Visual system and auditory system comparison

I don't know what you're asking here, , since you answered the question yourself, but if you try mapping the visual and auditory pathways out, you will see that they have some similarities and differences. First separately make pathways/diagrams/maps of the two and then compare them side by side. You'll see that they have similar processes and functions, but with different types of cells and organs carrying them out, along with some other major differences in the pathways.

1. Visual
-receptor organs= eyes
-light-->retinal ganglion cells-->lateral geniculate nucleus of thalamus-->primary visual cortex-->visual association areas (V3A-shapes, V5-movements, V2-extrastriate cortex,V3-dynamic shapes, V4-colors and shapes)-->temporal lobe or parietal lobe
-processing = retinotopic at primary visual cortex
-images on retina are maintained in the lateral geniculate nucleus and primary visual cortex=recognition and storage of familiar objects
-damage to lateral geniculate nucleus or primary visual cortex erases association of recognition to that object (like a man who doesn't recognize his wife visually)
-stimulus=light
   -perceive depth, colors, motion, recognition of familiar faces/objects,etc.
   
2. Auditory
-receptor organs= cochlea
-sound waves-->auditory canal-->eardrum--> waves transduced to vibrations-->malleus/incus/stapes bones-->cochlea-->vibrations transduced to electrical information when hair cells fire in the organ of Corti-->cochlear nuclei and inferior colliculus in brainstem-->medial geniculate nucleus of thalamus and primary auditory cortex
-processing= tonotopic at primary auditory cortex
-stimulus=sound
-perceive location/distance, motion, frequency of sound, recognition of familiar sounds/voices

Some more help in the matter:

Okay, that is helpful. Here is a breakdown of what I need to address:

Compare the kind of stimulus the two systems use
Sense organs and general functions (mechanics for processing stimuli and how converted)
Compare transduction in both (receptor potential, and generator potential—give rise to AP)
Sensory field that gives input (visual field, auditory field)
Central sensory pathways and point at which they are sent into the CNS
Stages of pathways—crossed/uncrossed, where do they project, localization
Cortex and secondary areas
Opinion for differences (few sentences)

If you could help me sort these out, that would be the most helpful.
