Integrated Listening Systems (iLS)
I was intrigued by the Integrated Listening System which uses normal sound waves plus “bone conduction” to supposedly stimulate the cerebellum (at the base of your skull) which in turn talks nice to the pre-frontal cortex (those of you who have read my book know her as Ms. Prefrontal Cortex, the keeper of executive function and responsibility and planning, that sort of thing).
