Cajal's Neuronal Forest
Cajal’s Neuronal Forest: Science and Art continues the tradition set forth in the 2009 publication Cajal’s Butterflies of the Soul: Science and Art. This new compilation contains a vastly large collection of beautiful figures produced throughout the nineteenth century and the beginning of the twentieth century. These images continue to represent and illustrate characteristic examples of the early days of research in neuroscience. Most scientific figures presented by the neuroanatomists of the time were their own drawings; microphotography was not yet a well-developed technique. Therefore, a successful neuroanatomist required a combination of artistic talent and an ability to interpret microscopic images effectively. The problem was that these illustrations were not necessarily free of technical errors and they may have been subject to the scientists’ own interpretations. Indeed, in some cases, these drawings were considered to be basically artistic interpretations rather than accurate copies of the histological preparations. Furthermore, there are many examples showing that even using the same microscopes and the same techniques, scientists “see” differently through the microscope. As a result, this period of scientific “art” and skepticism represents a fascinating page in the history of neuroscience as it provided the basis of our current understanding of the anatomy of the nervous system.
