Achlys (plant) these plants include vanilla leaf (sometimes written as vanilla-leaf or vanillaleaf, depending on the taxonomist or flora), deer's foot and sweet after death, referring to the vanilla scent of its crushed leaves. The Plant List recognizes two species, with "A. californica" regarded as a subspecies of "A. triphylla" "Achlys triphylla", known in western North America as vanillaleaf, is an erect perennial plant that sprouts from a creeping rhizome. Leaves are long-petioled and palmately divided into three leaflets. Flowers are small and lack sepals and petals, but instead have long showy white stamens that form single erect spikes. The leaflets give
Calyx of Held sensitivity. Both low-threshold K channels and high-threshold delayed rectifier-type K channels are present in presynaptic neurons. There are four low-threshold K channels present: K1.1, K1.2, K1.3, and K7.5. K1.1 and K1.2 are located in the transition zone between the axon and the terminal, while K1.3 K7.5 are located in the calyx. There is a calcium activated potassium channel expressed in the calyx, however this type of channel does not contribute to neurotransmitter release. Within the span of one week, mice subjects (P7 to P14) showed that the density of the K1 and K3 low threshold channels increases, which in turn
