Can Cell Phones Increase Brain Power?

But before you decide to ditch the landline and go cellular in the hopes of
improving your brainpower, Koivisto warns that you won't notice a difference.
"The effects are so small ... that they have no practical implications.
These effects can only be observed in laboratory conditions," he says.
Fitzsimmons agrees. "I don't think this is anything that is going to be
used constructively," he says. "It is just one of those things that is
interesting ... and shows that it is not always just a simple matter of saying
something is bad or it's good, because at different levels you have quite
different effects. And this is definitely low level."
Koivisto's work is only a small piece of the cell phone and health puzzle --
a puzzle for which no one seems to have the picture on the box as a guide.
Although many studies show that there are no adverse health effects
associated with cell phone use, the FDA isn't ready to call them
"absolutely safe" just yet. The agency's concern is that cell phones
emit low levels of radiation while in use, and even smaller amounts when not in
use. It is known that high levels of this radiation, which is the kind used in
your microwave oven, can cause damage to tissue because it heats it up, but
it's not known what low levels of the radiation does.
Last week, the FDA announced that it will collaborate with the Cellular
Telecommunications Industry Association over the next three to five years to
investigate mobile phone safety by recommending and funding research. The
research would be conducted by third parties.
