✓Well SupportedElectrodes inserted directly into the brain offer higher resolution for recording single neuron activity compared to ECoG.✓Well SupportedRecording directly from single neurons offers a resolution approximately 5,000 to 6,000 times better than scalp EEG.✓Well SupportedBrain-computer interfaces can extract speech signals from the brain to potentially restore communication for individuals with motor system impairments.◐Partially SupportedPlacing electrodes on the brain cortex surface without penetrating the pial membrane can avoid immune reactions and scarring.◐Partially SupportedThe skull and scalp significantly attenuate and diffuse brain signals, making precise interpretation from scalp EEG almost impossible.

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

◐Partially SupportedNeuroengineering uses computers and sensors to interpret neural signaling to guide more normal signaling.

◐Partially SupportedIn brain areas with intermixed information, neural tuning changes may necessitate recalibrating decoding algorithms every few hours or days.

◐Partially SupportedElectrical activity from neurons, specifically action potential propagation, underlies thoughts, communication, and motor functions.

◐Partially SupportedCurrent prototype BCI systems using percutaneous ports have infection risks, driving the field towards fully implantable, wireless technologies.

◐Partially SupportedBrain-computer interface applications include controlling a computer cursor or replacing speech for severely paralyzed individuals.

◐Partially SupportedEEG is a non-invasive brain signal recording method using scalp sensors.

◐Partially SupportedBrain-computer interfaces (BCIs) involve recording brain signals, analyzing them with a computer, and using the analyzed signal to perform an action.

◐Partially SupportedPatients with severe paralysis and aphasia, such as those with ALS, may have normal cognition but cannot motorically produce speech.

◐Partially SupportedECoG devices can be used to help people with seizures by recording brain activity and stimulating to stop seizures.
