| Outline of Final Research Achievements |
Towards novel measurement methods of neural activities based on tiny magnetic fields generated from them, we fabricated a high-sensitivity multi-channel optically pumped atomic magnetometer with a K-Rb hybrid cell. We demonstrate that high-density measurements of the magnetic field distributions with the interval of 4 mm could be achieved. Meanwhile, we developed a spin-lock MR sequence and were able to detect oscillatory magnetic fields directly with is as the change in MR signals. In addition, we showed the possibility of the direct measurement of functional connectivity based on MR signal contrasts depending on initial phases.
