|Mirror neurons were first reported in the premotor cortex of macaque monkeys. These neurons fire, both when a monkey performs a specific action, but also when the monkey simply watches another monkey carries out the same action. This was the first description of a neural mechanism that allowed a direct matching between the visual description of an action and its execution. There is now evidence, from functional imaging studies, to suggest that mirror neurons not only exist in man but are present in several locations, including the inferior parietal lobule (IPL). The inferior parietal lobule (IPL), even more so than the rest of the cortex, underwent an accelerated enlargement in the phylogenetic line leading to the great apes and hominids- splitting into the supramarginal and angular.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
