In his deeply engaging, topical and thought-provoking book, Dr. Richard Restak, a neurologist and neuropsychiatrist, explores the "plasticity" of the human brain and how it is physically changing in response to the digital era.

Restak argues that the brain is not a static organ but a dynamic one that adapts to its environment. Because we now live in a world of constant technological stimulation, our neural pathways are being "rewired" to handle new types of information processing.

The book explores a number of key areas and themes, among them:

- Neuroplasticity: how the adult brain remains malleable. Activities like video gaming or heavy internet use don't just change our thoughts; they change our physical neural maps;

- The Multitasking Paradox: Restak examines how the modern demand for multitasking affects the prefrontal cortex. He suggests that while we feel more productive, we may actually be decreasing our ability to focus deeply and to undertake deep work;

- Hyper-Attention vs. Deep Attention: The author discusses the shift from "deep attention" (focusing on one thing for a long time, like a book) to "hyper-attention" (switching rapidly between different streams of data);

- Technology and Mental Health: Restak touches on how this "high-tech" environment contributes to the rise of conditions like ADHD and stress-related disorders due to sensory overload.

As a medical professional, Restak balances the excitement of new technology with a cautious look at the biological costs of living in a 24/7 digital society. He provides a roadmap for how to harness these changes without losing our capacity for reflection and emotional depth.

This book could not be more relevant today, coming at a time when major questions are being asked by society about the short- and long-term neurological affects of social media on children, teens and young adults with calls for greater recognition and regulation of digital tech's societal impacts.
