Neuroscience is an interdisciplinary area, which builds and interacts with other fields such as psychology, computer science, psychoneuroimmunology, neuroendocrinology, and genetics, to study the structure, development, and functioning of the nervous system and the brain. It involves a diverse set of techniques, such as brain imaging and genetic mapping, and draws on different sources of information, such as animal models and computer simulations. All of these tools can be used to improve the understanding of the role that anatomy, physiology, biochemistry, and the molecular biology of nerves and nerve tissue play in human behavior and experience in general and attachment dynamics in particular. We refer to these approach as “neuroscience” for simplicity, but to be clear, we will focus in the chapter on a wide gamut of physiological indexes, as well as genetics, endocrinology, and immunology.
