And why not using EPSP amplitude ? When they measure LTP they always use EPSP slope why is that and what is it ? Also what is EPSP spike compared to amplitude and slope ?

Thanks'

it is more convincing to show both, amplitude and slope, because each parameter can change independenty from the other but in the case of LTP both should be increased

The EPSP slope in an extracellular field recording is usually taken as the first one-third of the fEPSP. The slope value is preferred over the amplitude or other measures because at a higer current intensity (or if the electrodes are places too close to the cell bodies), the pEPSP is likely to be contaminated by the occurance of a pop spike and that can change the amplitude but not the slope.
