Journal ArticleDOI
Sound frequency change detection in fetuses and newborns, a magnetoencephalographic study
Rossitza Draganova,Hari Eswaran,Pamela Murphy,Minna Huotilainen,Curtis L. Lowery,Hubert Preissl,Hubert Preissl +6 more
TL;DR: The mismatch negativity response to auditory stimuli has been successfully recorded in newborns thus demonstrating the discriminative cognitive ability and the aim of this study was to determine whether and when such an MMN response could be detected in the human fetus.
Journal ArticleDOI
Serial magnetoencephalographic study of fetal and newborn auditory discriminative evoked responses
Rossitza Draganova,Rossitza Draganova,Hari Eswaran,Pamela Murphy,Curtis L. Lowery,Hubert Preissl,Hubert Preissl +6 more
TL;DR: In the 28-39 week gestational age group, the discriminative brain responses to tone frequency change could be detected as early as 28 weeks, and although not statistically significant, a decrease in latency was observed with increase in Gestational age.
Journal ArticleDOI
Development of auditory evoked fields in human fetuses and newborns: A longitudinal MEG study
Manuela Holst,Hari Eswaran,Curtis L. Lowery,Pamela Murphy,Jonathan D. Norton,Hubert Preissl,Hubert Preissl +6 more
TL;DR: Findings indicate that MEG is a technique that can be used to investigate maturation of the auditory cortex based on auditory evoked fields in fetuses and neonates and is possible to trace the development of auditory responses in utero and newborns.
Journal ArticleDOI
Human fetal brain imaging by magnetoencephalography: verification of fetal brain signals by comparison with fetal brain models.
Jiri Vrba,Stephen E. Robinson,Jack McCubbin,Pamela Murphy,Hari Eswaran,James D. Wilson,Hubert Preissl,Hubert Preissl,Curtis L. Lowery +8 more
TL;DR: This work has concluded that the model of the electrically isolated fetal head is more appropriate for fMEG analysis and shows with the help of this model that the redistribution due to projection was properly corrected, and also, that the measuredfMEG is consistent with the known position of the fetal head.
Journal ArticleDOI
Habituation of visual evoked responses in neonates and fetuses: a MEG study.
Tamara Matuz,Rathinaswamy B. Govindan,Hubert Preissl,Hubert Preissl,Eric R. Siegel,Jana Muenssinger,Pamela Murphy,Maureen Ware,Curtis L. Lowery,Hari Eswaran +9 more
TL;DR: A habituation paradigm that allows the investigation of response decrement and response recovery and its applicability for measuring the habituation of the visually evoked responses (VERs) in neonatal and fetal magnetoencephalographic recordings is developed.
