‘Human see, human do’ cortex

Spatiotemporal symmetry and multifractal structure of head movements during dyadic conversation.

“…Evidence has been reported in support of neural mechanisms (Iacoboni et al, 1999; Rizzolatti & Arbib, 1998; Rizzolatti & Craighero, 2004; Salenius, 1999) that may account for mirroring during conversation. Single-cell recordings of these mirror neurons from macaque monkeys (Gallese, Fadiga, Fogassi, & Rizzolatti, 1996) have demonstrated that neurons in premotor cortex area F5 show high activity both when an action is performed (such as grasping a grape and bringing it to the mouth) and when a similar action is observed to be performed by another primate.…”

“…These two functions are so deeply related that our comprehension of observed situations, which we therefore perceive through our visual system, could be 'decoded' only via our motor system. It has been demonstrated in particular that when we observe another person performing a certain movement, the complex cerebral activity induced by this observation includes activation of part of the same cortical area as activated by our own motor act (Salenius 1999). Of primary importance is the coupling between the visual and sensorimotor systems: in fact visual feedback is the basis of precise motor act control.…”
