Calyx of Held nervous system has allowed for direct research within a mammalian model and the large size increases the ease of electrophysiological recording. For these reasons it has been popular in understanding transmitter release. Specifically, the calyx of Held is used because of: Calyx of Held The Calyx of Held is a particularly large synapse in the mammalian auditory central nervous system, so named by Hans Held in his 1893 article "Die centrale Gehörleitung" because of its resemblance to the calyx of a flower. Globular bushy cells in the anteroventral cochlear nucleus (AVCN) send axons to the contralateral medial nucleus of the
Plant physiology plants in a water solution rather than soil, which has become a standard technique in biological research, teaching lab exercises, crop production and as a hobby. One of the leading journals in the field is "Plant Physiology", started in 1926. All its back issues are available online for free. Many other journals often carry plant physiology articles, including "Physiologia Plantarum", "Journal of Experimental Botany", "American Journal of Botany", "Annals of Botany", "Journal of Plant Nutrition" and "Proceedings of the National Academy of Sciences." In horticulture and agriculture along with food science, plant physiology is an important topic relating to fruits,
