What is Déjà vu?
Vsauce・6 minutes read
Déjà vu is a phenomenon tied to brain development, occurring most in young adults, possibly linked to neurological abnormalities like synchronized neuron firing or brain damage. Similar experiences include Hypnagogic Jerk, Presque vu, and Jamais vu, all stemming from different cognitive processes and brain functions.
Insights
- Déjà vu is most common in teens and twenties, potentially linked to brain development, with neurological abnormalities like synchronized neuron firing during epileptic episodes or brain damage in the temporal lobes being possible causes.
- The brain processes visual information through various structures, with blindsight in some blind individuals potentially leading to a disconnect that could result in déjà vu, along with other related experiences like Presque vu and Jamais vu due to neuron inhibition from overstimulation.

What is déjà vu?
Déjà vu is a phenomenon where a current situation feels familiar, occurring most frequently in teens and twenties before tapering off with age. It may be linked to brain development.
How does the brain process visual information?
The brain processes visual information through various structures, with preliminary parts potentially causing blindsight in some blind individuals. This may lead to a disconnect that can result in déjà vu.
What neurological abnormalities can cause déjà vu?
Déjà vu may be caused by a neurological abnormality, such as synchronized firing of neurons during an epileptic episode, or brain damage in the temporal lobes.
What is Hypnagogic Jerk?
Hypnagogic Jerk is a common phenomenon where falling asleep triggers a sensation of falling, causing muscle twitches to wake the body up.
What are similar experiences to déjà vu?
Other similar experiences to déjà vu include Presque vu, where one struggles to recall a familiar word, and Jamais vu, where something known suddenly feels unfamiliar. These experiences may be due to neuron inhibition from overstimulation.
