Research Abstract |
In this study, a new method to detect weak magnetic fields arising from neuronal electrical activities using magnetic-resonance imaging (MRI) was developed to investigate the dynamics of brain function. Using this technique, it was possible to image neuronal activities in the rat brain by MRI. An imaging technique, which combines the transcranial magnetic stimulation and EEG measurement simultaneously, enabled us to estimate brain function with high spatial and temporal resolutions. The interaction of radio-frequency (RF) magnetic fields with iron cage proteins and the alteration of their functioning were investigated to observe the accumulation of amyloid by MRI.
