The widely-considered hypothesis of attribute-binding by brain wave coherence may be extended to consideration of the small numbers of items that fill each moment’s working memory (WM) capacity: Perhaps each of up to 3 or 4 WM items is marked by a different EEG frequency. According to my hypothesis, prevention of difference-rhythm “aliases” suggests all such frequencies occur within an “octave” band, in which the upper bound is twice the lower (see my SfN abstracts, 1994-2003, and articles in Brain Res. Bull., 1999, 2003; Prog. Neuro-Psychopharmacol. & Biol. Psychiat., 2000; and Chapter 10 of Time and Mind II - H. Helfrich, ed., Hogrefe & Huber, 2003). Elsewhere, I present the programs for EEG and WM-behavior data acquisition, and an EEG amplifier schematic using a quad op-amp chip (Note: Electrical safety requires care). Here, I give source code written in G, an iconic language (LabVIEW; National Instruments, Austin TX), intended for off-line analysis of waveforms recorded to a file. The program uses buil...
