Hello.

00:00:02.820 --> 00:00:06.478 align:middle line:84%
Welcome to week two of
the Pupillometry MOOC.

00:00:06.478 --> 00:00:08.520 align:middle line:84%
I'm Connor Spiech, and
I'm a researcher at RITMO,

00:00:08.520 --> 00:00:11.370 align:middle line:84%
investigating the
pupillometry of groove.

00:00:11.370 --> 00:00:12.250 align:middle line:90%
[CHAIR SQUEAKS]

00:00:12.250 --> 00:00:12.750 align:middle line:90%
Oh.

00:00:12.750 --> 00:00:14.678 align:middle line:90%
That was awful.

00:00:14.678 --> 00:00:16.470 align:middle line:84%
So Bruno, can you tell
me a little bit more

00:00:16.470 --> 00:00:18.090 align:middle line:90%
about how the eye is organised?

00:00:18.090 --> 00:00:19.990 align:middle line:84%
It seems like a really
complicated organ.

00:00:19.990 --> 00:00:20.490 align:middle line:90%
Oh.

00:00:20.490 --> 00:00:21.570 align:middle line:90%
Oh, yes, it is.

00:00:21.570 --> 00:00:26.610 align:middle line:84%
You see, the eye is
already part of the brain.

00:00:26.610 --> 00:00:29.760 align:middle line:84%
As a matter of fact, it's the
only visible part of the brain,

00:00:29.760 --> 00:00:34.920 align:middle line:84%
as a researcher in pupillometry
already said in the 1970s.

00:00:34.920 --> 00:00:35.430 align:middle line:90%
Really?

00:00:35.430 --> 00:00:37.200 align:middle line:90%
So how's that work?

00:00:37.200 --> 00:00:43.380 align:middle line:84%
Well, you know, the
retina is a complex layer

00:00:43.380 --> 00:00:47.040 align:middle line:84%
and a neural network
that is already not

00:00:47.040 --> 00:00:50.730 align:middle line:84%
only receiving
light information,

00:00:50.730 --> 00:00:55.290 align:middle line:84%
but elaborating it,
making processing already

00:00:55.290 --> 00:00:56.430 align:middle line:90%
within the eye.

00:00:56.430 --> 00:00:57.240 align:middle line:90%
OK.

00:00:57.240 --> 00:01:00.450 align:middle line:84%
So where does the visual
perception part of things

00:01:00.450 --> 00:01:01.920 align:middle line:90%
start?

00:01:01.920 --> 00:01:03.960 align:middle line:90%
Well, it starts with the eye.

00:01:03.960 --> 00:01:08.940 align:middle line:84%
But if you're thinking about
our conscious perception

00:01:08.940 --> 00:01:13.710 align:middle line:84%
of the outside world,
well, the processing

00:01:13.710 --> 00:01:16.440 align:middle line:84%
that initiates in
the eye needs to go

00:01:16.440 --> 00:01:21.300 align:middle line:84%
through the brain in
different stages and layers

00:01:21.300 --> 00:01:25.770 align:middle line:84%
and reach the cortex in order
to construct the world as we

00:01:25.770 --> 00:01:27.900 align:middle line:90%
see it and we know it.

00:01:27.900 --> 00:01:30.050 align:middle line:90%
Interesting.

00:01:30.050 --> 00:01:40.000 align:middle line:90%
