Human Cortex: Reflections of Mirror Neurons
نویسنده
چکیده
Claims to have identified mirror neurons in human cortex have been controversial. A recent study has applied an fMRI adaptation protocol to the problem and come up with novel evidence for the existence of movement-selective mirror neurons in human cortex.

Recent studies have reported the discovery of a group of neurons in the motor cortex of the brain's gray. These neurons are called mirror neurons. Rizzolatti and colleagues in 1990s discovered the first mirror neuron system in monkeys in the University of Parma. Mirror neurons in brain are responsible for understanding the actions and intentions of others. The mirror neuron system has an import...
متن کاملMirror Neurons and Their Reflections
Human mirror neuron system is believed to provide the basic mechanism for social cognition. Mirror neurons were first discovered in 1990s in the premotor area (F5) of macaque monkeys. Besides the premotor area, mirror neuron systems, having different functions depending on their locations, are found in various cortical areas. In addition, the importance of cingulate cortex in mother-infant rela...
متن کاملReflections of other minds: how primate social cognition can inform the function of mirror neurons.
Mirror neurons, located in the premotor cortex of macaque monkeys, are activated both by the performance and the passive observation of particular goal-directed actions. Although this property would seem to make them the ideal neural substrate for imitation, the puzzling fact is that monkeys simply do not imitate. Indeed, imitation appears to be a uniquely human ability. We are thus left with a...
متن کاملReflections on agranular architecture: predictive coding in the motor cortex
The agranular architecture of motor cortex lacks a functional interpretation. Here, we consider a 'predictive coding' account of this unique feature based on asymmetries in hierarchical cortical connections. In sensory cortex, layer 4 (the granular layer) is the target of ascending pathways. We theorise that the operation of predictive coding in the motor system (a process termed 'active infere...
متن کاملReflections on mirror neurons and speech perception.
The discovery of mirror neurons, a class of neurons that respond when a monkey performs an action and also when the monkey observes others producing the same action, has promoted a renaissance for the Motor Theory (MT) of speech perception. This is because mirror neurons seem to accomplish the same kind of one to one mapping between perception and action that MT theorizes to be the basis of hum...
