    In spite of our previous scientific understanding, the human brain is plastic and ever changing.

    Have you ever considered picking up a new hobby, like playing the violin, only to immediately push away those thoughts, thinking: “I can’t do that! I’m just too old to learn anything new.”

    You’re not alone. The idea that you can’t teach an old dog new tricks was popular among neurologists until the 1970s.

    The thinking was that, once we reach adulthood, the synapses – that is to say, the links between two neurons in the brain – would decay without being replaced. In other words, once the brain was fully developed, it became totally immalleable.

    This idea centered largely around a popular eighteenth-century conception of the brain as a mechanical machine. People thought that the brain worked like a clock comprised of several interoperating components, interlocking like cogwheels. Once the machine had been assembled, it’s function didn’t change, although it might get rusty.

    However, in recent years our scientific understanding has changed dramatically. Today, we know that the brain changes with every action we carry out.

    Consider, for example, the experiment conducted by Michael Merzenich in 1968, in which he amputated a monkey’s finger and observed the brain region that had previously reacted to stimuli from that finger.

    At first, the brain was confused: when Merzenich touched the lower joint of another of the monkey’s fingers, the brain region responsible for the amputated finger also became active.

    However, after a while the brain did something highly unexpected: it rewired itself so that the stimulus caused activity in only the correct areas of the brain.

    Later experiments involving humans showed that the plasticity of the brain – neuroplasticity – is not just limited to the sensory system, but actually applies to all neural activities: throughout our lives, synapses are linking, then strengthening through repetition, or fading from disuse.

    Indeed, you can teach an old dog new tricks.

    What is The Shallows about?

    The Shallows delves into the seldom-asked question of how technology, and the internet in particular, affects our brains. The Shallows looks at the history of technology and recent studies in psychology and neuroscience to show us how the internet fundamentally rewires our neural circuitry, and why it hasn’t delivered the benefits promised by its champions.

    The Shallows Review

    The Shallows (2010) explores how the internet is reshaping our brains and our lives, and why understanding this phenomenon is crucial. Here are three reasons why this book is worth reading:

    • Through compelling research and thought-provoking examples, Carr presents a convincing argument about the impact of the internet on our cognitive abilities.
    • Challenging the notion of multitasking and the value of deep thinking, the book provokes reflection on how we engage with information and the potential consequences.
    • With its engaging exploration of history and neuroscience, the book offers a balanced perspective on the advantages and disadvantages of the digital age and encourages critical thinking.
