huh......a talking dog......Well since you asked, their are 6 steps: the 1st being light bouncing off what your looking at and that light is then being focused by the lens.
Hey! how do eyes work?
Why would I need a contact lens?
Ha, no the "lens" in this case is the surface of you eye, not a contact lens
Anyway; then that light is then transferred to the retina witch is a bunch of cells the interpret that light into a upside down image
Correct! and then they go to cells called bipolar cells and ganglion cells which basically just help turn that light into neural signals that your brain can read. and then those signals get passed onto the thalamus (located in the optic nerve) and the thalamus is basically the optic nerve's "mail room" because all it does is send the info to were it needs to go. for this example: the visual cortex.
Soooooo.......thalamus = mailman? And visual cortex = my human?
Ehhhhh........I suppose that'll work. After that, your brain will then put together form, depth, color and motion in a process called Parallel processing.
Okay......wait.......what's step 6?
Perception/recognition! Your brain takes what it sees and figures out what it's seeing based on past experiences.
Why would I need boots?
Also; I heard it's going to rain later so you should probably put some boots on.
......I don't like you.
Because I wouldn't want you to step in a Poodle of rain.
