Can electromagnetic fields be used to stimulate areas of the brain? Recently I've come across an article from a questionable source called 10 Things An Electromagnetic Field Can Do To Your Brain. 

There are a lot of hints in this article that the writer doesn't have a strong understanding of what they are talking about, i.e. referring to electromagnetic waves as being 'high' and 'medium'. They could be high energy, high frequency, but not 'high'. 

Regardless of the accuracy or technical mistakes of the writer, I would like to know if there is a lot of truth to this article. The article suggests that areas of the brain were targeted and stimulated with electromagnetic waves.

I know about TMS (Transcranial Magnetic Stimulation) devices which stimulate the brain via magnetic fields and tDCS which stimulate the brain via electric current, but I have never heard of any tEMS (transcranial Electro-Magnetic Stimulation) devices. Do they exist? 

I've done some searches, but have only come up with results to the more common TMS device.
Maybe this is not what you expected, but since you mentioned electro-magnetic stimulation, I'd like to mention optogentics, where light (electro-magnetic waves) are used to 


  control cells in living tissue, typically neurons, that have been genetically modified to express light-sensitive ion channels.
