Emotions, are more likely to be felt, and less likely to be understood.
While living some emotional experiences, it is not common to try to figure out where the emotions come from. Whether it is anger, happiness, fear or any other sensation, our emotions are not, as some scientists claim, divided on our body parts.
According to the NYTimes, our emotions, each one of them, has an essence in either our brain or body. When an emotion arises due to a triggering event, a physical reaction is related to its. We can witness the rise of our blood pressure as a consequence of anger, or the sadness neuron breed in the form of a stomach ache as a consequence of the loss of a loved one. As a matter of fact, similar experiences are considered as the only biological proof of emotions in a human body.
The challenge that scientists face is to be able to locate the fingerprints of emotions, and to identify the emotions from body changes and brain’s signals. While some scientists fight to locate the emotions on the human body, some struggle in order to prove the existence of these fingerprints, while others deny any evidence of it.
Neuroscience, as a matter of course, studied brain-imagining experiences in order to define emotions according to it. The most astonishing discovery was that each emotion did not belong to a specific brain region, and that every alleged emotion region of the brain, had an increased activity during none-emotional thoughts and perceptions.
The word “Amygdala” refers to the most well-known emotional region of the brain. While some experiences defended the fact that fear is strongly related to amygdala, the scientific experience of two identical twins (“BG” and “AM” according to the scientific literature) proved that the amygdala-fear relationship is nothing but a theory with no evidence. The twins, both suffered from a genetic disease obliterating their amygdala. Thus, BG was not capable of experiencing fear in the utmost situations, while AM had a normal emotional recognition. In conclusion, the amygdala, such as many different brain areas, participates in several mental events. Fear and anger for instance are constructed by multipurpose brain networks working simultaneously.
According to Charles DARWIN, spices are a population of varied individuals who tend to change according to their environment. From an analogical point of view, emotions vary according to the context, and the norm is actually in variation. Thus, according to this article, the challenge is not in identifying the emotions location nor origin, but rather in discovering how the human brain is capable of producing similar experiences.
