The story of a neural impulse and what it reveals about how our brains work We see the last cookie in the box and think, can I take that? We reach a hand out. In the 2.1 seconds that this impulse travels through our brain, billions of neurons communicate with one another, sending blips of voltage through our sensory and motor regions. Neuroscientists call these blips "spikes." Spikes enable us to do everything: talk, eat, run, see, plan, and decide. In The Spike, Mark Humphries takes readers on the epic journey of a spike through a single, brief reaction. In vivid language, Humphries tells the story of what happens in our brain, what we know about spikes, and what we still have left to understand about them. Drawing on decades of research in neuroscience, Humphries explores how spikes are born, how they are transmitted, and how they lead us to action. He dives into previously unanswered mysteries: Why are most neurons silent? What causes neurons to fire spikes spontaneously, without input from other neurons or the outside world? Why do most spikes fail to reach any destination? Humphries presents a new vision of the brain, one where fundamental computations are carried out by spontaneous spikes that predict what will happen in the world, helping us to perceive, decide, and react quickly enough for our survival. Traversing neuroscience's expansive terrain, The Spike follows a single electrical response to illuminate how our extraordinary brains work.

This book is quite possibly the most comprehensive book on Australian politics ever written. That''s right, it covers BOTH houses of parliament.We''ll take you inside the halls of power. And if we can''t actually get inside because of security, we''ll do some very fun speculating on what might be in there.One thing we know for sure is that this book is unputdownable. Something went wrong with the printing and it''s all sticky.

Examining sources and case studies, this book explores early Christianity, how it was studied, how it is studied now, and how Judaeo-Christian values came to form the ideological bedrock of western culture. It also includes a guide that lists major collections of literary and non-literary sources, major journals and series, and major text books.
