The quantum optics group of INRiM, in collaboration with the departments of Drug Science and Technology and Physics of University of Torino, Italian

National Institute of Nuclear Physics and the Institute of Organic Chemistry and biochemistry of the Science Academy of Czech Republic, has been able to observe the temperature raise in a neuron induced by the increase of its "firing" activity for the first time, exploiting a quantum sensor based on the spin properties of Nitrogen-Vacancy centers in nanodiamonds. 

The results of the researchNanodiamond–quantum sensors reveal temperature variation associated to hippocampal neurons firing”, has been published in Advanced Science Journal on 25 July 2022. 

This result opens up various new possibilities for measurement and could lead to significant developments in the field of neuroscience.
