Neuroimaging

Definition

Neuroimaging refers to a set of techniques that visualize the structure and function of the brain. These methods, which include techniques like MRI, fMRI, PET scans, and CT scans, allow researchers and clinicians to observe brain activity, identify structural abnormalities, and understand how different areas of the brain interact. This technology is crucial in studying various aspects of the brain, such as the endocannabinoid system's functions and the development of personalized medicine in psychopharmacology.
