how could i label retinal axons?

Here's a great diagram: http://www.science.mcmaster.ca/psychology/psych2e03km/psych2e03-2005/lecture3/psych.2e03.lecture3.html

i don't think they know for sure. they probably just study optic nerve to see the complexity of the nerve. lets say it was extremely complex mabye they see colors that are warm colors or cool colors only.

Your eye works in a similar way to a camera - light passes through the lens of your eye and is 'recorded' on the back of your eye (the retina).\n\nThe retina is like a movie screen which shows the picture you are seeing. The retina has two lots of cells called 'rods' and 'cones' [because that is what they look like.] Rods can 'see' black and white.  Cones can 'see' colors. They turn the picture into an electrical message for the brain.

I think you will find what you need here:\n\nhttp://faculty.washington.edu/chudler/introb.html\n\nIt is a good but simple site on neuroscience.\n\nThere was an identical question in Yahoo Answers since yours; I answered that in the same way.  Check it out for other help.

The Dendrites receive the information transmitted by action potentials from other neurons.  The Axon conducts an action potential to the synapse to pass on to other neurons.  In other words,  Dendrites receive information and the Axon sends information.  \n\nA neuron has many dendrites but only one axon.\n\nHope this helps!

Is is a detached retina? this is cas posterior is like "back"

I dont know much but i would like to help you....u can use lenses...and a liquid similar to the vitreous humor.\nBut its really interesting that u r trying to create a Working model of human eye. Good luck.

Most cells are opaque, or colorless.  If you want a good view, you must color it.

For one, cameras today can't produce the resolution that a human eye can produce.\n\nThey are working on artificial eyes and radar, and I think a Retinal Transplant might help you. Talk to your doctor about if you are a possible candidate.

Neuronal activity is very complex, while influx of one molecule into the hilloc causes its depolarisation in one neuron it leads to hyperpolarisation in another.  With sufficient depolarisation and build up of Excitation K+ and Na+ activity beggins.  for every 2K+ brought into the cell 3Na+ are emitted from the cell.  This causes a cascade down the cell due to comple intracellular events of the depolarization being propagated down the axon.  This is electrical activity and so can be detected with electrodes.  There are many different types of proteins some of which are voltage sensitive along the length of the axon.  The local change in voltage activates these other channels leading to further depolarization and propogation moving along on.  This allows the depolarization to effectivley jump from one node of ranvier to the next (none insulated parts of neuron).  Talking of insulation, the mylin sheeth is made of schwan cells which promots signal propogation much like plastic covering copper.\n\nThe internal signals are very complex and would require a diagram, but involve Gproteins and Ca++.......

chloroplasts, flagella, contractile vacuoles and the eye spot for starters.

The word you are looking for is Phosphene.\n\nPhosphenes are the light sensation you experience often from pressure/stimulus on your retina.

At the back of your eye there is a collection of cells called the retina that are sensitive to light.  They cover the majority of the back half of the eye, except for an area called the "blind spot".  This is the point at which all the nerves that carry information from the retina out of the eyes and towards the brain.  Because this area is dense with nerves there are no photosensitive cells.\n\nIt is important to note that you cannot sense your blind spot directly, ie. you do no have a black hole in the field of vision.  This is for two reasons.  First, the area in your blind spot for one eye is clearly visible by your other eye.  This way the blind spots never overlap as long as both your eyes are open.  Second, after the nerves leave the eyes they enter a part of your brain that processes the information.  At this point your brain "fills" in the blind spot so it is not noticeable to you!
