As to your main question, I imagine the Paul Allan Brain Atlas has what you're looking for. In 3D even.
Human Brain Map
D1 Receptor
D2 Receptor
Also comes in mouse flavored.
Offhand, I cannot be of assistance for the second question.

There's two phases of a menstrual cycle, before ovulation known as the follicular phase and after ovulation known as the luteal phase. The second phase is not very variable, it's the same length almost always as it is governed by how long the corpus luteum (remnants of the follicles after the ovum bursts out) survives. The first part is variable and is what ...

There isn't a central/master website that I'm aware of, as it's still an area of active research. I did a bit of work in the field about 10 years ago, and at that point we were still working out the circadian rhythms in the yeast mating cycle.
Since then, the field been enumerating more and more involved processes: mRNA expression, mRNA degradation, micro ...

From Kalsbeek et al 1999 Neuroscience (link 1, link 2)
"retina-mediated photic activation of suprachiasmatic nucleus neurons
induces the release of GABA from efferent suprachiasmatic nucleus
nerve terminals, resulting in an inhibition of melatonin release by
the pineal gland."
So it appears that GABA is key. When the retina is stimulated by light ...

Take a look at this (especially page 938): Coordination of circadian timing in mammals by Steven M. Reppert & David R. Weaver Nature 418, 935-941 (29 August 2002) | doi:10.1038/nature00965
Sodium-dependent action potentials provide the primary means by which
the SCN transmit circadian outputs to other brain areas and are
essential to its role as ...
