A marvellous account of the brain's creative powers in perception and imagination, beautifully written, bringing novel insights to bear on the richness of mental life: Zeman is the poet of this science, bringing into seamless connection neurology, neuropsychology, artistic creativity and lived experience at the opposite ends of a scale - from those capable of forming exceptionally vivid mental pictures to those unable to do so at all – and what everything in between means for the way brains construct our worlds. Fascinating, absorbing and educative

Rarely does one come across a scientific book that one simply does not want to put down. This is an immensely readable account of how the human imagination works, and of its ramifications in all areas of our lives. Adam Zeman is an extremely companionable writer, leading us courteously through the byways of neuroscience and psychology as he expounds his fascinating subject. This book is a triumph. It is a work of great importance that touches upon many of the issues that beset our world today

What is it like to live without mental images, to imagine without a mind's eye? In The Shape of Things Unseen, pioneering neurologist Adam Zeman leads us through the mysterious world of aphantasia. It's an intoxicating journey. Zeman is a gifted writer and storyteller and manages to do justice to the poetry of the mind as well as the science. I have a feeling this book is destined to become a classic of narrative neuroscience

A profoundly useful roadmap to one of the most mysterious aspects of the universe, The Shape of Things Unseen is a clear-eyed, engaging overview of how the imagination works. It reveals its central role in perception and memory, and the extent to which it has differentiated us from the rest of the animal kingdom. Recommended reading for any mind that wants to understand itself
