Upregulation of purinergic P2Y receptor-mediated calcium responses in glial cells during experimental detachment of the rabbit retina.

abstract：:Neurons of the medial septum-nucleus of the diagonal band of Broca (vertical limb) area were identified as septo-hippocampal neurons by antidromic electrical activation in anesthetized rats. A large majority of these presumably cholinergic neurons could be excited by the iontophoretic application of acetylcholine or c...

abstract：:Melatonin is the principle hormonal product of the pineal gland. It is secreted with a robust daily rhythm, peaking near the middle of the night. During the daytime, concentrations remain very low, as exposure to light robustly suppresses its secretion. The regulation of melatonin by light is well-characterized, but a...
