Problems solved by technology

However, there are cases where appropriate results cannot be obtained using the above-mentioned unstable data
Further, there is a problem that a time difference is generated during measurement and the state of the subject is changed by performing the quiet question and the stimulating question separately
[0012] In Patent Document 1, the next presented stimulus is changed according to the subject's response, but the stability of the subject's state, that is, the stability of the quiet topic, is not considered sufficiently.

Embodiment 1

[0049] figure 1 It is a functional block diagram showing a first embodiment in which a stimulus task presenting device is assembled in an in vivo optical measurement device (optical drawing device) of the present invention, figure 2is a schematic diagram of the measurement scene of the measurement device of this embodiment. The device of this embodiment is composed of the following components: a stimulus topic presentation control unit 100, which performs processing such as manual generation, presentation, and analysis of stimulus topics; a stimulus presentation unit 110, which performs stimulus presentation through a monitoring screen of the subject; The microphone 112 and the button 114 of the responding unit of the subject; and the display unit 120 display the processing results and the like of the stimulus item presentation control unit 100 to the measurer. The output of the optical mapping device 130 for measuring brain function is also displayed on the display unit 120...

Embodiment 2

[0082] Referring to Figure 10 ( Figure 10A , Figure 10B ) illustrate other embodiments of the present invention. In these examples, the introduction and content of the quiet question and the stimulating question are sequentially changed according to the measurement results. first, Figure 10A An example is to delete a question block indicating an inappropriate response based on the overall average (in the question) value displayed on the display unit 120 of the stimulus question presentation control unit 100 . That is, by the same method as that described in Example 1, during the measurement, the subjects were repeatedly and repeatedly executed the quiet topic (quiet 1, quiet 2, quiet 3) and the stimulating topic (topic 1, topic 2, topic 3) every 60 seconds. 3) Confirm the obtained data sequentially on the display unit 120 of the stimulus task presentation control unit 100 . As a result, for example, in the block of Question 2, the number of responses of the subject is a...

Embodiment 3

[0085] refer to Figure 11 A third embodiment of the state stability at the time of the quiet task of the present invention will be described.

[0086] Figure 11 A flow chart showing stimulus task presentation that realizes "state stability during resting task" in the third embodiment of the present invention. The difference with Embodiment 1 is that before switching to the stimulating question, the quiet question is repeated for a predetermined number of times, for example, 3 times. In this repeated course, it is judged whether the quiet question needs to be changed according to the state of the stability of the test object (S540 ), when it is determined that the stability is low and needs to be changed, the quiet topic is changed to a simpler topic than the standard topic (S542). For example, the interval of the presentation time of the topic is extended. In this way, appropriate treatment for tranquilization can be performed according to the state of the subject.

Abstract

A load of a stimulating task on an examinee with a resting task being unstable is excluded, and an accurate answer of an examinee to presentation of a stimulating task is enabled. A stimulating task presentation device in a living body optical measurement device includes a stimulation presenting unit configured to present a stimulation to an examinee, a brain function measurement device for measuring a brain function of the examinee in parallel to presentation of the stimulation, and a stimulation presentation controller configured to control the stimulation presented by the stimulation presenting unit, and the stimulation presentation controller has a function of setting a resting task and a stimulating task to be presented to the examinee, a function of detecting an answer of the examinee to the resting task and the stimulating task, and a task presentation control function of determining the degree of stability on the basis of the detection result when the resting task is presented, and controlling presentation of the resting task or the stimulating task on the basis of the degree of stability.

Description

technical field [0001] The invention relates to a stimulation topic presentation device and a stimulation topic presentation method in a living body optical measurement device. Background technique [0002] The in vivo optical measurement device is a device that can easily measure the blood circulation, blood running state and hemoglobin changes in the living body, with low constraints on the measured body, and without causing damage to the living body. In general, in vivo optical measurement devices often report the measured cerebral cortex activation state that occurs between a quiet subject (regulatory subject) and a stimulating subject. [0003] For example, Non-Patent Document 1 reports a change in hemoglobin in the cerebral cortex between "repetition of meaningless utterance" (quiet item) and language-associative utterance (stimulant item). [0004] Also, Non-Patent Document 2 reports changes in hemoglobin in the cerebral cortex when a button is pressed and an inhibit...
