The Effects of Musical Intervals from Consonant to Dissonant on the Neural Activity of Earthworms

<p>Music is generated through vibrations of a medium creating what is perceived as tone. Two frequencies played simultaneously create intervals, and those ratios of frequencies determine what is consonant and dissonant. Studies have shown a greater neural response in human participants to consonant intervals (Bidelman and Heinz 2011, Bidelman and Krishnan 2009). In this study, the ventral nerve cord of <em>Lumbricus terrestris</em> was exposed to six dichotic intervals in the form of vibrations through a bass actuator. Nerve activity was recorded for amplitude (mV), duration (ms), and maximum depolarization (mV) of the action potential. There was no significant difference in amplitude, duration, or maximum depolarization across all six interval treatments.</p>
