Now we can visualize the activity of neurons
Technology that can visualize nerve cells firing- short science news and articles

Researchers have developed a non-invasive technology to detect firing of nerve cells on the basis of changes in shape. When neurons fire, there is a change in the electrical potential of the cells, but also there are subtle variations in the shape of the neuron.

This leads to a very high signal to noise ratio and hence the researchers have developed an interferometric microscope with a high-speed camera which collects 50,000 frames per second. They further developed a new algorithm that can detect that part of the neuron which moves the most further boosting the signal.

This technology can be used to observe the neuronal activity in light-accessible parts of the body such as the eyes which could help us monitor visual functions at a cellular level.
