'This is a very timely, comprehensive textbook that focuses on the next frontier in clinical neurosciences - how the immune system modulates the body responses that will affect the brain and its functioning - including a likely intersection with nutrition and immune responses that take place in the digestive system. The editors assembled a stellar team of leading scientists covering these inter-related disciplines and research areas. It will be a must-read for all interested in the intricacies of these complex relationships, and the next wave of research that hopefully will help us to elucidate the brain and body mechanisms involved in the genesis of major psychiatric illnesses – with an ultimate goal of generating novel, more impactful treatment targets.'
