Abstract

Direct observation of the pial vessels has been carried out for over 100 years.^*A window was used by Ravina²⁰in 1811. He inserted a short cylinder of wood into a trephine hole in a dog's skull. The top of the cylinder was closed by a watch glass cemented in situ. Donders,⁶in 1859, devised an airtight window and made the observation that when the nose and mouth of an animal were obstructed for as short a time as 10 seconds, dilatation of many small vessels became evident. Many other experimentalists used this method of study of the pial circulation. Thus, skull windows as a means of investigation of brain circulation were carried out by Berlin,²in 1851; Kussmaul and Tenner,¹⁵in 1857; Leiden,¹⁷in 1866; Riegel and Jolly,²¹in 1871; Elder,⁸in 1897; Lewin,¹⁸in 1920, and Lee,¹⁵in 1925.
