needles in the original Morrison experiment" to mean that he
held the needles between his thumb and index finger, as Dr.
Morrison did. As a result, this test demonstrates that the
heartbeat in Falkowski's thumb and index finger caused some
light modulation, albeit at levels slightly below the minimum
levels required by a conventional oximeter (i.e., 0.05 to
0.07% ). In fact, Dr. Morrison admitted that some needle104
spacing variations may have occurred, though he doubted they
were detectable. Specifically, when asked whether this
modulation of the needle distance could have created a pulse

artifact, he responded:
It may be possible, but it would not be expected to
produce a normal kind of saturation. It would be
detected as perhaps a pulse, but generally not
reported by the oximeter as a valid saturation
reading unless you could be extremely consistent
about the motion artifact thus produced.
Q. Isn't the pulse in your thumb a consistent pulse?
A. Yeah, but you have to have a consistent pulse, you
have to have consistent pressure, consistent spacing
between the ends of the needles. There are too many
factors that must remain consistent for you to
