Electroencephalogram (EEG):A technique that measures the electrical activity of large groups of neurons in the brain using electrodes placed on the scalp.
Functional Magnetic Resonance Imaging (fMRI): A method that uses magnetic fields to measure changes in blood flow in the brain, providing insight into which areas are active during specific tasks or stimuli.
Single-Neuron Recording: An invasive technique where thin electrodes are inserted into an individual neuron to directly record its electrical activity.
