There are many available tools for capturing information about brain function and structure in children. Investigating brain function and structure helps us understand the neurobiological factors that contribute to current or later psychopathology risk. (e.g., Pinkham et al., 2008). Magnetic resonance imaging (MRI) is a technique that is widely used because it is non‐invasive and can capture properties about brain structure and function at all ages, even prenatally (Peterson, 2003). Structural MRI studies inform about brain anatomy and are used to examine the volume and shape of brain regions. Functional MRI (fMRI) studies provide information about activation in the brain, often in key regions, during rest or during specific tasks that require basic cognitive or emotional functioning. Electroencephalography (EEG) and magnoencephalography (MEG) are techniques that allow for the non‐invasive assessment of brain function. EEG and MEG provide highly accurate measurements of the timing of neural responses, but there is less spatial precision. Each neuroimaging technique offers specific advantages and disadvantages for studying neurobiological functioning across development.
