Topic > Mirror Neurons and Giacomo Rizzolatti - 1637

Mirror Neurons are neurons that respond to targeted actions performed by themselves or others (Ward, 2010). Mirror neurons are so called because there are structures in the brain that are activated when a person performs an act or when that person observes the act performed by another (Goolkasian, 2009). Giacomo Rizzolatti and colleagues were the first to observe the mirror neurons act. In the early 1990s, they were studying neurons in a monkey's premotor cortex that fired when the monkey reached for a different object. When one of the investigators picked up a piece of food while the monkey watched, the monkey's neurons fired. This led to the discovery of mirror neurons (Goldstein, 2014). Mirror neurons were originally discovered in the ventral premotor cortex (area F5) of the monkey brain (Sinigaglia & Sparaci, 2010). Although the evidence for the existence of mirror neurons in humans is still vague, there is still a large amount of data demonstrating information about the mirror neuron system. Evidence for this comes from neurophysiological and brain-imaging experiments (Rizzolatti & Craighero, 2004). EEG, MEG and TMS are methods that have made it possible to detect the activation of motor neurons during the observation of actions performed by others and therefore a mirror-like activity. Other techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), are based on the recording of blood flow variations in various brain regions during the execution and observation of certain motor acts, and have allowed to localize a system of mirror neurons for action (Rizzolatti & Craighero, 2004; Sinigaglia & Sparaci, 2010). From neuroimaging studies there is growing evidence that the fundamental components of the human mirror neuron system...... half of the article ......., Verbeke, W., Dietvorst, R., van den Berg, W., Bagozzi, R., & De Zeeuw, C.
