Editing Interference theory (section)

===Brain structures===
Retroactive Interference has been localized to the left anterior ventral [[prefrontal cortex]] by [[magnetoencephalography]] (MEG) studies investigating Retroactive Interference and [[working memory]] in elderly adults.<ref name = Solesio>{{cite journal | last1 = Solesio | first1 = E. | last2 = Lorenzo-López | first2 = L. | last3 = Campo | first3 = P. | last4 = López-Frutos | first4 = J.M. | last5 = Ruiz-Vargas | first5 = J.M. | last6 = Maestú | first6 = F. | year = 2009 | title = Retroactive interference in normal aging: A magnetoencephalography study | journal = Neuroscience Letters | volume = 456 | issue = 2| pages = 85–88 | doi=10.1016/j.neulet.2009.03.087 | pmid=19429139| s2cid = 6152036 }}</ref> The study found that adults 55–67 years of age showed less magnetic activity in their prefrontal cortices than the control group. Executive control mechanisms are located in the [[frontal cortex]] and deficits in [[working memory]] show changes in the functioning of this brain area.<ref name="Solesio"/>
