Neuroscience, Advertising & Emily Dickinson?

I really enjoyed Dickinson's poem and its analysis mainly because I am fascinated by the brain and the way it works. The brain is a superpower computer whose potential is unfathomable. At any given time our conscious brain is able to process 40-50 bits of information per second. Meanwhile, our subconscious brain is able to process up to 11 million bits per second. Therefore we make connections and pick up on things we never know. 

Back in the mid-20th centuries when cinema and TV's were still fairly new, clever advertisers exploited the power of the subconscious mind to increase sales. In the cinema, they would insert a photo of popcorn for a fraction of a second, long enough for the subconscious mind to pick up on but quick enough to not let the conscious mind process this information. As our subconscious mind is responsible for 90-95% of our actions, the popcorn was at the forefront of the viewers mind. They would then get up and buy popcorn at a more frequent rate then when these micro second images were not displayed. This practice was later outlawed as it was found to exploit people's minds. 

In her poem, "The Brain-is wider than the Sky," Emily Dickinson compares the brain to the sky, the sea and God saying that they're wider, bigger and equal, respectively. She understands the power of the brain and its potential.
