The brain is an enormously dynamic organ. Even when we sleep connections are made, signals sent and messages delivered. One of the key ways that the brain operates is via chemical stimuli which permits different parts of the brain to communicate between themselves and with the rest of the body. Determining what these chemicals, proteins and molecules are is an important way to not only discover how the brain works, but provide novel targets that may be useful in the treatment of disease, for instance in dealing with memory loss in dementia. This new book brings together international research in a broad range of topics including molecular and cellular neurochemistry, neuropharmacology and genetic aspects of CNS function, neuroimmunology, metabolism as well as the neurochemistry of neurological and psychiatric disorders of the CNS.
