Non-invasive BCIs typically use which technique to record brain activity?
- Electrocorticography (ECoG)
- Electroencephalography (EEG)
- Functional MRI
- Magnetoencephalography (MEG)
Answer: Electroencephalography (EEG)
EEG places electrodes on scalp to detect electrical activity from neuronal populations. Portable, low-cost, real-time; used in neurofeedback, prosthetics control, communication aids for locked-in patients. [[NCERT Biology Class 11, DBT Reports]]
