Botany in a Day Botany in a Day Botany in a Day: The Patterns Method of Plant Identification is a book by Thomas J. Elpel published by HOPS Press, LLC. The book emphasizes family characteristics for plant identification. Related plants typically have similar floral features and often similar uses. For example, plants of the mustard family (Brassicaceae) have four petals with six stamens (4 tall, 2 short), and most or all of the 3,200 species are considered edible. The book is used as a text at universities, high schools, and herbal schools across North America. It is also recommended as a resource for the
Calyx of Held MNTB neurons to reach the SOC approximately 0.2 ms following the initial cochlear excitation. This ~0.2 second time measurement is important for comparing the contralateral (opposite side) and ipsilateral (same side) stimulation necessary in sound localization in the horizontal plane, and is key in distinguishing the location of low frequency sounds. For every principal neuron there is one calyx, and for most GBC axons there is only a single calyx, although there are exceptions to this pairing. This in general creates a one-to-one ratio between GBCs, the calyces of Held, and the principal neurons. The calyx of Held encompasses the
