This introduces a random or stochastic property into brain processing which we show in this book is fundamental to understanding many aspects of brain function, including probabilistic decision making, perception, memory recall, short-term memory, attention, and even creativity. We show that in many of these processes, the noise caused by the random neuronal firing times is useful.

However, this stochastic dynamics can be unstable or overstable, and we show that the stability of attractor networks in the brain in the face of noise may help to understand some important dysfunctions that occur in schizophrenia, normal aging, and obsessive-compulsive disorder. The book provides a unifying computational approach to brain function which links synaptic and biophysical properties of neurons through the firing of single neurons to the properties of the noise in large connected networks of noisy neurons to the levels of functional neuroimaging and behaviour.

Integrate-and-fire neuronal attractor networks with noise, complementary mean-field analyses using approaches from theoretical physics, and how they can be used to understand neuronal, functional neuroimaging, and behavioural mechanisms data on decision making, perception, memory recall, short-term memory, attention and brain dysfunctions that occur in schizophrenia, normal aging, and obsessive-compulsive disorder, are described.

The Noisy Brain will be valuable for those in the fields of neuroscience, psychology, cognitive neuroscience, and biology from advanced undergraduate level upwards. It will also be of interest to those interested in neuroeconomics, animal behaviour, zoology, psychiatry, medicine, physics, and philosophy. The book has been written with modular chapters and sections, making it possible to select particular Chapters for course work. Advanced m
