Problems solved by technology

[0004] However, the inventors found that the existing fixation devices and fixation methods still have the disadvantages of being difficult to combine with magnetic resonance imaging and unable to ensure that the mouse's head movement is restricted when the mouse is awake.

Abstract

The invention aims to provide a mouse head fixing device for magnetic resonance imaging, which can limit the moving and rotating range of the head of a sober mouse after being fixed, and aims to provide a method for fixing the mouse head, which adopts the mouse head fixing device. The mouse head fixing device for realizing the above purpose comprises a pair of grasping arms and a connecting part,wherein the connecting part is connected with the pair of the grasping arms; the connecting part comprises a boss which is protruded upwards in an arc shape from two ends to the center; one or more sides of the boss extend outwards in an arc shape and protruding manner in the width direction of the fixing device to form an arc-shaped surface; and the arc-shaped surface is a fixing surface which isin contact with the head of the mouse.

Description

technical field [0001] The invention relates to a mouse head fixation device for magnetic resonance imaging and a fixation method thereof. Background technique [0002] In clinical scientific research (such as models of chronic brain lesions and models of acute trauma), mice are often selected as model animals for fMRI experiments. However, no matter whether it is a study of mice in a non-task state or a task state, anesthesia was often used in the past, mainly because the fMRI signal is easily affected by head movement, and the anesthesia method can control the head movement of mice at an ideal scale Inside. However, the state of anesthesia will inevitably change the activity level of the whole brain. On the one hand, the signal-to-noise ratio of the obtained image is low (the change of blood oxygen in the suppressed state is small), and on the other hand, the results from different researchers are difficult to compare (due to different anesthetic drugs and concentration...
