The goals that this thesis work wants to achieve are two: one objective is to redact a schematic review of the Readiness Potential, the components it is made of (early BP, late BP and also LRP) and the factors modulating its waveform; the other is to write a program that performs onsets and amplitudes measurements using methods found in literature and to compare these results to observe the robustness of the different algorithms. These methods include peak and mean amplitude measurements using different parameters, as well as many onsets measurements, divided in criterion-based, baseline-based and regression-based methods. To understand the robustness of these techniques we divided our dataset in three categories: high-quality, medium-quality and low-quality data.
