At present, one of the most promising windows to the functional organization of the human
brain is magnetoencephalography (MEG). By mapping the magnetic field distribution outside …

… For example, it has long been proposed from EEG studies that an ERP occurring at around
100 ms after making an error (called the error-related negativity (ERN)) has an active source …

… Note that ERPs are already widely used in the diagnosis of certain neurological disorders
(eg, multiple sclerosis) and sensory disorders (eg, screening of neonates for hearing …

… The mean reaction times for correct trials were 668 ms ± 50 ms for HSF images, 723 ms ±
88 ms for LSF images, and 607 ms ± 52 ms for the intact images (t tests: LSF vs. HSF, t 8 = 2.34…

… The first major deflection occurs at about 70 ms after the stimulus. At present, we do not …
The different stimuli were then shown for a period of about 250 ms in random order, so that the …

… This analysis demonstrates a strong stimulus-induced power increase at about 20 Hz
and starting about 500 ms after the stimulus. Such rebounds of the oscillatory activity in the …

… MNE, and MCE of MEG recordings at 98 ms after the onset of the stimulus. The blue spot …
Figure 11 shows MNE and MCE of the somatosensory MEG experiment at 50 ms after the …

A 122-channel dc SQUID magnetometer with a helmet-shaped detector array covering the
subject's head has been operational in the Low Temperature Laboratory of the Helsinki …

… 60-ms wide-band noise bursts (2 kHz central frequency with 4 kHz bandwidth, 70 ms duration)
… In the somatosensory study, the right median nerve was stimulated at the wrist with 0.2 ms …

… a variance of 20 ms for the proximal drive and 15 ms for the distal drive and a 0-ms mean
delay … was simulated to last one beta period (∼50 ms). The distal drive set the PK3 duration, …
