Calyx-Krater by the artist called the Painter of the Berlin Hydria depicting an Amazonomachy Calyx-Krater by the artist called the Painter of the Berlin Hydria depicting an Amazonomachy The calyx-krater by the artist called the "Painter of the Berlin Hydria depicting an Amazonomachy" is an ancient Greek painted vase in the red figure style, now in the Metropolitan Museum of Art, New York. It is a krater, a bowl made for mixing wine and water, and specifically a calyx-krater, where the bowl resembles the calyx of a flower. Vessels such as these were often used at a symposion, which was an elite party for drinking. Warfare depicted in Greek art was often not representative
Calyx of Held causes an action potential to be triggered on the postsynaptic side – further encouraged by low internal sodium of the principal neurons. In the mature calyx, the AMPA receptors are concentrated on the principal neuron as to localize the transmission for greater action potential probability. Also note, the NMDA-type glutamate receptors contributions decrease after the onset of hearing. The mechanism behind synaptic vesicle endocytosis changes as the calyx becomes more mature. Calmodulin and calcineurin in their active form are required for vesicle endocytosis in an immature calyx; however, in the mature calyx neither calmodulin nor calcineurin are necessary. Rather, the
