in relation to the required level, and when the required level is reached, a sense  of success occurs, and when the required level is not reached, a sense of failure  occurs. The main emotions are happiness and unhappiness.

Finally, there are social causes. This is a relationship with other people, and  when the problem of the level of demand and grades is entangled, various  emotions arise. There is a feeling of victory and defeat, a feeling of inferiority  when dealing with an unbearable opponent, and a feeling of superiority in the  opposite case. Also, anger when self-esteem is damaged, and love and hatred  between people. 

Like this, Our emotions arise from the physiological reactions of the brain caused by  various stimuli.

First, emotions have evolved to stimulate human survival and prosperity by triggering  certain behaviors. All emotions are created in a busy system located just below the  cerebral cortex. The amygdala, the primary receptor, signals other areas of the brain  to produce an appropriate emotional response to all incoming stimuli. The connection  system and the cerebral cortex are connected to each other so that they can be aware  of and feel emotions. At this time, emotions are handled through unconscious and  conscious pathways. All sensory information enters the award, and the unconscious

path refers to the amygdala's evaluation of information as soon as it occurs. It also  sends signals to other areas to cause immediate physical reactions. On the other hand,  the conscious path sends sensory information that enters the body to the amygdala  while also sending it to the cerebral cortex. In other words, this is done more slowly,  consciously, and takes more time than the unconscious route.
