Lewandowsky coined the term blood–brain barrier in 1900, referring to the hypothesized semipermeable membrane which separated the human central nervous system from the rest of the body's vasculature, and which prevented the entry of certain compounds from entering the brain when injected into the bloodstream.[4] Two years earlier, researchers Arthur Biedl and R. Kraus had formed a similar hypothesis when low-concentration "bile salts" failed to affect behavior (and thus, in theory, had failed to enter the brain) when injected into the bloodstream of animals.[5]
In 1908, Lewandowsky and Stadelmann published the first report of an individual with calculation impairment due to brain damage (acalculia; the term would later be introduced by Salomon Eberhard Henschen in 1925). The individual had trouble performing calculations on paper and mentally. Further, he had difficulty recognizing arithmetic symbols. The report was key in that it established calculation disorders as separate from language disorders, as the two were formerly associated.[6]
