They found that viewing a hated person increased the activity in several brain regions, including the medial frontal gyrus, right putamen, premotor cortex, frontal pole, and medial insula bilaterally.
[30,31] Neural activation of primary motor cortex and recruitment of the premotor cortex toward the affected hemisphere, which helps in motor improvements by mirror therapy.
The mirror system is primarily comprised of the ventral premotor cortex (PMv, 1) and the inferior parietal lobule (IPL, 2).
These included areas mapped to gray matter in the right prefrontal cortex and the right premotor cortex and to white matter in both hemispheres of the cerebellum.
(29) They reported that before alcohol use, binge drinking adolescents had lower gray-matter volume in the superior frontal gyri (SFG) and greater volume in the premotor cortex compared to nondrinking control subjects.
Indeed, the activation of the primary motor and premotor cortex while processing words or sentences that describe action including movement of the mouth, hand or leg supports this theory (4).
exploited a new approach based on combined rTMS/high-density electroencephalography (hd-EEG) providing a direct noninvasive evidence for LTP bilaterally over the premotor cortex in humans induced by rTMS [34].
Compared with the control group, the elite group had increased GM volume in right (R) inferior temporal sulcus, premotor cortex (R), temporal pole superior (R), cerebellum, and lateral occipital sulcus.
Mirror neurons are a particular class of visuomotor neurons, originally discovered in area F5 of the monkey premotor cortex, that discharge both when a monkey does a particular action and when it observes another monkey or a human doing a similar action [24].
In the early nineties of the last century, the Italian scientist Giuseppe Di Pellegrino and his colleagues made an interesting discovery: neurons of area F5 of the premotor cortex of the monkey discharge while it is performing goal-directed hand movements, such as grasping, holding, and tearing, and many of these neurons are also active when the monkey observes specific, meaningful hand movements performed by the experimenters (176).
In contrast, patterns of empathic distress overlapped with systems in the brain known for mirroring, such as the premotor cortex and the primary and secondary somatosensory cortices, which help an individual simulate or imagine what another person is feeling or thinking.
