“…Schubotz (2007) proposed that the PMC serves as a predictive system, not only for human-like actions, but also for abstract sequences such as music or sea-waves, which cannot be mirrored by any human movement. This predictive role has also been suggested for the processing of grammatical rule systems (Bahlmann et al, 2009).…”

Repeated experiences with an event create the expectation that subsequent events will expose an analog structure. These spontaneous expectations rely on an internal model of the event that results from learning. But what happens when events change? Do experience-based internal models get adapted instantaneously, or is model adaptation a function of the solidity of, i.e. familiarity with, the corresponding internal model? The present fMRI study investigated the effects of model solidity on model adaptation in an action observation paradigm. Subjects were made acquainted with a set of action movies that displayed an altered script when encountered again in the scanning session. We found model adaptation to result in an attenuation of the premotor-parietal network for action observation. Model solidity was found to modulate activation in the parahippocampal gyrus and the anterior cerebellar lobules, where increased solidity correlated with activity increase. Finally, the comparison between early and late stages of learning indicated an effect of model solidity on adaptation rate. This contrast revealed the involvement of a fronto-mesial network of Brodmann area 10 and the ACC in those states of learning that were signified by high model solidity, no matter if the memorized original or to the altered action model was the more solid component. Findings suggest that the revision of an internal model is dependent on its familiarity. Unwarranted adaptations, but also perseverations may thus be prevented.

“…Findings replicated the typical and robust activation BOLD response pattern, with rhythmic, object-based and spatial sequence tasks activating lateral premotor fields in a ventral-to-dorsal succession. The HAPEM framework (Schubotz, 2007) explains these findings by a repertoire of styles of transformations, primarily coded in PM, that can be exploited for both action and perception. Accordingly, the prediction of an event that is structured with regard to a property P engages the sub-area of the lateral premotor cortex that is best adapted to specify its motor output in terms of property P. For instance, a spatially defined event (e.g.…”

The lateral premotor cortex (PM) of the macaque monkey is an anatomically multifaceted area, which serves multiple sensorimotor and cognitive functions. While evidence for the functional organization of human premotor cortex accumulates, much less is known about the underlying anatomical properties of this brain region. We used diffusion tractography and functional Magnetic Resonance Imaging (fMRI) to investigate whether the precentral gyrus in humans can be segregated on the basis of anatomical connectivity and of functional activation in a set of cognitive and motor tasks. Tractographic data suggested a distinction between ventral and dorsal premotor cortex, and furthermore inferior and superior sub-parcellation of both. Functional MRI data corroborated these four areas, showing that anatomical parcellation predicts the distribution of functional activation and vice versa (preliminary evidence). These results may encourage the application of combining diffusion tractography and fMRI in vivo in order to shed light on the correspondence of brain function and anatomy.3
