Discover the powerful and practical guide to strengthening your mind for the modern world and thriving in the age of AI, from acclaimed neuroscientist and Sunday Times bestselling author Dr Hannah Critchlow.

How do we nurture our brains – and our children’s brains – so we have the resilience to thrive during the coming wave of technological and societal change? How can we keep up in the face of AI?

The 21st Century Brain provides the answers.

In her empowering and practical new book, bestselling neuroscientist Dr Hannah Critchlow takes you on a journey through the fascinating landscape of the latest neuroscience research, detailing how we can develop the essential human skills that technology cannot replace – and that matter most for personal fulfilment, wellbeing and long-term success.

Grounded in the latest science, you’ll discover how to strengthen and future-proof essential skills, including:
· Emotional intelligence and collaboration
· Imagination, creativity, and flexible thinking
· Long-term thinking and decision-making
· Adaptability and mental resilience
· Intuition, loyalty, and connection

Writing in her informative and accessible voice, Dr Critchlow shows why our greatest strengths lie not in competing with machines, but in becoming more fully human.

Blending fascinating research with practical advice and simple brain exercises, The 21st Century Brain is the must-read guide to navigating rapid technological change with confidence.
