Narration

Before arguing, I will summarize some relevant background materials. First, I will explain how 'mirror neurons' had discovered and have studied. A mirror neuron is a neuron that fires both when the animal observes the same action performed by another. Thus, observer looking at other acting, it feel as though itself is acting. In humans, brain activity consistent with that of mirror neurons has been found in the premotor cortex, the supplementary motor area, the primary somatosensory cortex and the inferior parietal cortex.

Mirror neuron was found during neurophysiologists preforming experiment about monkey's action and its brain. During experiment monkeys were allowed to reach for pieces of food and single neuron in its brain was recorded. Researchers found that some of the neurons respond when the monkey see someone pick up the food as well as when monkey pick up the food. In other words, some neurons in monkey's brain responded when they see a person's action as the monkey itself acts. Later, researchers confirmed that about 10% of neurons in the monkey inferior frontal and inferior parietal cortex 'mirror' and respond similarly to performed hand action and observed.

However, there are some problem not yet solved about mirror neurons. There are neuroscientists who caution that the claims being made for the role of mirror neurons are not supported by adequate research. Also, it is not normaly possible to study single neuron in the human brain.

Second, here is the definition of autism. Autism spectrum disorder (ASD) and autism are both general terms for a group of complex disorders of brain development. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors.

Finally, the theory of mind means the cognitive ability that can imagine and understand other's perspective.
