Pulse of the Early Brain

Pulse of the Early Brain is a compilation album by the English-French avant-pop band Stereolab, released on 2 September 2022 under Duophonic Records and Warp Records. It is the fifth installment of the band's Switched On series which collects the band's rarities, such as the extended plays (EPs) Simple Headphone Mind (1997) and Low Fi (1992); bonus and exclusive tracks from Chemical Chords (2008); and individual tracks from other albums, split singles and flexi discs. Unlike previous Switched On releases, which compiled each of the band's eras in chronological order, Pulse of the Early Brain covers rarities from all over their career.

The compilation was announced with the release of the single "Robot Riot" in June 2022 and the singles "Simple Headphone Mind" and "Trippin With the Birds" in August. Pulse of the Early Brain received acclaim from music critics, who praised the inclusion of Simple Headphone Mind and Low Fi. It ranked at number 3 in the UK Independent Albums Chart and at number 66 in the UK Albums Chart.
