Embodiment

[0083] Such as Figure 11 As shown, the device was used to measure the change of the simple response of the mice after exposure to hypoxia - psychoneural reactivity, and the experiment was divided into hypoxia group (Hyp) and normoxia group (con)

[0084] After 21 days of exposure, the changes in the operating conditioning of the mice to the established stimulus light were measured again. Through repeated measurements for 3 days, it can be found that compared with the normal oxygen group, the response rate in the mental alertness of the mice in the hypoxic group was correct. (Correct%) did not change significantly, but the response time (response time) was significantly prolonged on the first day of the test, and the response time on the second and third day was not significantly different from the normoxia group, suggesting that hypoxia exposure may be transient Affects mental alertness in mice.

[0085] Such as Figure 16 As shown, using this device to measure, use the met...

Abstract

The invention discloses a detection device and detection method for detecting mental alertness of rodents. The detection device comprises an operation bin and a base, wherein the top wall, the front side wall and the rear side wall of the operation bin are connected with the left side wall and the right side wall of the operation bin through a fixing assembly; a metal net, a movable rod, a loudspeaker, an environment lamp, a stimulation lamp, a lifting rod and a feeding trough are arranged in the operation bin; the loudspeaker, the stimulation lamp, the lifting rod and the feeding trough are all arranged on the inner wall of the left side of the operation bin, the environment lamp is arranged on the inner wall of the rear side of the operation bin, the feeding trough is connected with a food dispenser through the conveying channel, the food dispenser is arranged on the mounting frame, the mounting frame is arranged on the base, the loudspeaker, the environment lamp, the stimulation lamp, the lifting rod and the food dispenser are all electrically connected with a control device, the control device is connected with the computer through a transmission line, the control device is arranged on the outer wall of the left side of the operation bin, and a collecting box is arranged below the metal net.

Description

technical field [0001] The invention belongs to the field of experimental equipment for psychology, and in particular relates to a detection device and a detection method for detecting the mental alertness of rodents. Background technique [0002] The mental alertness test (PVT) is a commonly used method for evaluating alertness, which mainly detects the subject's sustained attention and reaction time to stimuli. Central fatigue can be better assessed, and fatigue assessment for a variety of high cognitive load and environmental stimulation tasks (such as aerospace operations, etc.) is a routine and effective assessment method. [0003] At present, the detection methods of the mental state of rodents that are widely used mainly include forced swimming test, elevated cross test, etc., which observe the reaction of animals to extreme environments and test the mental state of animals. There is no specific detection method for the state of mental alertness under higher frequenc...
