More self-advertisement / something for the especially bored:
A little history of neuroscience (ish) essay, called Biophysikalisches Doppelleben, 1939–1946. Oder: Räume der Lange-weile [meaning, in a not so elegant translation, Biophysical Double-lives, 1939-1945. Or, Spaces of Boredom] - of use only to those who know some German, I'm afraid. (Mostly due the fact that it deploys some very cleverly thought-out puns on the word "Langeweile" which only work in German really).
