Flowering plant serve to protect the sporophylls and to form an envelope attractive to pollinators. The individual members of these surrounding structures are known as sepals and petals (or tepals in flowers such as "Magnolia" where sepals and petals are not distinguishable from each other). The outer series (calyx of sepals) is usually green and leaf-like, and functions to protect the rest of the flower, especially the bud. The inner series (corolla of petals) is, in general, white or brightly colored, and is more delicate in structure. It functions to attract insect or bird pollinators. Attraction is effected by color, scent, and
Calyx of Held inhibitory effects. As a result of its role in stimulating the principal neurons, the primary function of the calyx of Held is to allow differentiation between temporal activation of the cochlear hair cells that are important in sound localization (interaural level detection). Interaural level detection is possible through the calyx system due to the large relative size of the GBCs, the calyx of Held, and the principal neurons. The neurons in the Lateral Superior Olive are especially important in discerning these interaural level changes. The large diameter size of the bushy cell axons allows the inhibitory signal produced by the
