1. A neurostimulation and neurorecording interface control circuit, comprising:
a stimulation terminal;
a recording terminal; and
an interface control subsystem in electrical communication with the stimulation terminal and the recording terminal and disposed between the stimulation terminal and the recording terminal, the interface control subsystem configured to operate in:
a disable mode in which the neurostimulation and neurorecording interface control circuit is configured to provide a high impedance between the stimulation terminal and the recording terminal;
an active mode in which the neurostimulation and neurorecording interface control circuit is configured to provide a low impedance between the stimulation terminal and the recording terminal; and
a stimulation mode in which the neurostimulation and neurorecording interface control circuit is configured to provide an impedance between the high impedance of the disable mode and the low impedance of the active mode.
