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
Kamay Botany Bay National Park part of the first landing of the "Endeavour" in Australia. Banks and Solander collected a large number of iconic Australian plant species, including some that later became type-specimens which have important scientific and research value. Botany Bay lies within a small tectonic depression known as the Botany Basin which in turn is situated within the larger Sydney Basin comprising modified sedimentary deposits laid down about 270 million years ago during the Permian period. The northern and southern headlands featuring Hawkesbury sandstone cliffs which were formed during the Triassic period, between 200 and 250 million years ago. On the Kurnell peninsular,
