Dialogue: 0,0:00:08.29,0:00:12.54,Default,,0000,0000,0000,,It's that shadowy feeling you get\Nwhen a situation seems familiar.
Dialogue: 0,0:00:12.56,0:00:15.53,Default,,0000,0000,0000,,A scene in a restaurant plays out\Nexactly as you remember.
Dialogue: 0,0:00:15.55,0:00:18.34,Default,,0000,0000,0000,,The world moves like a ballet\Nyou've choreographed,
Dialogue: 0,0:00:18.36,0:00:20.84,Default,,0000,0000,0000,,but the sequence can't be based\Non a past experience
Dialogue: 0,0:00:20.86,0:00:23.38,Default,,0000,0000,0000,,because you've never eaten here before.
Dialogue: 0,0:00:23.40,0:00:25.30,Default,,0000,0000,0000,,This is the first time you've had clams,
Dialogue: 0,0:00:25.33,0:00:26.74,Default,,0000,0000,0000,,so what's going on?
Dialogue: 0,0:00:26.76,0:00:30.46,Default,,0000,0000,0000,,Unfortunately, there isn't\None single explanation for déjà vu.
Dialogue: 0,0:00:30.49,0:00:33.11,Default,,0000,0000,0000,,The experience is brief\Nand occurs without notice,
Dialogue: 0,0:00:33.14,0:00:36.69,Default,,0000,0000,0000,,making it nearly impossible\Nfor scientists to record and study it.
Dialogue: 0,0:00:36.71,0:00:40.07,Default,,0000,0000,0000,,Scientists can't simply sit around\Nand wait for it to happen to them --
Dialogue: 0,0:00:40.09,0:00:41.20,Default,,0000,0000,0000,,this could take years.
Dialogue: 0,0:00:41.22,0:00:43.34,Default,,0000,0000,0000,,It has no physical manifestations
Dialogue: 0,0:00:43.36,0:00:44.55,Default,,0000,0000,0000,,and in studies,
Dialogue: 0,0:00:44.58,0:00:47.54,Default,,0000,0000,0000,,it's described by the subject\Nas a sensation or feeling.
Dialogue: 0,0:00:47.57,0:00:49.39,Default,,0000,0000,0000,,Because of this lack of hard evidence,
Dialogue: 0,0:00:49.41,0:00:52.38,Default,,0000,0000,0000,,there's been a surplus\Nof speculation over the years.
Dialogue: 0,0:00:52.41,0:00:54.72,Default,,0000,0000,0000,,Since Emile Boirac introduced déjà vu
Dialogue: 0,0:00:54.75,0:00:57.06,Default,,0000,0000,0000,,as a French term meaning "already seen,"
Dialogue: 0,0:00:57.08,0:01:00.44,Default,,0000,0000,0000,,more than 40 theories attempt\Nto explain this phenomenon.
Dialogue: 0,0:01:00.46,0:01:04.74,Default,,0000,0000,0000,,Still, recent advancements in neuroimaging\Nand cognitive psychology
Dialogue: 0,0:01:04.76,0:01:06.64,Default,,0000,0000,0000,,narrow down the field of prospects.
Dialogue: 0,0:01:06.66,0:01:09.70,Default,,0000,0000,0000,,Let's walk through three of today's\Nmore prevalent theories,
Dialogue: 0,0:01:09.73,0:01:11.81,Default,,0000,0000,0000,,using the same\Nrestaurant setting for each.

Dialogue: 0,0:01:13.76,0:01:14.76,Default,,0000,0000,0000,,We'll need an action.
Dialogue: 0,0:01:14.79,0:01:17.37,Default,,0000,0000,0000,,Let's go with a waiter\Ndropping a tray of dishes.
Dialogue: 0,0:01:17.40,0:01:18.59,Default,,0000,0000,0000,,As the scene unfolds,
Dialogue: 0,0:01:18.61,0:01:21.69,Default,,0000,0000,0000,,your brain's hemispheres process\Na flurry of information:
Dialogue: 0,0:01:21.72,0:01:23.21,Default,,0000,0000,0000,,the waiter's flailing arms,
Dialogue: 0,0:01:23.23,0:01:24.25,Default,,0000,0000,0000,,his cry for help,
Dialogue: 0,0:01:24.27,0:01:25.75,Default,,0000,0000,0000,,the smell of pasta.
Dialogue: 0,0:01:25.78,0:01:28.87,Default,,0000,0000,0000,,Within milliseconds, this information\Nzips through pathways
Dialogue: 0,0:01:28.89,0:01:31.29,Default,,0000,0000,0000,,and is processed into a single moment.
Dialogue: 0,0:01:31.31,0:01:33.87,Default,,0000,0000,0000,,Most of the time,\Neverything is recorded in-sync.
Dialogue: 0,0:01:33.89,0:01:35.25,Default,,0000,0000,0000,,However, this theory asserts
Dialogue: 0,0:01:35.27,0:01:37.100,Default,,0000,0000,0000,,that déjà vu occurs\Nwhen there's a slight delay
Dialogue: 0,0:01:38.02,0:01:40.30,Default,,0000,0000,0000,,in information from one of these pathways.
Dialogue: 0,0:01:40.32,0:01:41.80,Default,,0000,0000,0000,,The difference in arrival times
Dialogue: 0,0:01:41.82,0:01:44.18,Default,,0000,0000,0000,,causes the brain to interpret\Nthe late information
Dialogue: 0,0:01:44.20,0:01:45.74,Default,,0000,0000,0000,,as a separate event.
Dialogue: 0,0:01:45.77,0:01:48.02,Default,,0000,0000,0000,,When it plays\Nover the already-recorded moment,
Dialogue: 0,0:01:48.04,0:01:49.76,Default,,0000,0000,0000,,it feels as if it's happened before
Dialogue: 0,0:01:49.78,0:01:51.98,Default,,0000,0000,0000,,because, in a sense, it has.
Dialogue: 0,0:01:52.91,0:01:55.35,Default,,0000,0000,0000,,Our next theory deals\Nwith a confusion of the past
Dialogue: 0,0:01:55.37,0:01:57.40,Default,,0000,0000,0000,,rather than a mistake in the present.
Dialogue: 0,0:01:57.43,0:01:59.24,Default,,0000,0000,0000,,This is the hologram theory,
Dialogue: 0,0:01:59.26,0:02:01.53,Default,,0000,0000,0000,,and we'll use that tablecloth\Nto examine it.
Dialogue: 0,0:02:02.07,0:02:03.35,Default,,0000,0000,0000,,As you scan its squares,
Dialogue: 0,0:02:03.37,0:02:06.27,Default,,0000,0000,0000,,a distant memory swims up\Nfrom deep within your brain.
Dialogue: 0,0:02:06.29,0:02:07.49,Default,,0000,0000,0000,,According to the theory,
Dialogue: 0,0:02:07.51,0:02:09.20,Default,,0000,0000,0000,,this is because memories are stored
Dialogue: 0,0:02:09.23,0:02:10.60,Default,,0000,0000,0000,,in the form of holograms,
Dialogue: 0,0:02:10.63,0:02:11.72,Default,,0000,0000,0000,,and in holograms,
Dialogue: 0,0:02:11.74,0:02:14.20,Default,,0000,0000,0000,,you only need one fragment\Nto see the whole picture.
Dialogue: 0,0:02:14.22,0:02:17.25,Default,,0000,0000,0000,,Your brain has identified the tablecloth\Nwith one from the past,
Dialogue: 0,0:02:17.28,0:02:18.99,Default,,0000,0000,0000,,maybe from your grandmother's house.
Dialogue: 0,0:02:19.02,0:02:22.84,Default,,0000,0000,0000,,However, instead of remembering\Nthat you've seen it at your grandmother's,
Dialogue: 0,0:02:22.86,0:02:24.83,Default,,0000,0000,0000,,your brain has summoned up the old memory
Dialogue: 0,0:02:24.85,0:02:26.45,Default,,0000,0000,0000,,without identifying it.
Dialogue: 0,0:02:26.47,0:02:29.80,Default,,0000,0000,0000,,This leaves you stuck with familiarity,\Nbut no recollection.
Dialogue: 0,0:02:29.82,0:02:31.97,Default,,0000,0000,0000,,Although you've never been\Nin this restaurant,
Dialogue: 0,0:02:31.99,0:02:35.31,Default,,0000,0000,0000,,you've seen that tablecloth\Nbut are just failing to identify it.
Dialogue: 0,0:02:35.33,0:02:36.60,Default,,0000,0000,0000,,Now, look at this fork.
Dialogue: 0,0:02:36.62,0:02:38.02,Default,,0000,0000,0000,,Are you paying attention?
Dialogue: 0,0:02:38.04,0:02:40.14,Default,,0000,0000,0000,,Our last theory is divided attention,
Dialogue: 0,0:02:40.17,0:02:41.99,Default,,0000,0000,0000,,and it states that déjà vu occurs
Dialogue: 0,0:02:42.01,0:02:44.43,Default,,0000,0000,0000,,when our brain subliminally\Ntakes in an environment
Dialogue: 0,0:02:44.45,0:02:47.18,Default,,0000,0000,0000,,while we're distracted\Nby one particular object.
Dialogue: 0,0:02:47.20,0:02:48.49,Default,,0000,0000,0000,,When our attention returns,
Dialogue: 0,0:02:48.51,0:02:50.32,Default,,0000,0000,0000,,we feel as if we've been here before.
Dialogue: 0,0:02:50.35,0:02:52.45,Default,,0000,0000,0000,,For example, just now\Nyou focused on the fork
Dialogue: 0,0:02:52.48,0:02:55.11,Default,,0000,0000,0000,,and didn't observe the tablecloth\Nor the falling waiter.
Dialogue: 0,0:02:55.14,0:02:57.43,Default,,0000,0000,0000,,Although your brain has been\Nrecording everything
Dialogue: 0,0:02:57.45,0:02:58.69,Default,,0000,0000,0000,,in your peripheral vision,
Dialogue: 0,0:02:58.72,0:03:00.93,Default,,0000,0000,0000,,it's been doing so\Nbelow conscious awareness.
Dialogue: 0,0:03:00.96,0:03:03.30,Default,,0000,0000,0000,,When you finally pull yourself\Naway from the fork,
Dialogue: 0,0:03:03.32,0:03:05.71,Default,,0000,0000,0000,,you think you've been here before\Nbecause you have,
Dialogue: 0,0:03:05.73,0:03:07.36,Default,,0000,0000,0000,,you just weren't paying attention.
Dialogue: 0,0:03:07.38,0:03:10.73,Default,,0000,0000,0000,,While all three of these theories\Nshare the common features of déjà vu,
Dialogue: 0,0:03:10.75,0:03:13.00,Default,,0000,0000,0000,,none of them propose to be\Nthe conclusive source
Dialogue: 0,0:03:13.03,0:03:14.14,Default,,0000,0000,0000,,of the phenomenon.
Dialogue: 0,0:03:14.17,0:03:16.55,Default,,0000,0000,0000,,Still, while we wait\Nfor researchers and inventers
Dialogue: 0,0:03:16.57,0:03:19.35,Default,,0000,0000,0000,,to come up with new ways\Nto capture this fleeting moment,
Dialogue: 0,0:03:19.37,0:03:21.40,Default,,0000,0000,0000,,we can study the moment ourselves.
Dialogue: 0,0:03:21.100,0:03:25.48,Default,,0000,0000,0000,,After all, most studies of déjà vu\Nare based on first-hand accounts,
Dialogue: 0,0:03:25.50,0:03:27.32,Default,,0000,0000,0000,,so why can't one be yours?
Dialogue: 0,0:03:27.34,0:03:30.70,Default,,0000,0000,0000,,The next time you get déjà vu,\Ntake a moment to think about it.
Dialogue: 0,0:03:30.73,0:03:32.11,Default,,0000,0000,0000,,Have you been distracted?
Dialogue: 0,0:03:32.14,0:03:34.24,Default,,0000,0000,0000,,Is there a familiar object somewhere?
Dialogue: 0,0:03:34.26,0:03:36.31,Default,,0000,0000,0000,,Is your brain just acting slow?
Dialogue: 0,0:03:36.34,0:03:38.60,Default,,0000,0000,0000,,Or is it something else?
