The first important work
devoted to microscopical observation, and
showed what the microscope could mean for naturalist. He uses this book to describe the microscopic units that made up the structure of a slice of cork and coined the term "cells" or "pores" to refer to these units. -
The conclusions of Schleiden considered to represent the official formulation of ‘cell theory’ and their names are
almost as closely linked to cell theory as are
those of Watson and Crick with the structure of DNA. This is important because it tells us who studied that plants were made up of cells. -
The Scottish botanist Robert Brown was the first to recognize the nucleus (a term that he introduced) as an essential
constituent of living cells. -
Cells were not seen as undifferentiated structures. Some cellular components, such as the nucleus, had been visualized, and the
occurrence of these structures in cells of different tissues and organisms hinted at the possibility that cells of similar organization
might underlie all living matter. This is important because this is the main idea of the timeline. -
Ironically, it was by using Golgi’s black
reaction that the Spanish neuroanatomist
Santiago Ramón y Cajal became
the main supporter and indefatigable champion of the neuron theory. His neuroanatomical investigations contributed to the
foundations of the basic concepts of modern
neuroscience. -
A book by Karl Deiters published posthumously in 1865, contains
beautiful descriptions and drawings of nerve cells studied by using histological methods and microdissections made with thin needles under the microscope. This book helped people learn about the nerve cells and study them the same way this author did. -
The introduction of the oil immersion lens in 1870, the development of the microtome technique and the use of new fixing methods and dyes greatly improved microscopy. This is important because it helped improve science. -
The most important breakthrough in neurocytology and neuroanatomy. Which he announced to a friend with
these few words, “I am delighted that I have between neurons. When the nervous system was also found to be made up of independent
units, cell theory obtained its final triumph. -
This process was observed in plants, providing further evidence of the deep unity of the living world. This is important because it's still a term we use today and it had an impact on modern day science. -
Walter introduces the term to indicate independent nerve cells. Thereafter, cell theory as applied to the nervous system became
known as the ‘neuron theory’. This is important because this tells us who introduced the term and why.
