In this research the pain response of 6 healthy participants is studied using an electroencephalographic device. To have a first approach to the problem and a clearer understanding of the pain response, a non-traumatic thermal stimuli is used, which simulates phasic pain that is known for being gradual. The use of machine learning is important to find a discrimination model among 3 conditions proposed (pre-stimulus, beginning of the stimuli and intolerance to the stimuli) and the EEG data recorded. Different machine learning models found a solid distinction between the 3 different conditions in the case of the 4 males. Females could not be classified since the stimulus does not generate any kind of pain to them.
