Example methods disclosed herein include evaluating a first property of a first neurological signal, determining if the first neurological signal complies with a quality threshold based on the first property, evaluating a second property of a second neurological signal and determining if the second neurological signal complies with the quality threshold based on the second property. The example methods also include conditioning the first neurological signal if the first neurological signal does not comply with the quality threshold to obtain a third neurological signal and conditioning the second neurological signal if the second neurological signal does not comply with the quality threshold to obtain a fourth neurological signal. In addition, the example methods include evaluating a third property of the third neurological signal, and evaluating a fourth property of the fourth neurological signal and determining if the fourth neurological signal complies with the quality threshold based on the fourth property.
