Essay / Mirror Neurons and Giacomo Rizzolatti - 1637
Mirror neurons are neurons that respond to goal-directed actions performed by oneself or others (Ward, 2010). Mirror neurons are so named because there are structures in the brain that become active when a person performs an act or when observing the act performed by another (Goolkasian, 2009). Giacomo Rizzolatti and his colleagues were the first to observe the mirror. neurons. In the early 1990s, they studied neurons in a monkey's premotor cortex that fired when the monkey picked up different objects. When one of the investigators picked up a piece of food while the monkey was watching, 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 proving information about the mirror neuron system. Evidence for this is provided by 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 when observing actions performed by others and therefore mirror-type activity. Other techniques, such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), rely on recording variations in blood flow in various brain regions during execution and movement. observation of given motor acts, and made it possible to localize a system of mirror neurons. for action (Rizzolatti and Craighero, 2004; Sinigaglia and Sparaci, 2010).
