What to do next?<br />

• Watch the axons as they encounter Ephrin ligand<br />

• Purify proteins from different regions of the tectum.<br />

• Identify proteins present<br />

• Test the proteins to see if they act as guidance<br />

molecules<br />

• Discovered the Ephrin receptor and ligand—work through<br />

contact-mediated guidance (haptotaxis)<br />

• Ephrin Receptor was found in different concentrations<br />

across the retina, and the ligand in different<br />

concentrations across the tectum!
