Editing Magnetoencephalography (section)

=== Fetal ===
MEG has been used to study cognitive processes such as [[visual perception|vision]], [[Hearing (sense)|audition]], and [[language processing]] in fetuses and newborns.<ref>{{cite journal | vauthors = Sheridan CJ, Matuz T, Draganova R, Eswaran H, Preissl H | title = Fetal Magnetoencephalography - Achievements and Challenges in the Study of Prenatal and Early Postnatal Brain Responses: A Review | journal = Infant and Child Development | volume = 19 | issue = 1 | pages = 80–93 | year = 2010 | pmid = 20209112 | pmc = 2830651 | doi = 10.1002/icd.657 }}</ref> Only two bespoke MEG systems, designed specifically for fetal recordings, operate worldwide.<ref name="Frohlich_2023">{{cite journal | vauthors = Frohlich J, Bayne T, Crone JS, DallaVecchia A, Kirkeby-Hinrup A, Mediano PA, Moser J, Talar K, Gharabaghi A, Preissl H | title = Not with a "zap" but with a "beep": Measuring the origins of perinatal experience | journal = NeuroImage | volume = 273 | pages = 120057 | date = June 2023 | pmid = 37001834 | doi = 10.1016/j.neuroimage.2023.120057 | s2cid = 257807321 | doi-access = free | url = https://psyarxiv.com/65zsc/download }}</ref> The first was installed at the [[University of Arkansas at Little Rock|University of Arkansas]] in 2000, and the second was installed at the [[University of Tübingen]] in 2008. Both devices are referred to as [[Superconducting QUantum Interference Device|SQUID]] arrays for reproductive assessment (SARA) and utilize a concave sensor array whose shape compliments the abdomen of a pregnant woman. Fetal recordings of cortical activity are feasible with a SARA device from a gestational age of approximately 25 weeks onward until birth. Although built for fetal recordings, SARA systems can also record from infants placed in a cradle head-first toward the sensory array.<ref name="Frohlich_2023" /> A third high density custom-made unit with similar whole abdomen coverage has been installed in 2002 at the University of Kansas Medical Center to assess fetal electrophysiology.<ref>{{Cite web |date=2002-12-10 |title=CTF installs MEG system at KUMC |url=https://www.auntminnie.com/industry-news/article/15563780/ctf-installs-meg-system-at-kumc |access-date=2024-10-22 |website=AuntMinnie |language=en-us}}</ref><ref>{{cite journal | vauthors = Minai U, Gustafson K, Fiorentino R, Jongman A, Sereno J | title = Fetal rhythm-based language discrimination: a biomagnetometry study | journal = NeuroReport | volume = 28 | issue = 10 | pages = 561–564 | date = July 2017 | pmid = 28538518 | pmc = 5611858 | doi = 10.1097/WNR.0000000000000794 }}</ref> While only a small number of devices worldwide are capable of fetal MEG recordings as of 2023, the proliferation of [[Optically pumped atomic magnetometer|optically pumped magnetometers]] for MEG in neuroscience research<ref>{{cite journal | vauthors = Brookes MJ, Leggett J, Rea M, Hill RM, Holmes N, Boto E, Bowtell R | title = Magnetoencephalography with optically pumped magnetometers (OPM-MEG): the next generation of functional neuroimaging | journal = Trends in Neurosciences | volume = 45 | issue = 8 | pages = 621–634 | date = August 2022 | pmid = 35779970 | pmc = 10465236 | doi = 10.1016/j.tins.2022.05.008 | s2cid = 250122240 | doi-access = free }}</ref> will likely result in a greater number of research centers capable of recording and publishing fetal MEG data in the near future.<ref name="Frohlich_2023" />
