Designing an electronic system to record eye movements

hi everybody
first i'm sorryto post this her
but i'm fully hope to find people have a past experinces about medical electronics
i have a graduation project and the course is given for the first time
the title of the project is designing a system to measure and record eyes movements
the most important block is the main and the primary amplifiers






thanks every body in advanced

thank you blueroomelectronics
but i think that i need the skematic circuit and components of such systems

It's a video camera (probably a webcam) and some specialized software. Since it's a graduation project aren't you the one supposed to be demonstrating your ability?
