SQUID magnetometer and Josephson Junctions

Both Parkinson’s disease and epilepsy involve aberrations in brain wave activity which have eluded non-invasive monitoring until now.    German neuro-physicists report “MEG [magnetoencephalography] based on an ultralow-noise superconducting quantum interference device (SQUID) is shown to enable the first noninvasive single-trial characterization of human cortical population spikes, revealing amplitudes highly variable between trials and intertrial correlated response latencies. Thus, by expanding the scope of noninvasive neurotechnology, ultralow-noise MEG can support single-trial analyses of input–output characteristics in the human brain.”   MORE
