Motor Imagery BCI

Low-Pass Filter A device or algorithm that only allows the low-frequency component of the signal to pass through and attenuates the high-frequency component of the signal. E.g., RC LP Filter: a capacitor blocks DC and passes AC voltage. Usage: High-Pass Filter: A device or algorithm that only allows the high-frequency component of the signal to […]

What is BCI? (Brain computer interface) Interface → communication pathway BCI → The system that provides a communication pathway to convert brain activity signals to instructions recognisable to computers. Process of basic BCI systems: Characteristics of EEG: EEG signals originate from the potential changes caused by the discharge of neuron populations and are measured by scalp surface electrodes. Pros: […]
