Researchers from the Institute of Neuroinformatics of the University of Zurich (INUZ) and ETH Zurich have published a study showing just how smartphones are altering our brains through the advent of text messaging.

Literally, human brains are now evolving to fit the incessant use of smartphones through alterations in the somatosensory cortex (SSC) and our ability to move our fingers.

The SSC is plastic in the sense that it can change throughout a human lifetime. With the advent of texting, the SSC is growing larger in people who use their smartphones more often; just as a violin player’s SSC is larger because of the time taken to practice.

Using electroencephalography (EEG) monitoring, a group of 37 participants allowed their brains to be scanned while using a smartphone and an “old-style” cellphone.

The researchers discovered that “the cortical activity in smartphone users was quite different from those using traditional cellphones. The more the smartphone users had used their phones in the previous 10 days, the greater the signal observed in the somatosensory cortex. And this link was strongest in the brain areas that controlled the thumbs.”

Critics state that “smartphones make us masters of information mediums the world has begun to value most. But we evolved to be hunter-gatherers, not digital data micromanagers.”

Arko Ghosh, professor with the INUZ and lead author of the study explained that because of the overuse of smartphones, scientists can understand how “normal life shapes the brains of ordinary people. The digital technology we use on a daily basis shapes the sensory processing in our brains — and on a scale that surprised us.”

Journalist Jim Algar joked that “the next generation will evolve thumbs perfectly suited to texting on their smartphones.”

In the study entitled, “Searching for the Google Effect on People’s Memory”, researchers at Columbia University (CU) found that “humans are actually starting to use the gigantic knowledge repository that is the Internet as a personal memory bank, rather than a simple information resource.”

Another study showed that 50% of the 55 year old volunteers were “net-savvy”.

Technology has yielded interesting promises such as a pill that causes your sweat to smell like perfume and the possibility of a 3D printed kidney .
