I am lucky enough to have access to a cuttingedge microscope with which I can take a picture of a mouse's brain.As neuroscience advances, we are aware that a lot of slight differences are lost if we can't see what's happening in each individual cell.With a series of experiments, we hope to image the same cells in the brain across several days, allowing us to follow each one's activity over time.
To image the mouse, we attach a plastic bar to the front of its head and then secure the b
ar to a headmounting device on the stage under the microscope lens.We did our first round of experiments, and though we thought we were imaging the same cells each time, the analysis indicated that was not the case.Using this technique was new in our lab, and while there are scientific papers with instructions, some of the little details were lost in translation.
Despite of this, when the next round of animals was ready, we came up with a solution fast to track the tilt (倾斜) of the mouse's head.We needed a way to indicate what position the mouse's head was in.We needed something easy and fast to track the position.Then the idea struck: a toothpick would be perfect.
We created two mini protractors (量角器): one for updown and one for leftright.And we broke the toothpick in half and stuck the rough edge to the headmounting device.The pointy end would point to a position on our scale, one for updown and one for leftright.And just with a toothpick and a bit of superglue, our problem was solved.
In any biology lab, you may see an object as common as a toothpick next to or even attac
hed to a very expensive piece of equipment.Keep in mind, next time you need a quick fix, there is probably something as common as a toothpick that can turn failure into success.
4．Why does the author conduct the experiments?
A.To observe the structure of a mouse's brain.
B.To research how images affect the human brain.
C.To study the function of a mouse's each brain cell.
D.To learn how a mouse brain is different from a human's.
5．What was a reason for the failure of the first round of experiments?
A.They had difficulty in using the microscope.
B.They lacked scientific instructions for reference.
C.They didn't understand the technique thoroughly.
D.They couldn't correctly distinguish the types of cells.
6．In the next round of experiments, a toothpick was used ________．
