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.
Stim-Response | Virtual Reality - Synchronize events from a virtual world with physiological data from an MP150 system. Use feedback loops for greater control and automation—change the VR world in real time.
Eyes are the window to the soul and, more importantly, the brain. Psychophysiology, neuroscience, and consumer neuroscience researchers use eye tracking technology to understand emotion, behavior, subject response, decision-making, and human performance—and to help improve products and services. But not everyone knows where to start or how and why to use this important technology. A panel of eye tracking experts will present typical use cases and the latest eye tracking technology.

Solving Physical Stress Issues for Surgeons Physical stress in the operating room is common for surgeons, considering how much time they spend in an upright standing position during surgical procedures. With procedures that require standing for several hours and average reported working times of 60-80 hours a week, surgeons seem to be at risk for musculoskeletal […]
