Scans are organized into what are called "biosurveys".  

You’ve probably  filled out a survey before, a series of questions to which you provide answers.  A biosurvey is essentially the same thing, only you don’t  answer the “questions” consciously — your body answers them directly.

With ZYTO biocommunication, the “questions” is the Virtual Item, The  answer, a change in the electrical properties of your skin is recorded  and analyzed by the ZYTO decision support software.

A biosurvey can be as varied and versatile as any other survey.  Some  biosurveys are general in nature and include Virtual Items concerned  with overall wellness, while others include Virtual Items relating to  specific areas of the body or body systems. There are also biosurveys  that deal with environmental factors.

Here are the basic concepts and processes of a ZYTO biocommunication scan, or Bioscan.

1) Galvanic Skin Response:  The ZYTO bioscan relies on galvanic skin response (GSR)—an  established technology that measures fluctuations in electrical  conductivity of the skin. One familiar application of GSR is lie  detector testing. 

2) ZYTO Hand Cradle:  The ZYTO Hand Cradle measures the user’s galvanic skin response and  sends that data directly to the ZYTO software for analysis. The GSR data  is correlated and compared with Virtual Items in the software database. 

3) Virtual Items:  Each Virtual Item represents a different physical item. Every time  the software introduces a Virtual Item, a corresponding GSR reading is  taken by the Hand Cradle. Each new response is measured and tracked in  comparison to the GSR baseline reading. 

4) Proprietary Software:  ZYTO’s proprietary software analyzes GSR data for patterns of  coherence—looking for the ways your GSR readings fluctuate or shift in  response to each Virtual Item. 

5) Biological Coherence:  While tracking the GSR data in comparison with each Virtual Item,  ZYTO software assigns each Virtual Item a positive or negative value  based on the coherence patterns. Positive values indicate Virtual Items  that the body is biologically coherent with. 

6) Prioritized Responses:  An easy-to-read report is generated that displays a ranking of the  Virtual Items that resulted in greater biological coherence. The report  can then be used to assist individuals as they make choices to maintain  overall health and wellness. We call this whole process  biocommunication.
