Mirror neurons have been localized in several locations, including the inferior parietal lobule (IPL). Increase of EEG alpha3/alpha2 frequency ratio has been detected in mild cognitive impairment (MCI) subjects who will convert in Alzheimerââ¬â¢s disease (AD). Three MCI groups were obtained according to increasing tertile values of alpha3/alpha2 ratio. Difference of cortical thickness among the groups was estimated. High a3/2 group had wider cortical thinning than other groups, mapped on the IPL, Supramarginal and Precuneus bilaterally. High EEG alpha3/alpha2 frequency power ratio was associated with atrophy of IPL areas in MCI subjects. A link between AD and disrupture of mirror neurons system could be hypothesized.
Scholarly peer review is the process of subjecting an author'sscholarlywork, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
