The sound appears to pulsate only when heard through both earphones. Time duration of 10 seconds Binaural Beats Base tone 200 Hz, beat frequency from 7 Hz to 12.9 Hz. Time duration of 9 minutes. "Binaural beats were first discovered by physicist Heinrich Wilhelm Dove in 1839.
Currently, there are arguments that alpha patterns are a normal part of REM sleep, and for the notion that it indicates a semi-arousal period. It has been suggested that this alpha activity is inversely related to REM sleep pressure. [citation needed] It has long been believed that alpha waves indicate a wakeful period during sleep.

The Franssen effect is an auditory illusion where the listener incorrectly localizes a sound. It was found in 1960 by Nico Valentinus Franssen (1926–1979), a Dutch physicist and inventor.
AZD1305 blockade of the INalate modulates IKr-blockade induced APD instability, repolarization vulnerability, and variability in beat-to-beat APD. [ 4 ] [ 5 ] In vivo , as well as in vitro studies discovered that inhibition of INa and IKr by AZD1305 is much greater in atrial versus ventricular myocytes.
