40 Hz Blue Light and Memory Research
The study titled “40-Hz Blue Light Changes Hippocampal Activation and Functional Connectivity Underlying Recognition Memory” explored how rhythmic 40 Hz blue light relates to brain activity during memory tasks. Using fMRI, researchers observed that 40 Hz light exposure was associated with increased activation in memory-related regions, including the hippocampus, and stronger connectivity with sensory-processing areas.
These findings suggest that rhythmic 40 Hz light may help the brain maintain patterns of gamma activity linked with focus, learning, and memory. The research contributes to ongoing exploration of how light frequencies interact with cognitive and neural function.
