Find the retinal receptive field for the cell you are recording from and determine its location and type.

INSTRUCTIONS

Record from a ganglion cell: To select and record from a ganglion cell, drag the electrode and place it on the retina or optic nerve.
Change stimulus: Click and drag the spot of light on the screen at the right until you see a change in action potential response. An increase or decrease in the response indicates you have found part of the receptive field of your selected ganglion cell.
Map receptive field: Click one of the buttons under Mapping Tools to mark the activity level where the spot of light is. Continue moving the spot and mapping the activity until you have created an image of an on-center or off-center receptive field on the screen. Click Show Receptive Field to confirm your map.
