Scientists who continue their studies at the California Institute of Technology have signed a job that will go down in history. Using a special camera system, the experts were able to record the images of the signals sent from the nerve cells with these cameras. Let’s look at the details of this important scientific development together.
To achieve their goals, scientists developed a special camera using the ultra-fast photography technology called Diff-CUP. These cameras were fast enough to record 70 trillion frames per second. However, this camera alone was not enough. Experts combined the camera with a device called an interferometer and were able to colorize the signals passing through nerve cells with the most basic expression. The signals “illuminated” by laser beams sent with the interferometer were visualized with Diff-CUP.
Here is the image of the signals sent from the nerve cells
You may have a hard time understanding what we are talking about so far. Now we will tell you what the above image means. As you know, the control center of the body is the brain. Our nervous system transmits commands from the brain to our organs/limbs, and transmits external stimuli to our brain. When we touch something, we perceive whether it is soft or hard, as a result of our brain’s interpretation of the signals sent by our nerve cells. The image above shows exactly these signals.
The scientists imaged the signal passages of different nerve cells. This is exactly why the signals appear at different times above. So much so that the conduction velocity of the nerves ranges from 4 m/s to 120 m/s. This changes the time it takes for a nerve signal sent from the brain to reach the targeted point. By the way; By the time we mean here, we don’t mean minutes or seconds. A signal sent from a person’s brain can reach the tip of his feet in just milliseconds…
