Mirror, Mirror on the Mind Essay

The sight of a strangers tail end getting hammered induces an instant surge of sympathy within us. watch a friend nauseate after eating something repulsive cursorily causes our own stomachs to turn. This ability to understand and relate to another individuals internal state has provided great motivation for research. One source of bill arose from research on reverberate neurons-which fire both during execution and musing of a behaviour (Rizzollati & Arbib, 1998). This particular class of neurons plays a life-or-death function in human neighborly interactions. The importance of the mirror neuron system (MNS) for colloquy can be understood through its find out on non communicative communication including facial expressions and contribute movements and verbal diction. Furthermore, carks bear upon human communication-such as autism and schizophrenia-convey the impression of stemming from a malfunctioning MNS.Generally, human sociable interaction involves both verbal an d nonverbal forms of communication. Obvious examples of nonverbal communication are facial expressions and hand gestures. A recent functional charismatic resonance imaging (fMRI) study by Montgomery and Haxby (2008) entrap secern supporting the claim that the MNS contains distinct representations for facial expressions and hand gestures. Particularly, this study examined the insufficient parietal lobule and the head-on operculum as the potential MNS brain regions involved in nonverbal communication. Further cause comes from another fMRI study by Montgomery, Isenberg and Haxby (2007)-which demonstrated the activation of the MNS during hand movements use to manipulate objects and hand gestures used to communicate.A third fMRI study by Van, Minderaa and Keysers (2007) highlighted similar results by examining other putative MNS brain regions-inferior anterior gyrus, posterior parietal cortex, insula and amygdala-thought to be associated with facial expressions. Activity spontaneou sly increased in the MNS of participants that produced and observed definite facial expressions (Van et al., 2007). A study by Enticott, Johnston, Herring, Hoy, and Fitzgerald (2008) demonstrated an associations between mirror neurons and facial emotion processing. Instead of using fMRI as a method of analysis, Enticott and colleagues (2008) used the transcranial magnetic stimulation (TMS) technique. In brief, much evidence supporting the involvement of the MNS in the processes of facial expression and hand gesture exists. Such forms of communication form the basis for the later, more complex, verbal expression evolution.Taking this thought gain ground, verbal language also seems to be connect to the MNS. Firstly, Rizzollati et al. (1998) marked the discovery of mirror neurons in the F5 area within the monkeys frontal cortex. This primate-specific F5 area has been considered to be the homolog of the human Brocas area, which is a region decisive for language (Rizzollati et al., 1998). With this in mind, Horwitz et al. (2003) demonstrated that both spoken and signed language are associated with mirror neurons firing in Brocas area as a result of the production of language. In addition, an fMRI study by Aziz-Zadeh, Wilson, Rizzollati, and Lacoboni (2006) made evident that the MNS of the premotor cortex is activated both when participants observed mouth, hand and foot movements and when participants read phrases related to these body parts. Overall, these findings suggest that indeed the MNS influences verbal language.Moreover, another way of understanding the importance of the mirror neurons influence on human social interaction is by considering the consequences of a malfunctioning system. Autism spectrum malady is characterized by social and language impairments. In other words, individuals with autism tend to be less interactive when it comes to communicating with others. Part of the MNS-the posterior inferior frontal and rostral inferior parietal areas are affiliated with social behaviour and apelike learning however these areas have deficits in autistic individuals (Locoboni & Mazziotta, 2007). In one study individuals with autism spectrum disorder showed significantly different electroencephalography (EEG) recordings of mirror neurons compared to a control group consisting of healthy individuals (Oberman, Hubbard, McCleery, Altschular, Ramachandran, & Pineda, 2005).Similarly, schizophrenia is another disorder characterized by deficits in social communication, especially of the nonverbal type. Research by Kato Y., Muramatsu, Kato M., Shibukawa, Shintani, and Mimura (2011) using magnetoencephalography recordings on the right inferior parietal cortex showed uncharacteristic mirror neuron occupation in non-treated schizophrenia patients. Likewise, similar results were found in a study that tested mirror neuron activity using TMS, it was demonstrated that during action observation a reduction in motor facilitation occurs in schizophrenia patients (Enticott, Hoy, Herring, Johnston, Daskalakis, & Fitgerald, 2008). Clearly, communication impairments observed in individuals with autism and schizophrenia are influenced by the MNS.In conclusion, human social interaction is influenced by mirror neurons. Evidence supports this statement through research do on the involvement of the MNS in nonverbal communication, including facial expressions and hand gestures and verbal language. Research has also suggested that an impaired MNS negatively affects social interaction, which is exemplified in the cases of autism and schizophrenia. taken as a whole, combining mirror neurons role in mimetic behaviour and social interaction-the process through which humans possibly undertake new social knowledge becomes evident. Additionally, the presence of mirror neurons in order Primates as well as humans provide evidence for the development of social interaction over the course of evolution. Thus, in order to further stre ngthen their existing relationship, future research should examine the co-evolution of mirror neurons and social interaction.
