LOOKING INSIDE THE BRAIN: An overview of Brain Scanning / Investigation techniques
Cardiff University Psychology・2 minutes read
The text discusses different brain investigation techniques, such as structural, functional, and brain stimulation techniques, each serving unique purposes in understanding brain activity, like imaging internal brain structures or monitoring real-time brain function. These techniques include CT scans, fMRI, and EEG, each providing different insights into brain activity and function.
Insights
- Structural brain investigation techniques like CT scans provide detailed images of internal brain structures, similar to taking photographs of a car engine's components.
- Functional brain investigation techniques such as fMRI and PET scans offer real-time insights into brain activity by detecting changes in blood flow or biological properties, providing valuable information on brain function.

Brain Investigation Techniques: Understanding Brain Activity Through Imaging
- Brain investigation techniques can be categorized into structural, functional, and brain stimulation techniques, each serving different purposes in understanding brain activity.
- Structural techniques, like CT scans, provide detailed images of the brain's internal structures, akin to taking photos of a car engine's components.
- Functional techniques, such as fMRI and PET scans, reveal real-time brain activity by detecting changes in blood flow or biological properties, offering insights into brain function.
- EEG and MEG measure electrical and magnetic brain signals, respectively, with EEG having good temporal resolution but poor spatial resolution, while MEG excels in localizing brain activity.
- Brain stimulation techniques, like TMS and tES, involve sending signals into the brain to affect its function, allowing researchers to establish causality in brain region functions, unlike functional imaging techniques.
