The inferior frontal gyrus (IFG) is active during both goal-directed action and while observing the same motor act, leading to the idea that also the meaning of a motor act (action understanding) is represented in this "mirror neuron system" (MNS). However, in the dual-loop model, based on dorsal and ventral visual streams, the MNS is thought to be a function of the dorsal steam, projecting to pars opercularis (BA44) of IFG, while recent studies suggest that conceptual meaning and semantic…

Cortical Activation during Action Observation, Action Execution, and Interpersonal Synchrony in Adults: A functional Near-Infrared Spectroscopy (fNIRS) Study
The similarities in cortical activation between action execution and IPS suggest that neural control of IPS is more similar to its execution than observational aspects, suggesting that IPS is a higher-order process involving more bilateral activation compared to its sub-components.
A transcallosal fibre system between homotopic inferior frontal regions supports complex linguistic processing
The findings suggest that the right inferior frontal cortex not only processes paralinguistic aspects of language (such as affective prosody), as purported by the canonical model, but also supports the computation of linguistic aspects of varying complexity in the human brain.
Probing the role of the right inferior frontal gyrus during Pain‐Related empathy processing: Evidence from fMRI and TMS
Evidence is provided that the rIFG is involved in pain‐related empathy processing, which yields insights into how the brain perceives pain in others.
Boosting the Motor Outcome of the Untrained Hand by Action Observation: Mirror Visual Feedback, Video Therapy, or Both Combined—What Is More Effective?
It is found that MVF was the most effective approach to increase the performance of the target effector and the combination of MVF and VT turns out to be less effective looking from clinical perspective.
Differential Roles of Ventral and Dorsal Streams for Conceptual and Production-Related Components of Tool Use in Acute Stroke Patients.
The results suggest that in the use of tools, conceptual and production-related aspects can be differentiated and are implemented in anatomically distinct streams.


The Observation and Execution of Actions Share Motor and Somatosensory Voxels in all Tested Subjects: Single-Subject Analyses of Unsmoothed fMRI Data
A model is proposed that extends the original idea of the MNS to include forward and inverse internal models and motor and sensory simulation, distinguishing the M NS from a more general concept of sVx.
Functional segregation within pars opercularis of the inferior frontal gyrus: evidence from fMRI studies of imitation and action observation.
Data from seven functional magnetic resonance imaging studies involving observation and imitation of simple finger movements performed in the laboratory suggests a functional parcellation of the IFG that is discussed in terms of human mirror areas and the computational motor control architecture of internal models.

Ventral and dorsal pathways for language
The function of the dorsal route, traditionally considered to be the major language pathway, is mainly restricted to sensory-motor mapping ofsound to articulation, whereas linguistic processing of sound to meaning requires temporofrontal interaction transmitted via the ventral route.
Action Observation Circuits in the Macaque Monkey Cortex
The correlation of fMRI data with connectional data showed that visual action information, encoded in the STS, is forwarded to ventral premotor cortex (F5) along two distinct functional routes that emphasizes the object of the action and may aid in understanding motor acts with respect to their immediate goal.

Two action systems in the human brain
Ventral and dorsal fiber systems for imagined and executed movement
A dichotomy of fiber pathways into dorsal and ventral systems was found: the superior longitudinal fascicle was found to connect frontal and parietal regions involved in both overt and imagined movements, whereas a ventral tract via the extreme/external capsule (EmC/EC) connects cortical regions specific for motor imagery that were situated more anteriorly and posteriorly.

Functional magnetic resonance imaging revealed that premotor mirror neuron areas—areas active during the execution and the observation of an action—previously thought to be involved only in action recognition are actually also involved in understanding the intentions of others.
