The third likely place for the detection mechanism is the brain. Burr
and Mauro (6) presented evidence that indicates that there is an
electrostatic field about neurons.  Morrow and Sepiel (7) presented
evidence that indicates the existence of a magnetic field about
neurons.  Becker (personal communication) has done some work
indicating that there is longitudinal flow of charged carriers in
neurons.  Thus, it is reasonable to suspect that possibly the
electromagnetic field could interact with neuron fields.  As yet,
evidence of this possibility is inconclusive.  The strongest point
against it is that we have not found visual effects although we have
searched for them.  On the other hand, we have obtained other
nonauditory effects and have found that the sensitive area for
detecting rf sounds is a region over the temporal lobe of the brain.
One can shield, with a 2-in.2 piece of fly screen, a portion of the
stippled area shown in Fig. 6 and completely cut off the rf sound.

Another possibility should also be considered.  There is no good
reason to assume that there is only one detector site.  On the
contrary, the work of Jones et al. (8), in which they placed
electrodes in the ear and electrically stimulated the subject, is
sufficiently relevant to suggest the possibility of more than one
detector site. Also, several sensations have been elicited with
properly modulated electromagnetic energy.  It is doubtful that all
of these can be attributed to one detector.

As mentioned earlier, the purpose of this paper is to focus the
attention of physiologists on an unusual area and stimulate
additional work on which interpretations can be based.
Interpretations have been deliberately omitted from this paper since
additional data are needed before a clear picture can emerge. It is
hoped that the additional exploration will also result in an increase
in our knowledge of nervous system functions.
