Brain Animation

I would like a high quality animation involving ion channels on neurons. The animation should have two parts. 1. Showing the opening and closing of an ion channel sitting in a membrane of cell with ions flowing into an out of the cell. 2. Showing a neuron as ion channels fly in and insert into the membrane completely covering the entire surface. many different ion channels (i.e. in different colors) should be used. You can check out google images for what an ion channel and neurons looks like.
