Interleukin-1beta administered intracerebroventricularly stimulates the release of noradrenaline in the hypothalamic paraventricular nucleus via prostaglandin in the rat

The distribution of birth years for Nobel physicists shows a circaseptennian (about 7-year) periodicity. This observation extends an earlier observation of a circaseptennian pattern in the distribution of birth years for early quantum physicists. In both categories, birth rate tends to maximize in years belonging to the (7n + 4) phase.
