Crop milk production in pigeons is stimulated by the hormone prolactin. (This is the same hormone that stimulates milk production in mammals.) Interestingly, prolactin produces an overall calming effect. Which fact leads neatly to a discussion of ‘calming’ and the effects of pigeon cooing on the human mind.
Predicated on the hypothesis that the human mind is pleasantly relaxed by the sound of pigeon cooing, we imagine the following experiment.
A range of volunteers, outfitted with electro-caps, is subjected to alternate recordings of circus music and pigeons cooing in the park. Brain activity is recorded. The simplicity of the data imaging is humble, especially when juxtaposed against the spectacular imaging techniques driving today’s science. However simple, we find it illustrates the point.
To deepen our understandings, we ask you take the time to complete the brief survey below.
