Via the excellent Biosingularity I found this great article about the visual process of the blowfly.The article describes a relationship that exists between distinct nerve cells in the signal processing path in the fly’s brain. Two cells, one in each eye, have a direct relationship which helps the organism merge and respond to visual information.

That’s pretty excellent. To figure it out, they had to individually dye fly neurons and then bake them with lasers. Which sounds difficult and tedious. Hurray for Science!

The language is even better than the science

It is important for the analysis of flow fields that the movement information from both eyes is merged so that the whole flow field can be assessed.

I think that’s my new motto.
