Leptotes (plant) species that have more rounded flowers with petals and sepals that are wide open and flatter. The leaves are shorter wrinkly leaves, generally very dark green or purple colored. The species of this group often have only one or two flowers on each inflorescence. Four of them are very similar and sometimes difficult to distinguish. Leptotes (plant) Leptotes, abbreviated Lpt in horticultural trade, is a genus of orchids formed by nine small species that grow in the dry jungles of south and southeast Brazil, and also in Paraguay or Argentina. They are small epiphytic plants of caespitose growth that sometimes
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
