In
1980, a nine-year-old boy was reported to have developed incredible mechanical
skills after sustaining a bullet wound to his left-brain. "These skills
included being able to dismantle, reassemble, and improve multi-gear bicycles
as well as invent a punching bag that simulated the bobbing and weaving of a
live opponent (Treffert, 2014)." This is just one example of a handful of people in our
world who were fortunate enough to have their inner savant released after
suffering a major cognitive injury. This amazing anomaly is labeled acquired
savantism and can be defined as "an alternate form of the condition in which a
person develops the ability to paint, play music or do mental calculations
after experiencing some form of brain injury (Treffert, 2014)." In an article published by
Scientific America, this phenomenon is explored at length and examples are
given of many other traumatic brain injuries that resulted in the near
genius-level abilities of its victims. But how does this truly rare and
shocking condition relate to perception? I want to focus on one particular
brain disorder the article mentioned called frontotemporal dementia (FTD) to
answer this question. FTD is a degenerative process of the brain that has
resulted in "elderly patients demonstrating musical or artistic abilities
for the first time, sometimes at prodigious levels, after their diagnosis. FTD
often targets the left anterior temporal area of the brain and the
orbitofrontal cortex. Both regions normally inhibit activity in the visual
system at the back of the brain, which is involved in processing incoming
signals from the eyes. This disease seems to foster a newfound artistic
sensibility by turning off inhibitory signals from the front of the
brain (Treffert, 2014)." Thus, this pivotal change in inhibited cognitive function allows the brain
to perceive and process sight and sound in numerous different ways than ever possible before. Thus, this degenerative process releases creative
sensibilities that cannot be fathomed during normal functioning. Ultimately, I
find this truly rare occurrence fascinating and I hope you all do too!
