NCT06229093

Brief Summary

This is a Stage I randomized, sham-controlled trial on the effects of multimodal musical stimulation on working memory in aging. Neurologically healthy older and younger adults will be tested on working memory and electroencephalography in the first randomized controlled trial of music as a form of brain stimulation, with multimodal musical stimulation and control stimulation conditions. Results will test the causal role of oscillatory mechanisms of the brain on cognition, and will lay the groundwork to the first musical, neurophysiologically targeted, brain-stimulation device for reversing cognitive decline in aging.

Older Adults (OA)

SHAM COMPARATOR

The assignment of older adults to OA and OAg will be randomized. The within-subjects factor of stimulation modality includes 2 levels, to be administered in counterbalanced order: Visual (V, i.e., lights-only) and Audiovisual (AV, i.e., music-plus-lights). Each subject will be aware that they are receiving V and AV stimulation, and thus infer that we are comparing these two forms of stimulation and therefore assessing the effects of music. However, and important to the design of this study, all subjects will be blinded with respect to their group assignment; i.e., they will not know, until post-study debriefing, about the other arms of the study, and that the gamma-band stimulation is an active ingredient of the intervention.

Interventions

GammaDEVICE

For the OAg group, the visual component of multimodal stimulation will have the same properties as for the other group, except it will also be additionally amplitude-modulated in the gamma-band (30-60 Hz) range, resulting in a detectable flicker over-and-above the beat-level modulation.

Older Adults Gamma (OAg)
SynchronyDEVICE

For the OA group, the lights will be tuned to delta-band frequencies (1-4 Hz) in the music, which corresponds to the beat-level frequency in most music. Thus, the lights automatically adapt to the rhythm of the music, pulsing on the beat and changing color on strong beats.

Older Adults (OA)

Eligibility Criteria
