Ears that see by Sasha Brady https://padlet.com/bradysashaptech/ixnd9xu70jng By Gray and Sasha en-us 2018-05-01 12:45:40 UTC 2018-05-14 12:40:52 UTC hello@padlet.com The lives of the blind years ago bradysashaptech https://padlet.com/bradysashaptech/ixnd9xu70jng/wish/256826728 -In early great civilizations, blind babies were abandoned and left to die
-Some blind men were sold into galley slavery and some blind women were sold into prostitution.
--By the middle ages, civilized societies (particularly in Europe) began to operate in the belief that it was an obligation of society itself to care for the "less fortunate," including the blind. ]]> 2018-05-01 12:59:31 UTC https://padlet.com/bradysashaptech/ixnd9xu70jng/wish/256826728 Improvements for the blind bradysashaptech https://padlet.com/bradysashaptech/ixnd9xu70jng/wish/256828472 -The first school for the blind was set up in France in 1784
-Louis Braille invented tactile reading and writing system by 1820
-Scientists studied the brains of blind people who've learned to use an augmented reality system that converts images into soundscapes in the early 90's (not widely used)
Augmented reality: A direct or indirect live view of a physical, real-world environment whose elements are "augmented" (made greater) by computer-generated perceptual information.

Cornea- transparent anterior part of the sclera, allows light rays to enter the eye
Choroid- middle layer of the eye
Iris-Pigmented muscular structure that regulates the amount of light entering the eye
Pupil- opening in the center of the eye
Lens- Located behind the pupil, focuses and bends light
Optic nerve- Carries visual impulses from the retina to the brain
Conjunctiva- Mucous membrane lining the eyelids and covering the anterior portion of the sclera

Aqueous humor- Watery liquid that provides nourishment to nearby structures, maintains shape in the anterior part of the eye
Vitreous humor- jelly-like substance found behind the lens
Meibomian glands- Oil glands found in the upper and lower edges of the eyelids that help lubricate the eye
Lacrimal apparatus- Network of glands, ducts, canals, and sacs that produce and drain tears

- Moves into the lens, which bends the light
-Focuses light down to a point on the retina, at the back of the eye. 
-The retina is covered in millions of light-sensitive receptors known as rods and cones. 
-Each receptor contains pigment molecules, which change shape when they are hit by light, triggering an electrical message that travels to the brain via the optic nerve.]]> 2018-05-01 13:13:37 UTC https://padlet.com/bradysashaptech/ixnd9xu70jng/wish/256832126 How does the ear work? bradysashaptech https://padlet.com/bradysashaptech/ixnd9xu70jng/wish/256832803 -Vibrations are picked up and concentrated into the ear canal 
-Bounces off the tympanic membrane and causing the ossicles to increase the vibrations. -They are then sent to the cochlea, which connects to the auditory nerve.  
-The auditory nerve carries the impulses to the temporal lobe, which converts them into sound. ]]> 2018-05-01 13:15:06 UTC https://padlet.com/bradysashaptech/ixnd9xu70jng/wish/256832803 How does the information collected from the eyes and the ears travel to the brain? bradysashaptech https://padlet.com/bradysashaptech/ixnd9xu70jng/wish/256835609 -The senses are not experienced individually
-The brain meshes with our vision and hearing to create our conscious experience of the world. 
-What you see can influence what you hear, and likewise hearing can affect vision.]]> 2018-05-01 13:20:48 UTC https://padlet.com/bradysashaptech/ixnd9xu70jng/wish/256835609 Videos bradysashaptech https://padlet.com/bradysashaptech/ixnd9xu70jng/wish/257212387 How do blind people see the world?
