Every song ever written started with a first experimental musical note of the composer. In the same way, every essay, every letter, every book, every blog post, started with that first mental note of the author. Most of the time, our ideas and experiences float away and we forget them. Sometimes, we jot a thought down, remember it, and it leads to new experiences. Sometimes an idea, an experience, a name and phone number, or a note-to-self remembered rather than forgotten, makes the difference in the direction of our lives.

Taking notes can translate a fleeting conception in our brain into action, and that action usually involves sharing our experience or idea with someone else. As we carry more and more powerful technology around with us every moment of the day, might it be possible that we can start to translate more of our otherwise forgotten notes-to-self and fleeting experiences into shared experiences? Into the start of conversations that make our lives richer?

In 1995, Bill Gates concluded his book The Road Ahead with a prescient but disquieting idea: Carrying around mobile technology connected to networks would lead to the fully “documented life”:

“Your wallet PC will be able to keep audio, time, location, and eventually even video records of everything that happens to you. It will be able to record every word you say and every word said to you, as well as your body temperature, your blood pressure, the barometric pressure, and a variety of other data about you and your surroundings.… It will be able to track your interactions with the network—all of the commands you issue, the messages you send, the people you call or who call you.”

Phineas Gage

Growing up, I learned about Phineas Gage, the railroad construction foreman who survived an incredible accident in 1848 that shot a large iron rod through his brain, destroying the frontal lobes. Although Gage survived for another decade, his personality changed profoundly. The brain science books I read in the late 1980’s still used the over century-old example to introduce the idea that every function had a special location in the brain, and everything was hard-wired for life once you finished childhood. It turns out the hard-wired model of the brain was dead wrong, and academic opinion and dogma had led research down the wrong path for over 100 years.

Dr. Michael Merzenich, founder of Posit Science and one of the world’s leading brain scientists helped disprove the old “what you have is what you get” brain theories. In the 1980’s, Merzenich’s team developed the cochlear implant, a device that stimulates nerves in the inner ear with electrical signals that correspond to sound. With the “bionic ear”, people with profound deafness have learned to process the electrical signals and hear again. Merzenich went on to show that the brain can adapt and change based on all sorts of sensory input. How neurons wire together not only changes based on our experience with the world, but also based on our own thoughts. Posit Science applies this new knowledge of brain plasticity to brain training and brain fitness products that improve memory and processing speed to treat age-related cognitive decline.
