 I'm David Sarrick from the University of Edinburgh and what I work on is generally at the moment is development and how the connections grow from the eye to the brain. Now, one of the things that is done in this work is that tracer is injected into the brain of the developing mouse and then it transports back to the eye and then we have to dissect out the eyes in order to find out where the tracer has gone. And the problem is when you're doing that, what you do is you take an eye and you flatten it out and that's very good for analysing into the microscope. But the problem is that you don't know where the tracer was that you originally put in, that went in. You don't actually know where it was on the intact eye. So what I'm talking about here is a work done with collaboration with Daniel Lingholm and David Orshawn, Ian Thompson, Daniel and Ian are in Kings, is to try and reconstruct this. And what we do is we have a sort of virtual method of reconstruction where we mark up where the incisions were and then the algorithm stitches them together and then morphs them onto an eye shaped sphere and gradually refines them up and then you can actually figure out, do projections of where things were on the actual sphere. And one really cool thing is that then we can project, we can imagine what would happen if we projected the eye into visual space. And so here you can see we've put marker into the left and right LGN and then you can see that we've projected the ipsolactral marker back onto the visual space here and when you get the axis of the eye in the right direction then you end up with a nice matching up between the edges of the ipsolactral collection. So the other advantage of this method is that it allows you to compare eyes from different animals which is really important when we're looking over a developmental time course and we're trying to put together data from different animals.
