Hi all,
I am new to electrophysiology, and I have some inqueries about current-voltage relationship.
Why some authors plot both I-V relationship and I/Imax-V relationship. What is the difference between them?? And why they sometimes show some differences in statistical analysis and/or significance at some potentials when comparing the different treated groups ? For example,.there may be sigificance in I-V plot between gpA and B which disappear in I/Imax-V
2. How can I know that a drug has reached its steady-state of action for example; AICAR.
Dear Esraa Said,
When one plots the absolute value of I versus V will be different from one plots the normalized value of I versus V. The normalization expresses the profile of the curve such that one can compare the different cases according to the shape of their profiles. Absolute current values contain more information about the speed of the process. Which may be due to larger area of the electrodes for example.
This is a generic answer for your question. This is process of scaling is called normalization.
Best wishes
Please note that dividing by the maximum value is normalizing.
I-V curves is the transfer characteristic in BJT or MOS as an example.
To find these curves please look at my book
