A non-invasive manner refers to a method or procedure that does not require the insertion of instruments or the breaking of the skin to gather information or perform a task. In the context of understanding the brain, it means studying its structure and function without physically entering the brain.
This imaging technique uses strong magnetic fields and radio waves to generate detailed images of the brain's structure and function.
Electroencephalography (EEG): It measures electrical activity in different areas of the brain by placing electrodes on the scalp. It is non-invasive as it only records external signals produced by brain activity.
Functional Magnetic Resonance Imaging (fMRI): Similar to MRI, but specifically focuses on changes in blood flow within different parts of the brain, providing insights into its functional activity.
