The starting point of this interesting compact book is the recognition that two camps of professionals specialize in understanding cognitive functions: neuroscientists who primarily evaluate healthy individuals, and clinicians who work with brain-injured patients. Each group has a select acquaintance with cognitive functions, conditioned by the populations that it addresses, while having more limited understanding of the cognitive processes associated with the other group. Thus, this book attempts to bridge health and disease by showing how normal cognitive functions may be corrupted by brain illness, and thereby foster an improved understanding of cognitive processes in general.
