Embodiment Construction

[0019] The technical solution proposed by the present invention will be described in further detail below with reference to the accompanying drawings.

[0020] Such as figure 1 As shown, a near-infrared brain imaging atlas acquisition method based on cognitive tasks provided by the present invention includes:

[0021] The first step S1, connect the near-infrared brain imager to the subject's brain;

[0022] The second step S2, at T 1 Sequentially provided to subjects within the time interval for a duration of T 2 The first cognitive task, the second cognitive task, and the third cognitive task of, specifically, in the present invention, the first cognitive task, the second cognitive task, and the third cognitive task are selected from language One of the fluency task, the pointing motor task, and the symptom picture task. And, preferably, in the second step, before performing the first cognitive task, a fourth cognitive task is further included, and the fourth cognitive task is an e...

Abstract

The invention discloses a near-infrared brain imager map collecting method based on cognitive tasks. The method comprises steps as follows: step one, a near-infrared brain imager is connected to the brain of a subject; step two, a first cognitive task, a second cognitive task and a third cognitive task with duration time of T2 are provided for the subject sequentially at time intervals of T1; step three, near-infrared brain imaging maps of the brain of the subject are continuously collected in the time period of T2, wherein T1 is not equal to T2. According to the near-infrared brain imager map collecting method based on the cognitive tasks, under the stimulus presentation of the cognitive tasks, the near-infrared brain imaging maps which are easy to recognize are acquired, and related research workers can perform further quantitative statistics on characteristic waveforms in the maps conveniently and further guide follow-up work.

Description

Technical field [0001] The invention relates to an atlas acquisition method, in particular to a near-infrared brain imaging atlas acquisition method based on cognitive tasks. Background technique [0002] At present, the near-infrared functional brain imaging technology (fNIRS) is an emerging method of brain function activity monitoring, which uses the good permeability of near-infrared light to human tissues to detect the characteristics of blood flow changes in related brain regions. Compared with other brain imaging technologies, fNIRS is more and more favored by psychologists due to its high safety, high ecological validity, and relatively high spatial and temporal accuracy. [0003] It is now known that depression and anxiety are closely related to cognitive processes, but the specific connection is still not very clear. But it is conceivable that this technology will be very helpful in identifying the cognitive performance characteristics associated with depression, anxiety,...
