Emotion, in its most general definition, is an intense neural impulse-produced mental state that arises subjectively rather than through conscious effort and evokes either a positive or negative psychological response.
Based on discoveries made through neural mapping of the limbic system, the neurobiological explanation of human emotion is that emotion is a pleasant or unpleasant mental state organized in the limbic system of the brain. Specifically, these states are manifestations of non-verbally expressed feelings of agreement, anger, certainty, control, disagreement, disgust, disliking, embarrassment, fear, guilt, happiness, hate, interest, liking, love, sadness, shame, surprise, and uncertainty.
Emotions are elaborations of arousal patterns, in which neurochemicals (e.g., dopamine, noradrenaline, and serotonin) step-up or step-down the brain's activity level, as visible in body movements, gestures, and postures.
Primary emotions, such as fear, "depend on limbic system circuitry," with the amygdala and anterior cingulate gyrus being "key players".
Secondary emotions, events, and situations through learning) require additional input from the prefrontal and somatosensory cortices. The stimulus may still be processed directly via the amygdala but is now also analyzed in the thought process. Thoughts and emotions are interwoven: every thought, however bland, almost always carries with it some emotional undertone, however subtle.

Billy's answer was spot on! The only thing I could add is that emotion is an unconscious reaction to some aspect of our environment. We store every experience of our lives in our unconscious (sometimes referred to as sub-conscious) and use them unconsciously to help us interpret our current situation. Our unconscious can sort and compare present to past almost instantly whereas doing so consciously would take so long as to preclude any timely response. Since we are unconscious of this process, our brain communicates these comparative evaluations through our emotions.
Have you ever experienced a sense of fear without understanding why, only later to find some inobtrusive, non-threatening source that you laughed about scaring you? Your brains sensory cortex identified some sound, smell, sight, something that in your past has been associated with a threat and communicated that by activating the brains fear center, the amygdala. Billy's answer mapped out the neurological response, but the result is that your "feeling" or emotion causes us to pause and consciously evaluate our environment for an appropriate response. So our emotions are the way our unconscious communicates with our conscious.
An excellent (and probably more understandable) treatment of this is found in the book "The Psychology of Self Esteem" by Nathaniel Brandon.

I'm sure you'll receive a plethora of answers on this. For me, chemically speaking- I get extremely anxious when I am faced in a situation I cannot control because I have clinical depression- the serotonin levels are out of whack and sometimes I can't handle emotions- I know what causes them and what to do to avoid certain sitautions from arising. Mad creates anger, sometimes I may be alone but I'm not lonely. Does that make sense? Thank you for the question- it's a good one.

There is one part in your brain,the frontal lobe,it controls all emotional effects in your body.
