BODY LANGUAGE

I am really honoured and delighted to be able to give this annual lecture. You can tell from the title - 'Light, time and health: biology to architecture' - that when I gave it, I clearly wasn't sure what I was going to be talking about, because that basically covers everything.But what I'd like to hone in on are the following topics. What I thought might be useful to kick off is to talk about the diversity of the light environment in which we live, and to talk a bit about evolution and give a very brief outline of the image-forming visual system, the classical rod cone visual system. I then want to contrast it with this other photoreceptor system that we've discovered in the eye: the non-image forming light detector system.
