Medical Video: 10 Intriguing Theories Explaining Déjà Vu
Dejavu is a situation where you feel familiar with the conditions around you, as if you have experienced it in exactly the same situation, even though what you are experiencing now is probably your first experience. This event can last 10 to 30 seconds, and more than once. If this happens to you, you don't need to panic, because according to some studies, two to three people who have experienced dejavu will experience it again.
Dejavu aka "déjà vu" comes from French which means "I've seen". This title was first coined by Émile Boirac, a French philosopher and scientist in 1876. Many philosophers and other scientists tried to explain why dejavu could occur. According to Sigmund Freud, the occurrence of dejavu is related to pent-up desires. While according to Carl Jung, dejavu is related to our subconscious.
Certain explanations regarding the reasons for déjà vu are difficult to find because the study of dejavu itself is not easy to do. Researchers can only hold on to someone's retrospective dejavu experience, making it difficult to find the stimulus that triggers the dejavu.
But there are several theories that might answer why you experience dejavu:
Dejavu because temporal lobe seizure
Cause temporal lobe seizure aka temporal lobe seizures are sometimes unknown. But trauma to the brain, infections, strokes, brain tumors, and genetic factors can cause it temporal lobe seizure. When experiencing an attack, sufferers temporal lobe seizure can experience a decrease in the ability to respond to the surrounding environment to carry out the same activities over and over again such as clicking the tongue or moving the fingers unnaturally. Before this attack comes, usually sufferers temporal lobe seizure will experience strange sensations such as feeling unreasonable fear, hallucinations, and dejavu.
Dejavu because of brain circuit malfunctions
Between malfunctions can occur long term circuits and short term circuits in our brain. When the brain digests the surroundings, the information obtained can be directly transferred to the part of the brain that holds long-term memory. This causes us to feel the dejavu, as if we have seen and felt the events we have experienced in the past.
Dejavu because of work rhinal cortex
Section called rhinal cortex in our brain functions to detect familiar feeling. This part may be activated without triggering the work of the hippocampus (the part of the brain that functions as memory). This can explain why when we experience dejavu, we cannot remember exactly when and where we experienced the same experience.
Dejavu is more often reported by sufferers temporal lobe seizure and epilepsy sufferers. What causes dejavu to occur in normal and healthy individuals is still unknown.
