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 + STMISOLA 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.
BIOPAC is introducing Biopac Student Lab Home (BSL HOME)—a new product specifically geared towards teaching physiology labs remotely so students can still get hands-on, practical lab experience if social distancing and stay-at-home orders keep them out of the lab..
BSL HOME will allow your students to conduct physiology labs in the safety of their own home, dorm room, or any remote location.

Comparing Muscle Movement and Involvement between Boxing Punches In the fast-paced, high-intensity combat sport of boxing, the right punch can win a fight. However, boxing is also a sport where opponents can become exhausted in mere minutes of action, and prioritizing their strength is key to winning a fight. This team recorded EMG on test […]
