Improved neuromagnetic detection of fetal and neonatal auditory evoked responses
OBJECTIVE To assess the quality of fetal and neonatal auditory evoked responses (fAERs and nAERs) obtainable with a low-noise, high-channel count SQUID gradiometer in a well-shielded environment. Expand

Development of MEG sleep patterns and magnetic auditory evoked responses during early infancy
OBJECTIVE To follow the development of MEG sleep patterns and auditory evoked responses (AERs) during the first six months of life. METHODS The subjects were 18 neonates, born at conceptional ageExpand

Noninvasive in utero assessment of PR and QRS intervals from the fetal magnetocardiogram.
Fetal cardiac waveform intervals were assessed from fetal magnetocardiogram (FMCG) recordings taken from 59 pregnant women at 17-41 weeks gestation. Beyond 27 weeks' gestation PR and QRS intervals,Expand

Fetal auditory evoked responses detected by magnetoencephalography.
Magnetoencephalography was used to noninvasively record auditory evoked responses from fetuses in utero at 34 to 37 weeks' gestation. The recordings were similar to auditory evoked responses fromExpand

Spectral analysis of antepartum fetal heart rate variability from fetal magnetocardiogram recordings.
Fetal heart rate variability was derived from fetal magnetocardiogram recordings in ten subjects at gestation ages 32-38 weeks. Maternal interference was negligible and R-wave detection was highlyExpand

On and Off magnetic auditory evoked responses in early infancy: A possible marker of brain immaturity
OBJECTIVE To follow the development of the auditory evoked on- and off-responses in early infancy. METHODS The subjects were healthy infants, studied at conceptional age (CA) 39-66 weeks. SerialExpand

Slow rhythms and sleep spindles in early infancy
OBJECTIVE To investigate the slow rhythm and its relationship to spindling in early infancy. METHODS We analyzed sleep MEG recordings containing sleep spindles, taken from 7 normal, healthyExpand

Importance of Fetal Arrhythmias to the Neonatologist and Pediatrician.
Sudden, unexplained death during the perinatal period remains a major, longstanding challenge. Recent advances in diagnostic techniques and genetic testing has provided evidence that a significantExpand

Spatiotemporal properties of the fetal magnetocardiogram.
OBJECTIVE Our purpose was to investigate the spatiotemporal properties of the fetal magnetocardiogram. STUDY DESIGN Fetal magnetocardiogram maps were measured for the first time in 20 subjects fromExpand
