In his previous books, Oliver Sacks had addressed questions of the brain and mind through the lens of case histories of individuals with neurological disorders.  The River of Consciousness will be a broader and more direct look at how the brain and mind work, as always, incorporating Sack’s rich historical and personal context. Advances in neuroscience have revolutionised our ability to visualise the brain in action. For the first time we are able to close the gap between the philosophical questions which have consumed the world’s thinkers since the eighteenth century and the true physiological basis of perception and consciousness. In The River of Consciousness, Sacks will examine questions of memory, time, and consciousness. How do we think, how do we remember? Do different individuals have different speeds or ways of thinking? Is memory reliable? And most importantly, what is creativity?
