But I have to ask - I can understand removing a friut fly's brain, but what studies can you do based on that?
You can use various techniques to visualize e.g. three-dimensional gene expression in the brain:

That link is fairly old, but shows the basics.

So I just PayPal you $33 and will get the ram in the mail? Hell yeah I'll do that. It'll take me years to find the time to install them, but at least I know I can do it any time
