This Application Note details various protocols for identifying a stimulation threshold for stimulation. The purpose of establishing this threshold is to ensure the subject’s comfort level and safely determine the point at which a stimulation signal becomes unpleasant, or even painful. This is accomplished by sending a series of very short stimulus pulses to the subject and gradually increasing the voltage. The subject then indicates his or her level of comfort or discomfort, and the stimulation is adjusted accordingly.
Case 1: MP150 + UIM100C + STM100C + STMISOLA (current and voltage mode) or STMISOC/D/E (voltage mode only) + LEAD110A x2 + EL509 + GEL104 Case 1a: MP160 + HLT100C + STM100C + STMISLOA or STMISOC/D/E + LEAD110A x2 + EL509 + GEL104
Case 2a: MP150 + UIM100C + STM200 + LEAD110A x2 + EL509 + GEL104 Case 2b: 3rd-party hardware and software + STM200 + LEAD110A x2 + EL509 + GEL104
Case 3: E-Prime + STMISOLA or STMISOC + LEAD110A x2 + EL509 + GEL104
ERS: Evoked Response - Record evoked, late, and field potentials, as well as startle and nerve conduction. Powerful on- and off-line averaging features (P300), and dual stimulation ability with the MP150.
Psychophysiology - Record and analyze BP, ECG, HRV, EDA, EMG, EEG, EOG, RSP, etc. Interface to stimulus presentation programs...use automated analysis routines to easily score and analyze data.
