“Without consciousness, life would indeed be pretty much the same as death. The conscious condition makes life worth living: yet what is it, this insubstantial, intangible inner … what exactly?”

Consciousness, once the province of philosophers and theologians, has become in the past few decades one of the great scientific challenges, a fascinating topic of research in psychology and neuroscience.

Susan Greenfield, a Senior Research Fellow at Oxford University, heads a multi-disciplinary research group exploring novel brain mechanisms linked to neurodegenerative diseases. In her book A Day in the Life of the Brain draws on her own research to illuminate the mystery of consciousness in the course of a single day in the life of the brain.

Susan Greenfield takes everyday activities – waking up, walking the dog, eating breakfast, at the office, problems at home, sleeping and dreaming – to explore how the human brain is working. Her theory is that coalitions of millions of neurons are responsible for consciousness. These ‘neuronal assemblies’ play a central role in organising all the networks in the brain and somehow these neuronal assemblies provide a collective continuous experience of consciousness.

The book shows how the brain works, its complexity and the functionally of certain areas. It   has some good insights and it is written in a simple style, devoid of difficult jargon. It sheds some light on consciousness.
