We have acquired a strong experience in the use of infrared lasers as nociceptive stimulators. At present, we are involved in the conception and construction of a novel infrared stimulator based on a feedback-controlled CO2 laser (Figure 1). The new device will provide a precise and dynamical control over the delivered nociceptive stimuli. In addition, the laboratory has dedicated a significant part of its resources to the development of novel techniques to analyse EEG signals. The tools developed have been progressively incorporated in a comprehensive signal-processing library which has been made available to several research centres.
