1. A device comprising:
a housing configured to be subcutaneously implanted at a portion of a neck or a head of a patient;
at least three electrodes comprising a first pair of electrodes configured to sense a first differential signal and a second pair of electrodes configured to sense a second differential signal, the at least three electrodes positioned on the housing;
circuitry configured to:
generate a first cardiac signal based on the first differential signal sensed via the first pair;
generate a first brain signal based on the first differential signal sensed via the first pair;
generate a second cardiac signal based on the second differential signal sensed via the second pair;
generate a second brain signal based on the second differential signal sensed via the second pair;
output a composite cardiac signal based on the first cardiac signal and the second cardiac signal; and
output a composite brain signal based on the first brain signal and the second brain signal,
wherein the first cardiac signal comprises a first electrocardiogram (ECG) signal, the second cardiac signal comprises a second ECG signal, the first brain signal comprises a first electroencephalogram (EEG) signal, and the second brain signal comprises a second EEG signal.
