I know the title, I can't remember.

Why did I choose this subject?

I encounter presque vu quite a bit in everyday life. It's a rather annoying experience to be on a roll in a conversation, then suddenly forget what you're about to say, and by the time you remember, the subject's already changed. My research flyer will help to educate others on the syndrome and how to prevent this from happening.

What is Presque Vu?

Have you ever been in a conversation and you suddenly forget what you're about to say, but you know that you know it, and it's right on the tip of your tongue? This occurrence is known as presque vu.Presque vu is a pretty common experience to us all, and an annoying one to boot. Presque vu is more commonly known as "Tip of the Tongue," (TOT) syndrome. TOT happens when the left temporal and frontal lobes of your brain fail to communicate in transferring little tidbits of information, such as celebrity names, favorite songs, and where the remote is. TOT syndrome occurs frequently, yet little research has been conducted due to its random nature.

What's happening in the brain?

We believe presque vu occurs when primarily two parts of the brain, the frontal and temporal lobes, fail to communicate and transfer information, but granting the person a feeling of imminent retrieval, hence why we say "It's on the tip of my tongue, I just know it!"

The disconnect is usually temporary, but can last longer in patients suffering from brain damage.

Research done on TOT

There is no way to trigger presque vu in lab settings, it's a relatively random experience that happens during the day. On the rare moments that we have managed to capture TOT in an MRI machine, the frontal and temporal lobes are the most active, along with the motor cortex, surprisingly, hence why people experiencing presque vu show increased movement, such as exaggerated hand gestures. There's no concrete theory on the subject, only mere speculations about the phenomenon.

Interesting ways to prevent presque vu

- Clenching your right fist can help stimulate your memory by changing up the signals being processed in your brain, effectively restarting as you would with a frozen computer.
- Speak words that may be spelled or sound similar to the word you're trying to remember
- Associate the word you're looking for with a picture to help you retrieve the information.
