By Edmund T. Rolls

The task of neurons within the mind is noisy in that their firing occasions are random once they are firing at a given expense. This introduces a random or stochastic estate into mind processing which we convey during this ebook is prime to figuring out many points of mind functionality, together with probabilistic selection making, conception, reminiscence remember, temporary reminiscence, awareness, or even creativity. We express that during lots of those techniques, the noise attributable to the random neuronal firing instances comes in handy. despite the fact that, this stochastic dynamics will be risky or overstable, and we express that the steadiness of attractor networks within the mind within the face of noise can help to appreciate a few very important dysfunctions that happen in schizophrenia, common getting older, and obsessive-compulsive disorder.

The publication presents a unifying computational method of mind functionality which hyperlinks synaptic and biophysical homes of neurons during the firing of unmarried neurons to the homes of the noise in huge hooked up networks of noisy neurons to the degrees of sensible neuroimaging and behavior. Integrate-and-fire neuronal attractor networks with noise, complementary mean-field analyses utilizing ways from theoretical physics, and the way they are often used to appreciate neuronal, sensible neuroimaging, and behavioural mechanisms facts on selection making, belief, reminiscence keep in mind, momentary reminiscence, recognition and mind dysfunctions that take place in schizophrenia, basic getting older, and obsessive-compulsive disease, are described.

'The Noisy mind' could be priceless for these within the fields of neuroscience, psychology, cognitive neuroscience, and biology from complicated undergraduate point upwards. it is going to even be of curiosity to these attracted to neuroeconomics, animal behaviour, zoology, psychiatry, drugs, physics, and philosophy. The ebook has been written with modular chapters and sections, making it attainable to pick specific Chapters for direction paintings. complicated fabric at the physics of stochastic dynamics within the mind is inside the Appendix.
