As a result, the bulk of literature in behavioral neuroscience deals with experiences and mental processes that are shared across different animal models such as: Sensation and perception; Motivated behavior (hunger, thirst, sex) Control of movement; Learning and memory; Sleep and biological rhythms; Emotion
Type 1 diabetes is a result of the destruction of pancreatic beta cells, although what triggers that destruction remains unclear. [75] People with type 1 diabetes tend to have more CD8+ T-cells and B-cells that specifically target islet antigens than those without type 1 diabetes, suggesting a role for the adaptive immune system in beta cell ...
