10 Hz flicker improves recognition memory in older people.

BACKGROUND: 10 Hz electroencephalographic (EEG) alpha rhythms correlate with memory performance. Alpha and memory decline in older people. We wished to test if alpha-like EEG activity contributes to memory formation. Flicker can elicit alpha-like EEG activity. We tested if alpha-frequency flicker enhances memory in older people. Pariticpants aged 67-92 identified short words that followed 1 s of flicker at 9.0 Hz, 9.5 Hz, 10.0 Hz, 10.2 Hz, 10.5 Hz, 11.0 Hz, 11.5 Hz or 500 Hz. A few minutes later, we tested participants' recognition of the words (without flicker). RESULTS: Flicker frequencies close to 10 Hz (9.5-11.0 Hz) facilitated the identification of the test words in older participants. The same flicker frequencies increased recognition of the words more than other frequencies (9.0 Hz, 11.5 Hz and 500 Hz), irrespective of age. CONCLUSION: The frequency-specificity of flicker's effects in our participants paralleled the power spectrum of EEG alpha in the general population. This indicates that alpha-like EEG activity may subserve memory processes. Flicker may be able to help memory problems in older people.

One can't help but wonder if a 10 hz flicker improves recognition memory WHY can't anyone prove other frequencies/oscillations/pulsations, etc. can actually cause harm? We know the answer, of course -- THEY don't want to acknowledge that which causes serious adverse health effects but rather, acknowledge only "biological effects" which are claimed to be meaningless!!! How much longer do scientists think they can continue to report therapies, etc. without admitting there are limits beyond which adverse health effects definitely occur?
