The development of a general theory of frequency encoding in excitable systems by hormonal stimuli allowed the study of intracellular calcium dynamics.
Frequency encoding in excitable systems with application to calcium oscillations.
A scenario emerges from these studies in which calcium ions coordinate the structure of interhemichannel hydrophobic domains.
To counteract the continued inflow of calcium, horizontal cells are endowed with calcium-regulating mechanisms common to other neuronal types.
This small influx of calcium however triggers much larger release from storage sites within the cell, in a highgain process known as calcium-induced calcium release.
However, little is known about which calcium channels are coupled to synaptic exocytosis of glycine, which is primarily released by amacrine cells.
Concentrations of calcium and manganese were positively correlated with each other and with elevation.
Local perinuclear calcium signals associated with mitosis entry in early sea urchin embryos.
