Question: Were Caton and Beck both from Poland? Passage:From the bioelectricity of nerves, Marxow turned his attention, from 1876 on, to the global electrical activity of the cerebral hemispheres. Neuroanatomists had already determined at the time that its nervous tissue was also composed of cells (the neurons), with their bodies mainly located in the gray matter, and filamentary prolongations, the dendrites and the axons. Thus, it was only natural to assume that they would also display electrical activity. This important discovery, however, had not been made until that time, because many desynchronized electrical potentials with different polarities produce a cumulative global potential which is actually very small and difficult to detect with the sensitivity range of the measuring devices available at the time. Despite this, Marxow was able to prove for the first time that the peripheral stimulation of sensory organs, such as vision and hearing were able to provoke event-related small electrical potential swings on the surface of the cerebral cortex which was related to the projection of those senses. Strangely, however, Marxow did not publish his results, choosing instead to deposit them in a bank safe, with instructions to reveal them in 1883 only. Meanwhile, the first publications about what was later to be called the electroencephalogram came to light, independently demonstrated by Richard Caton (18421926), in Great Britain, and Adolf Beck (18631942) in Poland, both using laboratory animals.
