Consistent with preclinical studies, adults with depression have been reported to have multiple alterations of the hypothalamic pituitary adrenal axis (9), increased cerebrospinal fluid corticotropin - releasing hormone (10), elevated cerebrospinal fluid norepinephrine concentration (11), decreased cortical γ - aminobutyric acid measured in vivo using proton magnetic resonance spectroscopy (12), and multiple indicators of altered serotonin (5 - HT) functioning (13), including reduced serotonin transporter (5 - HTT) availability as evidenced by reduced [123I] β - CIT spect binding (14).

In each case, binding leads to a characteristic proton nuclear magnetic resonance (1H NMR) for the dihydrogen that appears in a spectral window in the range delta = 0 to -20 parts per million, and as well to characteristic values of the coupling JHD and of the relaxation time T1.

In developing this idea, the team clarified the distribution of protons and oxygen vacancies in Sc - doped BaZrO3 by combining nuclear magnetic resonance spectroscopy and thermogravimetric analysis.

By using a nuclear magnetic resonance (NMR) technique, the distribution of proton and oxygen vacancy in Sc - doped BaZrO3 was clarified.

Traditional magnetic resonance imaging works in a similar way, tracking the magnetic response of protons to assemble a 3 - D image.

After ruling out all other possibilities, they figured out that the dip was from a phenomenon called cyclotron resonance scattering, which occurs when charged particles — either positively charged protons or negatively charged electrons — circle around in a magnetic field.

Cyclotron resonance scattering creates telltale signatures in a star's spectrum of light and the presence of these patterns, called cyclotron lines, can provide information about the strength of the star's magnetic field — but only if the cause of the lines, whether it be protons or electrons, is known.
