Dialogue: 0,0:00:09.60,0:00:14.25,Default,,0000,0000,0000,,[Narrator] Unlike Graham,\NPeggy Palmer has normal vision.
Dialogue: 0,0:00:14.25,0:00:17.50,Default,,0000,0000,0000,,She should be able to copy this star easily.
Dialogue: 0,0:00:17.50,0:00:19.90,Default,,0000,0000,0000,,[Peggy] "I'll never get this star\NI'm hopeless at this."
Dialogue: 0,0:00:19.90,0:00:22.99,Default,,0000,0000,0000,,[Narrator] But something odd is happening.
Dialogue: 0,0:00:22.99,0:00:27.55,Default,,0000,0000,0000,,One whole side of the star is missing.
Dialogue: 0,0:00:27.55,0:00:31.44,Default,,0000,0000,0000,,Peggy has a condition called \Nvisual neglect.
Dialogue: 0,0:00:31.44,0:00:33.91,Default,,0000,0000,0000,,Although her eyesight is fine, \N
Dialogue: 0,0:00:33.91,0:00:39.05,Default,,0000,0000,0000,,half of her visual world\Nno longer seems to matter.
Dialogue: 0,0:00:39.05,0:00:44.22,Default,,0000,0000,0000,,Ten years ago, Peggy suffered a stroke\Nin the parietal lobes of her brain.
Dialogue: 0,0:00:44.22,0:00:48.32,Default,,0000,0000,0000,,[V.S. Ramachandran]\N"The parietal lobes are concerned mainly
Dialogue: 0,0:00:48.32,0:00:50.60,Default,,0000,0000,0000,,with creating a three-dimensional representation
Dialogue: 0,0:00:50.60,0:00:55.42,Default,,0000,0000,0000,,of the spatial layout of the world \Nallowing a person to walk around
Dialogue: 0,0:00:55.42,0:01:00.71,Default,,0000,0000,0000,,to navigate, to avoid bumping into things.
Dialogue: 0,0:01:00.71,0:01:02.66,Default,,0000,0000,0000,,When the right side is damaged
Dialogue: 0,0:01:02.66,0:01:07.74,Default,,0000,0000,0000,,the patient is unable to\Ndeal with the left side of the world.
Dialogue: 0,0:01:07.74,0:01:11.64,Default,,0000,0000,0000,,[Narrator] This condition has fascinated\Nneurologists for more than a century
Dialogue: 0,0:01:11.64,0:01:17.28,Default,,0000,0000,0000,,because it reveals not only how the\Nbrain shapes the way we perceive space in the present
Dialogue: 0,0:01:17.28,0:01:22.30,Default,,0000,0000,0000,,it even determines the spatial look our memories.
Dialogue: 0,0:01:22.30,0:01:27.61,Default,,0000,0000,0000,,This became apparent when Peggy was asked\Nto draw a daisy from memory.
Dialogue: 0,0:01:28.48,0:01:32.62,Default,,0000,0000,0000,,"Alright, a daisy it shall be"
Dialogue: 0,0:01:32.62,0:01:39.12,Default,,0000,0000,0000,,[Narrator] For neuropsychologist Peter Halligan\NPeggy's drawings reveal exactly what's gone wrong.
Dialogue: 0,0:01:39.12,0:01:42.11,Default,,0000,0000,0000,,[Peter] It is like a radar system whereby
Dialogue: 0,0:01:42.11,0:01:47.18,Default,,0000,0000,0000,,the actual radar system on the left hand\Nside is no longer working well.
Dialogue: 0,0:01:48.52,0:01:50.74,Default,,0000,0000,0000,,If someone comes into my left hand side now
Dialogue: 0,0:01:50.74,0:01:54.62,Default,,0000,0000,0000,,or I hear a sound my eyes will immediately\Nmove to left hand side
Dialogue: 0,0:01:54.62,0:01:58.22,Default,,0000,0000,0000,,that makes me, for evolutionary \Npurposes very aware of my environment
Dialogue: 0,0:01:58.22,0:02:01.34,Default,,0000,0000,0000,,because I wasn't aware of those things I\Nwould have accidents
Dialogue: 0,0:02:01.34,0:02:06.03,Default,,0000,0000,0000,,I'd get hurt or I might get eaten by wild\Nanimals and whatever.
Dialogue: 0,0:02:06.03,0:02:09.17,Default,,0000,0000,0000,,Now, in Peggy's case she will not attend\Nto those things
Dialogue: 0,0:02:09.17,0:02:13.40,Default,,0000,0000,0000,,that we would normally be aware of.
Dialogue: 0,0:02:13.40,0:02:16.16,Default,,0000,0000,0000,,[Narrator] Peggy thinks she's drawn her daisies right
Dialogue: 0,0:02:16.16,0:02:19.62,Default,,0000,0000,0000,,until it's pointed out to her.
Dialogue: 0,0:02:19.62,0:02:20.99,Default,,0000,0000,0000,,[Peter] "You've noticed that, have you?"
Dialogue: 0,0:02:20.99,0:02:22.79,Default,,0000,0000,0000,,[Peggy ]"Oh, dear."
Dialogue: 0,0:02:22.79,0:02:26.31,Default,,0000,0000,0000,,[Peter]\N"So what Peggy's drawn for us is several nice daisies
Dialogue: 0,0:02:26.31,0:02:30.11,Default,,0000,0000,0000,,with the left side missing \Nsame this one and this one
Dialogue: 0,0:02:30.11,0:02:33.36,Default,,0000,0000,0000,,look at this one this is a very good example"
Dialogue: 0,0:02:33.36,0:02:36.02,Default,,0000,0000,0000,,[Peggy] "I've done it on all of them"
Dialogue: 0,0:02:37.43,0:02:41.96,Default,,0000,0000,0000,,[V.S. Ramachandran] Which means she's not only\Nneglecting events in the world but when she
Dialogue: 0,0:02:41.96,0:02:47.15,Default,,0000,0000,0000,,conjures up a mental image she's ignoring\Nthe left side of that mental image.
Dialogue: 0,0:02:47.17,0:02:49.35,Default,,0000,0000,0000,,[Peggy]\N"I thought I was going all the way around you see"
Dialogue: 0,0:02:49.35,0:02:53.29,Default,,0000,0000,0000,,[MD] "And the shows you that this is not\Nsimply a sensory problem but
Dialogue: 0,0:02:53.29,0:02:56.44,Default,,0000,0000,0000,,a problem of consciousness"
Dialogue: 0,0:02:56.44,0:03:02.21,Default,,0000,0000,0000,,[Peggy] "It's cause I was so concentrated on\Nthat side takes everything away, you see
Dialogue: 0,0:03:02.21,0:03:07.27,Default,,0000,0000,0000,,It is attention really is taking this taken away this
Dialogue: 0,0:03:07.27,0:03:13.21,Default,,0000,0000,0000,,there must be two attentions somewhere in your\Nbody one side's taking another one away.
Dialogue: 0,0:03:13.21,0:03:15.94,Default,,0000,0000,0000,,I can't make it out at all, very odd"
