Scientific Approaches and Technologies


The following collection of the latest technologies is available for the mind/body research of our Laboratory.


I. Instruments for Physiological Measurements




  • Holter-type Monitor Systems

    • Portable Holter-type monitors (made by PI Instruments, China ) are used to record electrocardiograms (EKG/ECG) for Heart Rate Variability Analysis (HRV, a indication of autonomic function), electroencephalograms (EEG, for analysis of brain wave intensity and pattern), and electromyograms (EMG, for monitoring muscular activity).  The recorded data sets are then downloaded into a computer, which contains software for Fast Fourier Transformation spectral analysis. 


  • Laser Doppler Flowmetry

    • The laser Doppler instrument (Moor

       Instruments, Ltd., U.K. ) has two separate probes with integrated temperature sensors for continuous measurement of temperature and the flux, concentration, and velocity of red cells in cutaneous blood flow. 


  • Spirometer

    • An electronic spirometer connected to a computer (Spider 5 from Micro Medical Co., U.K. ) is used to quantify the rate and tidal volume of breathing cycles.

  • Blood Pressure Monitor

    • Blood pressure is measured at the wrist with a portable electronic monitor.





II.   Emerging Biomedical Technologies


  • Independent Component Analysis of EEG

    • Advanced EEG recording is made with a 128-channel system (Geodesic Sensor Net System made by Electrical Geodesic, Inc., U.S. ) in Dr. Ramesh Srinivasanís Laboratory in UCIís Department of Cognitive Science. Independent Component Analysis of the data is subsequently performed by Dr. Tzyy-Ping Jung at the Schwartz Center for Computational Neuroscience of the University of California , San Diego . This type of advanced computerize analysis enables us to objectively identify and localize brain wave patterns specific to mind/body activities, and to determine the 3-dimensional location of the signal generators inside the brain.


  • Photon Migration Spectroscopy

    • Transdermal and transcraniel measurements of oxyhemoglobin concentration and oxygen consumption rate in different parts of the brain and/or the body are made with a Dual-channel Oxiplex TS Instrument (from ISS, Inc., U.S. ) by Drs. Enrico Gratton and Antonios Michalos of the Fluorescence Dynamics Laboratory at UCI.




III.  Technologies for Bioenergy Measurements.


  • Infra Red Thermography

    • The portable camera system (ThermoVision A20M-FireWire Infrared Imaging System from Flir Systems, Inc., Sweden), with sensitivity of 0.1o C, has a zoom lens that can capture single images or a video sequence of targets of various sizes, ranging from a single spot to the entire body.  The analysis software (ThermoCAM Researcher Pro) allows the choice of size and shape of the area to be measured in the images stored in the computer, and the comparison of values from different areas.


  • Single Photon Counting System

    • A Single Photon Counting System has been assembled in the Laboratory by Dr. Gaetan Chevalier, using an Integrated Counting Head with sensitivity to visible light of 300-650 nm (Model H59020-01 from Hamamatsu Corp. Japan), a Linear Power Supply (Model LPS-304/CE, from AMRE, USA), and a Timer/Counter/Analyzer (Model PM6680B/016, from Fluke, The Netherlands).  Biophoton emission from the palm is measured by placing the hand at a fixed distance in front of the counting head, which is located inside a temperature-controlled and light-proof chamber with a covered opening.  The data from the counter are inputted into a computer and analyzed with the TimeView software.


  • Gas Discharge Visualization (Digital Kirlian Photography)

    • Emission of electrons induced by a short pulse of high voltage field at the finger tip is detected by Gas Discharge Visualization with a Camera Pro GDV system (from KTI, Russia ).  The digital images are inputted into a computer and analyzed for area, brightness, form coefficient, fractility, entropy, etc.



  • Single Square Voltage Pulse Method

    • The Single Square Voltage Pulse instrument (AMI, made by AMICS, Japan) is used to measure pre- and post-polarization conductance at 24 acupuncture points located at the terminals of the major meridians located at the tips of fingers and toes (i.e., jing-well points of left and right meridians for heart, liver, spleen, lung, kidney, small intestine, large intestine, gall bladder, urinary bladder, stomach, triple heater, and pericardium).  The two types of conductance measurements are believed to be indicative of the energy or stress of the meridians and their associated organs, respectively.  The values can be analyzed separately, in sub-groups (i.e., left vs. right, upper body vs. lower body, yin vs. yang organs), or as an averaged overall value indicating the general state of health.
