L2 Optics and the Eye


Videos

Links to videos shown in the lecture:


The Nature of Light

http://archive.org/details/1005_Nature_of_Light_The_09_58_53_15

Start at about 5' 00“ for image formation in cameras.


How the Eye Functions

http://archive.org/details/HowtheEy1941

START VIDEO at about 4' 30” to get good convergence of rays on fovea part.

END about 7' 00“, where convergence section begins (although that's great, too).

PUPIL opening and closing animation: about 10' 00”.


How You See It

http://archive.org/details/HowYouSe1936

1' 15“ Illustration (of a Chevy car) showing that image on retina is upside down, but brain perceives it upright.


Dissection of the Eyeball

http://archive.org/details/0055-0000-7117-0000-0-0000-0000-0

LENS: about 5' 20” start.

About 5' 35“, lens cut out with scissors!


Behind the Lens

http://archive.org/details/Behindth1940

Title shown at beginning of film (about 0' 15”):

“A CAMERA GOES TO COLLEGE”

It's wearing a mortarboard.

Lights from beyond the visual field are not seen.

L4 Retinal Information Processing

Retinal physiology

Tutis Vilis' Physiology of the Senses

Section on the eye, including the retina:

http://www.tutis.ca/Senses/L1Eye/L1eye.swf

(Today we will begin at the section corresponding to the “Fovea” link at bottom.)


Webvision website

Section on horizontal cells and lateral inhibition:

http://webvision.med.utah.edu/book/part-ii-anatomy-and-physiology-of-the-retina/oute-plexiform/

Fig. 9 of this section illustrates horizontal cell dendrites and axons.

Fig. 17 illustrates the tight coupling among a cone and the dendrites of the bipolar and horizontal cells with which it forms synapses.


Another section with nice diagrams illustrating the spatial arrangement of photoreceptors that belong to the same retinal ganglion cell center-surround receptive field:

http://webvision.med.utah.edu/book/part-iii-retinal-circuits/midget-pathways-of-the-primate-retina-underly-resolution/

Especially Fig. 17 of this section.


Sensation and Perception textbook online resources:

http://sites.sinauer.com/wolfe4e/wa02.05.html

Interactive demo of the difference between sensitivity and acuity produced by rod and cone receptive fields.


Contrast and brightness illusions

From Dale Purves' lab website:

http://purveslab.net/see-for-yourself/


From a recently published journal article:

http://journal.frontiersin.org/article/10.3389/fnhum.2014.00999/full

Wonderful animated demos that illustrate the independence of the magno- and parvocellular pathways for motion and color vision.

Discovery of V1 receptive fields

Competition for ocular dominance of V1 neurons during development

http://www.ophthobook.com/videos/pediatric-ophthalmology-video

Section on amblyopia from unbalanced ocular dominance begins at about 13' 20“.
