Evidence for a distributed hierarchy of action representation in the brain
Open accessAbstract
Complex human behavior is organized around temporally distal outcomes. Behavioral studies based on tasks such as normal prehension, multi-step object use and imitation establish the existence of relative hierarchies of motor control. The retrieval errors in apraxia also support the notion of a hierarchical model for representing action in the brain. In this review, three functional brain imaging studies of action observation using the method of repetition suppression are used to identify a putative neural architecture that supports action understanding at the level of kinematics, object centered goals and ultimately, motor outcomes. These results, based on observation, may match a similar functional-anatomic hierarchy for action planning and execution. If this is true, then the findings support a functional-anatomic model that is distributed across a set of interconnected brain areas that are differentially recruited for different aspects of goal-oriented behavior, rather than a homogeneous mirror neuron system for organizing and understanding all behavior.

The motor plant is probably one of the most important aspects of the environment for predicting sensory input.
“Indeed, the motor plant is probably one of the most important aspects of the environment for predicting sensory input (see Grafton and Hamilton 2007).”
From Action and behavior: a free-energy formulation (2010) · cites this paper as Grafton and Hamilton 2007
Section 4, “Computational models” (page unavailable), says forward models predict the motor plant’s state and turn motor commands into expected sensory consequences. It does not characterize the motor plant as an aspect of the environment or rank it among the most important factors for predicting sensory input. (LLM, conf=0.83)

“…between a sensory event and a motor response severely limit the use of feedback control (Keele, Cohen, & Ivry, 1990), newer behavioral work reveals mechanisms based on the integration of motor commands into estimation of state that can largely mitigate these delays (Desmurget & Grafton, 2000).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
