Alpha and low gamma embedded with white noise binaural beats modulating working memory among Malaysian young adults: an exploratory fMRI study

Introduction: Exposure to alpha and gamma binaural beats (BB) have provided inconsistent findings in its modulating role of working memory (WM). White noise (WN) has acted as a control condition. Objective: The study aims to explore the effect of load on the effectiveness of WN embedded BB on WM...

White noise (WN) has acted as a control condition. Objective: The study aims to explore the effect of load on the effectiveness of WN embedded BB on WM performance using functional magnetic resonance imaging.

Results: Six young adults (3 males and 3 females) within the Kota Bharu vicinity were recruited with mean age of 23.5 ± 0.84. The twoway repeated measures ANOVA (p<0.05) on response accuracy shows there is no significant main effect for conditions and load.

There is no interaction effect of conditions and load on RT.

Two-way repeated measures ANOVA (p<0.05,uncorrected) of the WM task further supports the aforementioned modulation in post-BB activations with the activation of thalamic regions in GWN and frontoparietal regions in AWN.
