13. Kernels v/s Responses and some New Developments in VERIS 6 The m-sequence technique provides a series of kernels. Most of us do not have an intuitive understanding of these mathematical constructs. However, from them we can easily predict the results of many experiments such as double and multi-flash tests from a single m-sequence stimulus series. This is illustrated in the following few slides that are derived from a single record of 54 seconds duration using m-sequence Ganzfeld flash stimulation. Ask for a Demo with VERIS!
