Persistence In Perfusion

This post, from January 25, 2006, describes part of the Doctoral work of my lab-buddy Chris.

This is a summary of my 1999 paper, following in the footsteps of the work I described here two days ago. The work described in that earlier post was done surprisingly quickly – in about a year – so I decided to do some more for my Masters Thesis. The obvious next thing to do…

How eyes talk to each other?

One of the important questions in the study of circadian organization is the way multiple clocks in the body communicate with each other in order to produce unified rhythmic output.

Quail: How many clocks?

One of the assumptions in the study of circadian organization is that, at the level of molecules and cells, all vertebrate (and perhaps all animal) clocks work in roughly the same way. The diversity of circadian properties is understood to be a higher-level property of interacting multicellular and multi-organ circadian systems: how the clocks receive…

This April 09, 2006 post places another paper of ours (Reference #17) within a broader context of physiology, behavior, ecology and evolution. The paper was a result of a “communal” experiment in the lab, i.e., it was not included in anyone’s Thesis. My advisor designed it and started the experiment with the first couple of…

This post (written on August 13, 2005) describes the basic theory behind photoperiodism and some experimental protocols developed to test the theory.

This post from March 27, 2006 starts with some of my old research and poses a new hypothesis.

Clock Tutorial #15: Seasonality

This post (click on the icon) was originally written on May 07, 2005, introducing the topic of neuroendocrine control of seasonal changes in physiology and behavior.

Since this is another one of the recurring themes on my blog, I decided to republish all of my old posts on the topic together under the fold. Since my move here to the new blog, I have continued to write about this, e.g., in the following posts: Preserving species diversity – long-term thinking Hot…

This is the sixth post in a series about mechanism of entrainment, running all day today on this blog. In order to understand the content of this post, you need to read the previous five installments. The original of this post was first written on April 12, 2005.
