In these cases, groups of cell bodies or synapses appear as basically similar configurations, which, however, are different in detail from each other. Such abstract patterns of connectivity are of a statistical nature and do not allow, in a given example, for the prediction of the localization or connections of a particular cell. "Wiring diagrams", therefore, can be obtained only from a multitude of individual observations. In contrast, in several sensory organs, concrete patterns occur that con sist of a regular, mosaic-like, and geometric arrangement of similar cell types. The constancy of such a mosaic allows predictions about certain units of the pattern on the basis of only a few exemplary observations. Typical examples are found in the visual system: In the compound eye of insects, each ommatidium contains a definite number of visual cells that are grouped around the optical axis in a hexogonal array (Kirs | | 出版日期 | Book 1978 | | 关键词 | adaptation; cell; electron microscopy; environment; histology; insects; invertebrates; microscopy; morpholog | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-67071-8 | | isbn_softcover | 978-3-540-09013-7 | | isbn_ebook | 978-3-642-67071-8Series ISSN 0301-5556 Series E-ISSN 2192-7065 | | issn_series | 0301-5556 | | copyright | The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer-Verlag GmbH, DE |
