AcqKnowledge 3.8.2 and above for Windows allows you to synchronize video files with physiological data. This allows you to jump to specific points in either the video or data file, and the corresponding data or video will jump to the correct time point. If you use a visual presentation system such as SuperLab, you can jump to the event markers in the data file and view the corresponding video.
Use an OUT103 LED cable to synchronize the video camera to the MP System. OUT103 connects to one of the analog output connectors on the bottom front UIM100C or the digital connectors on the back (for an MP150 system, the UIM will have to be separated at the MP150 side of the device to allow access to the heads of the screw terminals). To use OUT103 with an MP36R unit, add a BSLCBL6 interface cable and OUT3 adapter. In the software menu, under MP1XX>Setup Stimulator (in AcqKnowledge 4.4, choose “Stimulator” in the pane on the left after selecting “MP150 > Set Up Data Acquisition…”), use the stimulator settings to turn on the LED when the MP system starts recording data. Make sure that the video camera is recording and place the LED somewhere in view of the camera so that when you start recording you will see the LED turn on. When you review the video, you will see the LED turn on and that marks the start of the data acquisition. Use the timing measurements in AcqKnowledge to synchronize the video and data files.
fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). They provide an in-lab cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. fNIR optical imaging technology measures neural activity and hemodynamic response in the prefrontal cortex. Subjects wear an fNIR sensor (IR light sources […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies covering HRV, EMG, and EEG measurement. HRV (Jing Wei, Hong Luo, Si J. Wu, Paul P. Zheng, Genyue Fu, and Kang Lee) Humans encounter various stressful situations everyday at work, home, and school. Such stress when experienced at high degrees and/or […]
Alan Macy Answers Proust Questionnaire BIOPAC co-founder and R&D Director, Alan Macy, was interviewed recently by Roger Durling for the Santa Barbara Independent. The article, “The S.B. Questionnaire: Alan Macy,” provided a background excerpt of the Santa Barbara entrepreneurs’ past as well as his answers to the Proust Questionnaire. The biomedical technology developed at BIOPAC reflects an ambitious […]
