In 2002 Paul Pearsall from
the University of Hawaii and his colleagues from the University of Arizona
looked at the unique memory experiences being reported by heart transplant
patients over a ten-year period. After interviewing 150 patients he reports
nine cases were recipients of a new heart took on characteristics and
desires/fears of their heart donors. These included changes in preferences for
food, music, art, sexual, recreational, and career, as well as specific
memories only privy to the donors.
Weird
stuff. Explaining such outcomes is difficult if you want to stay in
the realm of science.
In Chinese Traditional
Medicine it is believed your heart stores your memory. Reigniting painful
memories of secondary school pedagogy when we were told to learn “by
heart.” So where is memory?
We are learning about the
language of how the environment communicates. And such knowledge is adding to our
knowledge of how we see our internal body communicating.
An example of what this language
might look like can be found in the plant kingdom. In short distance
communication, Nigel Raine from the University of London and his colleagues
observed how ants provide a useful service for the acacia plants by guarding
the plant they live on. Tomatoes and tobacco plants have similar symbiotic
arrangements. Wouter Van Hoven from Pretoria University reports that acacias
also produce leaf tannin in quantities lethal to the antelope and thereby
killing the antelopes while at the same time emitting ethylene into the air
which can travel up to 50 yards warning other acacias to step up their own
production of leaf tannin within just five to ten minutes. Willows have been
found to have a similar strategy when they are being eaten by caterpillars.
These are complex communication strategies.
Jim Westwood, a plant
scientist at Virginia Tech showed how a parasitic weed known as
dodder/strangleweed, uses its RNA—its genetic material--to communicate with
their host plants that they are nurturing from, in order for the host plant to
lower its defenses.
Back to our bodies, the
Danish biologist Bente Klarlund Pedersen is looking at a handful of
myokines—a protein he identified and named—and their role in helping skeletal
muscle retain memory. He acknowledges there are several hundred other secreted
proteins giving internal body communication a complex language.
There is also evidence that
midkine--another protein--is exchanged between the lungs and kidneys so that
they “know” each other’s status. However, little is known about how the
information is transferred from one organ to the other. Paul Pearsall’s
findings should make us think about how our bodies stay in balance and how
memory is not solely the prerogative of the brain. When this balance is
disrupted, what messages is the dying organ sending out? What is our body
communicating at the end of life?
