1934 E. D. Adrian & B. H. C. Matthews in Brain 57 356 Since the effect is so characteristic we shall refer to it in future as the Berger rhythm.

1936 Arch. Neurol. & Psychiatry (Chicago) 36 1215 Most prominent is a rhythm of approximately 10 a second..variously known as the ‘Berger rhythm’, the ‘alpha waves’ or the ‘10 cycle rhythm’.

1938 Jrnl. Neurol. & Psychiatry 1 366 Berger's first papers described two electrical rhythms. The first, which he called ‘alpha waves’ and which was referred to five years later by Adrian and his collaborators as the ‘Berger rhythm’, consists of an almost sinusoidal discharge with a frequency of about 10 per second and with a potential varying irregularly from zero to about 100 microvolts.

1941 P. Bard Macleod's Physiol. in Mod. Med. xix. 238 The most prominent rhythm is one which ranges from 8 to 13 and averages 10 waves a second. This is sometimes called the ‘Berger rhythm’, but has more generally come to be known as the alpha rhythm.
