Mant years ago, the New York Neuropsychology Group had either Cracco or
Macabee (Downstate Med Ctr, Broooklyn) speak on their then vry new
magnetic stimulation work. Since then there have been MAN, MANY
studies employing this technique; it seems to me with some acceleration
in the rate of use over the past 3-4 years.
How local? Well, in the early applications, movement of (e.g.) one
thumb was the goal. Subsequent targets have been more interesting
(looking more at cognitve/perceptual questions), but this gives you an
idea of the focus which is easily obtained. (Haven't followed it, so
don't knoow how fine the focus can get.)
NOT a good way for "feeding information" into brains; better suited to
interfering with activity in a given area, with inferences about
localization (perhaps even timing) based on interruption of information
There is also direct electrical cortical stimulation, from Penfield
(over half a century ago) to (e.g.) Ojemann, currently. Much the same
comments apply. This is, however quite invasive.
As an undergrad philosophy major, I of course studied metaphysics. My
impression is that this is not what gets labeled metaphysics in popular
forums (i.e. neither science nor philosophy). Probably would not be
