This analysis computes the volume of electrically participating tissue (VEPT) in cubic centimeters of a subject using the truncated cone method. It can be used to calculate VEPT independent of…
For caloric induced nystagmus, synchronize the vestibular stimulation with the nystagmus recording to obtain precise nystagmus latency. For rotationally induced nystagmus, use the wireless BioNomadix system to record the EOG to…
Capture muscle force data in real time. Features include improved reproducability between subjects, reduced setup time, no skin prep, and no electrodes.
fNIR functional near infrared systems for optical brain imaging can interface with the BIOPAC virtual reality platform. BIOPAC VR provides controlled and replicable experimental setups and allows manipulation of the…
To perform Visual Evoked Response (VER) and Flash Visual Evoked Potential (FVEP) studies, use the TSD122 Stroboscope and the averaging mode in AcqKnowledge. The stroboscope will trigger the MP System…
MP Systems with an STP100C module can interface with most major visual presentation programs, including: SuperLab® (see STP100W), E-Prime®, DirectRT®, MediaLab®, Inquisit®, and Presentation® for a variety of visual evoked…
Vibromyography (VMG) has distinct benefits over EMG in that the recordings much more accurately reflect absolute muscle effort up to 100% maximum voluntary contraction. Correspondingly, VMG can be used to…
The ability to noninvasively assess voluntary muscle effort has wide application in physiologic studies, sports and rehabilitation medicine, as well as movement science. Traditionally, surface electromyography (sEMG) has been used…
Vibromyography (VMG) has distinct benefits over dynamometry in that VMG recordings reproducibly reflect absolute muscle effort up to 100% of maximum voluntary contraction. Correspondingly, VMG can be used to simultaneously…
To date it has been difficult to characterize the length-tension curve for a specific muscle. However, recent developments in the application of vibromyographic (VMG) technology to assess muscle effort permit…
Easily compare normal tidal breathing loops to maximum breathing loops by using the X/Y mode to plot flow versus volume in realtime and post acquisition. It’s possible to control the…
Usage Guidelines This demo is also intended to serve as a tutorial on how to construct a virtual reality experiment. It can be fully modified and has been designed in…
In this demo, the participant is exposed to a sequence of rooms along a corridor that contain different stimulation environments. Four neutral environments and four smoking environments are included.
3D model library Models can be used within the VR platform only.
In this demo, the participant is seated in an airplane and experiences normal flight, turbulence, and landing. Tactile feedback is employed to increase the experience of presence. Usage Guidelines This…
In this demo, participants follow the Iowa Gambling Task, a classic experiment in which participants choose between decks of cards with different payoffs. The skin conductance response before and after…
In this demo, a social anxiety scenario, the participant delivers a speech in front of an audience. The audience attitude can be varied by the experimenter between different states (e.g.,…
The Vizard VR Toolkit (developer edition) is included in all workstations Use the VR Toolkit virtual reality interface software with your BIOPAC data acquisition and analysis system to synchronize events from…
Water Content Measurement and Adiposity is an area of active research and so specific methods of performing total body water (TBW) measurements using BIA may change. The following formula is…
BIOPAC is the worldwide distributor for Advanced Brain Monitoring’s B-Alert product line. The B-Alert wireless EEG system operates as a stand-alone wireless EEG system or interfaces with BIOPAC’s range of…
