| Objective: To observe the effect of multi-module 3D-VR memory-related training on brain function activation by functional near infrared spectroscopy (fNIRS). Methods: A total of 26 healthy subjects were recruited in this experiment, and each of them tried a 15-min multi-module 3D-VR memory-related training. All subjects were monitored by resting fNIRS for 10 min before and after the training. The frontal lobe blood oxygen signals were collected from all channels in the two tests, the beat value of frontal lobe blood oxygen concentration and the average value of blood oxygen signals were recorded, and the changes of frontal lobe function and its influence on cortical activation were compared and analyzed. Results: Compared with those before the test, the beta values of OXY-HB in frontal lobe in channels (14, 22, 24, 43) were significantly different (P<0.05), and the mean values of blood oxygen signals in frontal lobe in channels (14, 22, 24, 43) were significantly different (P<0.05). Conclusion: Multi-module 3D-VR memory-related training can significantly activate the left middle frontal gyrus, the left medial frontal gyrus, the left dorsolateral frontal gyrus and the right middle frontal gyrus (channels 14, 22, 24 and 43), and the above cognitive related brain regions such as attention and memory. |
