EPSP Slope
The slope is calculated by using a linear regression line of the data points in the 10 % to 90 %
(or 30 % to 70 %) interval of the first EPSP amplitude (stretching from extremum to baseline)
in the region of interest. The slope of the resulting straight line is extracted as the EPSP
slope value. The EPSP Slope value is in units of V/s.
Corresponding Parameter for Paired Pulse Pattern
It is possible to analyze and display the parameters explained above for paired pulses respectively.
The principle of signal detection is not modified. As usual PS = population spikes are somatic
signals , and EPSP = excitatory postsynaptic potential are dendritic signals.
