![]() The purpose of the current study is to investigate the effectiveness of isochronic tones in stress reduction and auditory brainwave entrainment. 020) in absolute alpha band power, indicating a greater presence of absolute alpha in the absence of isochronic tones and contradicting the hypothesized effectiveness of isochronic tones. A two sample t-test showed a significant difference ( p =. 509) in subjective stress between isochronic conditions. ![]() A Mann-Whitney U (Mann & Whitney, 1947) showed no significant difference ( p =. Participants completed a pre-ESRQ and EEG analysis, listened to their assigned song for five minutes, then completed a post-ESRQ and EEG analysis to measure for changes as a result of the presence or absence of isochronic tones in their assigned condition. Sixty undergraduates were randomly assigned to listen to a song containing or absent of isochronic tones in a double-blind procedure. The current study examined the lasting effect of 8 Hz alpha isochronic tones on subjective stress, via Larsson’s (2011) ESRQ, and absolute alpha band power, via an EEG. Though Isochronic tones are commercially marketed as effective in brainwave entrainment, there is limited empirical investigation to date to substantiate this claim this is particularly true of alpha cortical entrainment via isochronic tones. Brainwave entrainment, also referred to as neural synchronization, is a phenomenon by which external stimuli influence neural oscillations related to specific cognitive states (Siever, 2012). Dr.Isochronic tones are a hypothesized auditory brainwave entrainment technique in which a single tone is played at regular beat intervals.Eddie Chang: The Science of Learning & Speaking Language (Huberman Lab episode) ![]() Tools to Manage Dopamine and Improve Motivation & Drive (Huberman Lab episode).Controlling Your Dopamine For Motivation, Focus & Satisfaction (Huberman Lab episode).How to Increase Motivation & Drive (Huberman Lab episode).40-Hz Binaural beats enhance training to mitigate the attentional blink ( Scientific Reports).Music versus midazolam during preoperative nerve block placements: a prospective randomized controlled study ( Regional Anesthesia & Pain Medicine).Effects of music on the cardiovascular system ( Trends in Cardiovascular Medicine).Whether you sing, play an instrument or enjoy listening to music, this episode provides numerous science-informed tools for using music to enhance productivity, mood, emotional states, and overall enjoyment of life. Finally, I discuss how music helps to enhance neuroplasticity (rewiring of brain connections), thereby improving learning and memory. ![]() I explain how listening to certain types of music can improve various health metrics (e.g., heart rate). I also discuss how specific musical pieces can rapidly reduce anxiety, as well as certain prescription medications. I explain the data showing how music can increase motivation for cognitive or physical work, what specific music has been shown to enhance cognitive performance, and whether silence or music is more effective in enhancing focus while studying. In this episode, I describe how your brain and body are fundamentally wired to perceive and respond to music and how those responses can be leveraged to improve your mood, allow for processing sad emotions and enhance learning and performance.
