Measuring electrical activity refers to the process of recording and quantifying the electrical signals produced by neurons in the brain. It helps researchers understand brain function and identify abnormalities.
A tool used to measure the electrical activity in the brain through electrodes placed on the scalp.
Magnetoencephalography (MEG): A technique that measures magnetic fields generated by neuronal activity to map brain functions with high temporal resolution.
Functional Magnetic Resonance Imaging (fMRI): A method that uses changes in blood oxygenation levels to detect neural activity and create detailed images of brain structures and functions.
