	"The researchers performed several variations of this experiment to test the effects of different intensity levels, current directions and electrode placements. This third experiment was important because it confirmed that the electrodes had to be positioned specifically over the brain . . ." "The researchers stress that . . . members of the public should never attempt to replicate the experiment at home." __________________ ci139

	The only way I can see that this makes any sense is that if the electrical stimulation somehow aids in the eye focusing (Accommodation) https://en.wikipedia.org/wiki/Accommodation_(eye)

	I would actually compare this with data processing in a digital camera. Granted, an image must be laid down on a sensor (the retina), but the interpretation of that image is left to a small computer in the digital camera and to the visual cortex in the brain. Although the effect surprises me somewhat, I can compare the effect of electrical stimulation to the effect of adding a Photoshop filter.

	You make a very good point. There is a lot of image processing that goes on in the visual system after the image is laid down on the retina. The brain and nervous system is adaptive, and I can conceive of the visual cortex of an individual with poor eyesight "learning" a "sharpening filter". Somehow the electrical stimulation aids in this process. GA.
