Modality-Specific Cognitive Function of Medial and Lateral Human Brodmann Area 6
TLDR
Direct physiological evidence of modality-specific cognitive function within human BA6 is provided and converging results demonstrate a functional double dissociation in which medial BA 6 has a critical role in updating verbal information and lateral BA6 has arole in updating spatial information.

Neural systems underlying observation of humanly impossible movements: an FMRI study.
TLDR
The results suggest that while premotor areas code human actions regardless of whether they are biologically possible or impossible, sensorimotor parietal regions may be important for coding the plausibility of actions.
Dynamic Parieto-premotor Network for Mental Image Transformation Revealed by Simultaneous EEG and fMRI Measurement
TLDR
Results suggest that motor signals from the premotor area were utilized for mental image transformation in the parietal areas and for updating the imagined clock hands represented in the right posterior parietal cortex.
Role of Broca's area in motor cognition
TLDR
The results converge to the view that Broca’s area is crucially involved in learning and processing structured sequences whatever their type: abstract or more ecological (action sequences), motor or cognitive, and thus emphasize its role as a possible “supramodal syntactic processor”.
“What” Becoming “Where”: Functional Magnetic Resonance Imaging Evidence for Pragmatic Relevance Driving Premotor Cortex
TLDR
Functional magnetic resonance imaging was used to investigate whether the learning of arbitrary stimulus-response mappings influences this functional dissociation between dorsal and ventral premotor cortex and the effects of the attended stimulus property, the motor effector assigned to it, and the spatial arrangement of the targets.
Class Dependency in Observers ’ Motor Areas Revealed by Functional Magnetic Resonance Imaging
TLDR
Observed intransitive motions to engage premotor areas along a gross-scaled somatotopy confirm that the human premotor cortex responds not only to the observation of goal-directed (transitive) motion but also to intransive motion.

Attention versus Intention in the Primate Premotor Cortex
TLDR
Data from neurophysiological experiments designed to dissociate neuronal activity related to visuo-spatial attention from preparatory activity in the monkey brain are reviewed, indicating strong similarities in the functional organization of dorsal premotor cortex of human and monkey.
Spatial attention and memory versus motor preparation: premotor cortex involvement as revealed by fMRI.
TLDR
fMRI results indicate that the brain networks underlying the two functional domains overlap in the caudate nucleus and presupplementary motor area, and possibly in lateral prefrontal cortex as well, but involve different dorsal premotor fields.
Dynamic patterns make the premotor cortex interested in objects: influence of stimulus and task revealed by fMRI.
Premotor cortex in observing erroneous action: an fMRI study.
The role of rostral Brodmann area 6 in mental-operation tasks: an integrative neuroimaging approach.
TLDR
The results of the present study suggest that the PMdr is important in the rule-based association of symbolic cues and responses in both motor and nonmotor behaviors.
Interval and ordinal properties of sequences are associated with distinct premotor areas.
TLDR
The findings suggest overlapping but different kinds of sequential representation, depending on both the ordinal and interval aspects as well as motor requirements, in the preSMA, SMA, MI and medial CE.
Selective Activation of a Parietofrontal Circuit during Implicitly Imagined Prehension
TLDR
The results show that in contrast to preparation of overt actions, preparation of either hand for covert movement simulation activates a large network of motor-related areas located primarily within the left cerebral and right cerebellar hemispheres, which concludes that motor imagery involves action-specific motor representations computed in parietofrontal circuits.
Action observation activates premotor and parietal areas in a somatotopic manner: an fMRI study
TLDR
Results bring the previous concept of an action observation/execution matching system (mirror system) into a broader perspective: this system is not restricted to the ventral premotor cortex, but involves several somatotopically organized motor circuits.
