Abstract (2. Language): 
Pain related evoked potentials stimulated by laser. It became possible to record brain responses evoked by painful stimuli with the use of the laser stimulators which produce pain selectively. To obtain Pain Related Potentials (PRP), we used a diod laser of 980 nm vvavelength. Stimuli were applied to the dorsum of the right hand of 10 volunteer subjects. Stimulus duration was set to 200 ms and intensity was set to % 50 higher that the pain threshold. The EEG signals were collected from Fz, Cz, Pz, C3 and C4 locations according to international 10/20 system. Thirty stimuli were given with random interstimulus interval changing betvveen 5 and 9 secs. The latencies and the amplitudes of the potentials were measured on the averaged responses and the grand averages were calculated.

Ağrı ortaya çıkaran bir uyarana karşı oluşan uyarılmış potansiyellerin elektrofizyolojik olarak kaydı, spesifik olarak sadece ağrı duyusu oluşturan laser stimülatörlerin kullanımı ile mümkün olmaktadır. Ağrı ile ilişkili uyarılmış potansiyel (Pain Related Evoked Potentials = PRP) kaydı için 980 nm dalga boyunda ışın çıkaran diyot laseri kullanılarak, 10 sağlıklı, gönüllü deneğin sağ el sırtına, 200 ms süreyle, ağrı eşiğinin 1.5 katı şiddetinde, rastlantısal olarak 5-9 saniye aralıklarla 30 uyaran verilerek, uluslararası 10-20 sistemine göre Fz, Cz, Pz, C3 ve C4 bölgelerinden kayıt alındı. Elde edilen yanıtlar averajlandı, ölçülen latans ve genlik değerlerinin ortalamaları hesaplandı.
