A generous financial donation to our institute enabled us to purchase a near infrared spectroscope (NIRS) produced by Artinis company. Figure 1 shows on the left side the NIRS device incorporated into a head band and attached to a model head for simultaneous registration of brain oxygen supply and blood flow of left and right frontal brain lobe. The model head on the right side wears an EEG cap for simultaneous recording of electrical brain activity and NIRS signals. Figure 2 shows from top to bottom the time course in seconds (Time (s)) of deoxygenated blood (HHb, blue), oxygenated blood (O2Hb, red) and total blood flow (tHb, black) during listening to music (black bar, music). The curves with bold colours are recorded from the right and curves with pale colours from the left frontal brain lobe of a test person. OD characterizes the degree of the NIRS signal. During listening to music O2Hb increases due to increased cellular oxygen need stronger in the left than in the right frontal lobe. After finishing music O2Hb decreases whereas HHb increases due to increased brain oxygen consumption again stronger in the left than in the right frontal lobe. The total blood flow of the frontal lobes is increased during the music period without regional differences.
