I was sitting on a couch in the commons thinking about a topic to write for my fifth and final blog. One of my friends, walked up, and sat down next to me. We began to talk about how our day went, and the immense amount of homework we still had yet to do. So we stood up, and began walking toward the Findlay Computer Lab. I took a few steps, but then I had to stop. This scenario had definitely happened before. I have already lived this moment so far, or so I thought. I experience the phenomenon commonly referred to as déjà vu. It has happened to us all, but is there a scientific explanation for these strange occurrences.
Contrary to what you would believe, scientists are able to test déjà vu in a laboratory. Scientists ask participants to scan the familiarity of faces or places they’ve seen before, and others they have not seen before. Scientists have concluded that during recognition, recollection, and familiarity are two different things. Different parts of the brain correspond with familiarity and recognition. Familiarity triggers the temporal lobe in the brain. When people are distinguishing between things they’ve seen and things they’ve not seen, it triggers the parahippocampus cortex of the brain.
Another theory by scientists is a glitch in our memory process. It could also be confused with precognitive experiences, which is an experience where one gets a feeling that they know exactly what’s going to happen next, and it does. There are other interesting theories that scientists believe to be true. One explanation for deja vu is that there is a split-second delay in transferring information from one side of the brain to the other. One side of the brain would then get the information twice. So the person would sense that the event had happened before.
Déjà vu proves to be a mystery time and time again. There is no known scientific explanation for this strange phenomenon. There are many theories, some of which I shared above, that scientists believe to be true. I think Déjà vu is one of the most interesting things that happen inside of our brain. Wait…I think I wrote this blog before…
I experience deja vu so frequently. Watch this video about deja vu. They say that deja vu:
-happens most frequently between the ages of 15-25.
– is hard to track scientifically.
-increases activity in the temporal lobe.
-finds similar memory in hippocampus.
-has much to do with the rhinal cortex.
I have had the wrong belief of Deja vu for my entire life. I always believed it to be when you dreamt and when you woke up, that actual scenario occurred in real life. Your information is very in depth and changed my viewpoint.
