The human cerebral cortex divided into Brodmann areas on the basis of cytoarchitecture. Cytoarchitecture (from Greek κύτος 'cell' and ἀρχιτεκτονική 'architecture'), also known as cytoarchitectonics , is the study of the cellular composition of the central nervous system's tissues under the microscope.
Wilhelm His Sr. (9 July 1831 – 1 May 1904) was a Swiss anatomist and professor who invented the microtome.By treating animal tissue with acids and salts to harden it and then slicing it very thinly with the microtome, scientists were able to further study the organization and function of tissues and cells under a microscope.
Microtonality is the use in music of microtones — intervals smaller than a semitone, also called "microintervals".It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave.
The earliest use I have found so far of the word "microtone" is in 1912 (two years before the earliest citation in the OED), but the article disparages the "widespread use" of the word. This suggests that, amongst ethnomusicologists at least, by 1912 "microtonal" and/or "microtonality" had already been in use for some time.
Porter also contributed to the development of other experimental methods for cell culture and nuclear transplantation. He was also responsible for naming the endoplasmic reticulum , conducting work on the 9 + 2 microtubule structure in the axoneme of cilia , and coining the term " microtrabecular lattice ."
Human culture is not linear, different cultures develop in different directions and at differing paces, and it is not satisfactory or productive to assume cultures develop in the same way. [ 33 ] A further key critique of cultural evolutionism is what is known as "armchair anthropology".
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience. These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development , and continues to develop ...
Roux's investigations were performed mainly on frogs' eggs to research the earliest structures in amphibian development. His goal was to show Darwinian processes at work on the cellular level. Combined with the rediscovery of Gregor Mendel's 1866 paper on heritable elements in peas, these results highlighted the central role of the chromosomes ...
