| CNV / LRP measurement |
Below you find an example of an CNV/LRP (Contingent Negative Variation / Lateralized Readiness Potential) measurement done with the ActiveTwo. CNV/LRP measurements are event-related brain potentials that are associated with motor preparation processes. |
|
| This picture shows the unique ability of the ActiveTwo to record extremely small low frequency signals without any skin preparation. A recording like this is only possible with a DC amplifier and active electrodes. The Figure contains CNV / LRP data recorded in a S1-S2 paradigm with a 1,200 ms foreperiod. This shows that the ActiveTwo system works nicely with these paradigms. Also other measurements have been done with longer foreperiods (2.5 sec). | |
| These measurements have been done at the University of Glasgow by Dr Hartmut Leuthold and Dr Ines Jentzsch. | |
