I've been a night owl for as long as I can remember, and the one thing I know is that my sleep preferences do not match up well with Corporate America working hours.  This mismatch can be life impacting.  For this piece of research to have a practical application for me, I'd like to know how well a night owl can adjust her sleep schedule (either with light therapy, or medication) to match the "real" world while still maintaining her mental acuity and focus.  Or does nature revolt if you try to turn a night owl into more of an early bird?

Although it sounds interesting, can't help thinking that it is like comparing apples and oranges or cats and dogs or birds and owls rather. They are two different species with different potential, capabilities, behavier, and many others.. you name it. Owl may have longer concentration or whatever difference since it is owl not because of its sleeping behavier.. It seems dangerous to draw any conclusion from such "scientific" or non scientific experiment.

Very interesting.  No mention of the early birds' and the night owls' age.   I would think age would be a part of the brain regions response, due to aging..

So glad to read something like this.  Early birds (I think I'm a hybrid- HI-Bird) do tend to have a morally superior additude.  They think if you sleep late you're a slacker.  I wake up early most days and feel like I am more creative and focused early, but I often stay up late and I feel pretty clear headed too.
