Embodiment 1:
At first need according to experiment, abnormal smells from the patient is conducted the olfactory sensation tester be connected with NMR, (this abnormal smells from the patient conduction olfactory sensation tester can be according to experimenter's needs on instrument, to set the program of testing then; 1-6 kind odor source is carried out the combination of 1-24 kind mode, and can the experimenter be measured) according to needing repetition automatically; Open abnormal smells from the patient conduction olfactory sensation tester main power; Open air pump, adjustments of gas flow, preparing experiment.
The setting of each experimental arrangement is according to the different odor that experiment will be checked the influence of the different reflector spaces of brain to be set, and understands which zone of brain like hope and respectively the fragrance of Flos Rosae Rugosae, the acid of Bulbus Allii and the tart flavour of vinegar is reacted.
At first we give current experiment a name; It is the combination in any of 4 bit digital or letter; Create a file, we can also set the 1-10 group in this experiment then, respectively these several kinds of odor sources are carried out the experiment of different order mode of movement; After configuring group, beginning setting program (PARADIGM SETTING): process is following
(be placed in which odor source and can select arbitrarily) placed the aroma source of Flos Rosae Rugosae respectively in 1,2, No. 3 odor source; The flavor source of Bulbus Allii, the flavor source of vinegar are provided with the time (between second, the time of delivery of every kind of abnormal smells from the patient all is identical to scope at 1-99) that abnormal smells from the patient is carried; The sequence of batching products of every kind of abnormal smells from the patient; Can arrange 24 kinds of orders (for example 1,2,3, perhaps 3,2,1), every kind of abnormal smells from the patient is set respectively then carry and accomplish the back and next abnormal smells from the patient is carried the dead time between beginning;
Set the number of repetition (PARADIGM EXE) of experiment mastery routine, determine that this experiment needs to carry out above-mentioned mastery routine several times;
Set device is receiving the mastery routine that how long brings into operation after NMR signal sends, and promptly with respect to the time delay of NMR signal, scope is 1-99 second, and (PARADIGM DELAY) prepares to make things convenient for the experimenter;
According to experimenter's respiratory frequency, the trunon delay time (TRIGGER DELAY) that carry in the setting smell source, time range is 0.1-9.9 second, so that experimenter's abnormal smells from the patient in air-breathing just in time delivers to, so as not to the invalid conveying that causes abnormal smells from the patient.
We can also detect the whether unimpeded of each odor source before formally beginning to test, and can detect through this function key of MANUAL, detect accomplish after, prove that each odor source is normal, get into next step.
After above program setting is good, i.e. experiment all set.
At first can under the situation of signal that breathes no more, once test (PARADIGM TRIGGER START), so that let the experimenter under naturalness, (not have TRIGGER DELAY); Accept the abnormal smells from the patient that mastery routine is sent at random; Understand experimenter's brain response,, after experiment is accomplished; Abnormal smells from the patient conduction olfactory sensation tester can be preserved the setting data of experiment and image and the data in the experiment automatically, consults for the experimenter.
Next; Can combine the experiment (RESP TRIGGER START) of breath signal; Before beginning experiment, the experimenter wants earlier the experimenter to be with respiration pickup, connects breath signal and carries out the identical situation inspection between breath signal and the abnormal smells from the patient transmission; Whether the time of the TRIGGER DELAY that set (PARADIGM CHECK) early stage for confirmation is accurate; If abnormal smells from the patient can not begin to deliver to when air-breathing experimenter's nose place the experimenter, then should adjust the time of TRIGGER DELAY, till both coincide.After adjustment is accomplished; TRIGGER OUT button is adjusted to TRIGGER IN state; This state requires NMR to enabling signal of abnormal smells from the patient conduction olfactory sensation tester exactly, and experiment could formally begin, and just has been connected with the NMR signal; If there is not the signal of nuclear magnetic resonance, NMR, experiment will can not begin; NMR sends to test behind the signal and formally begins, and experiment will be carried out according to the content that mastery routine is set, and experiment finishes all data of back and can be saved in automatically in the SD card, and the experimenter can consult.
