1. A neurological electrode system, comprising:
a magnetic resonance environment with a radio frequency (RF) field;
an electrode for neurological monitoring;
a connector configured to connect to an amplifier;
a cable, having a first end and a second end, the first end in electrical connection to the electrode, the second end in electrical connection to the connector; and
an inline filter module configured along the cable, the inline filter module comprising one or more inductors and one or more resistors in series, wherein total resistance of the one or more resistors is below 1 ohm, wherein the inductors and resistors are configured in the inline filter module to reduce radio frequency power in the electrode system and the inline filter module limits heat generation in the electrode.
