Neural bases of action abstraction.

چکیده
There has been recent debate over whether actions are processed primarily by means of motor simulation or cognitive semantics. The current study investigated how abstract action concepts are processed in the brain, independent of the format in which they are presented. Eighteen healthy adult participants viewed different actions (e.g., diving, boxing) in the form of verbs and schematic action pictograms while functional magnetic resonance imaging (fMRI) was collected. We predicted that sensorimotor and semantic brain regions would show similar patterns of neural activity for different instances of the same action (e.g., diving pictogram and the word 'diving'). A representational similarity analysis revealed posterior temporal and sensorimotor regions where specific action concepts were encoded, independent of the format of presentation. These results reveal the neural instantiations of abstract action concepts, and demonstrate that both sensorimotor and semantic systems are involved in processing actions.

Abstraction plays an important role in digital design, analysis and verification. This paper introduces a word-level abstraction of the function implemented by a combinational logic circuit. The abstraction provides a canonical representation of the function as a polynomial Z =F (A) over the finite field F2k , where Z,A represent the k-bit word-level output and input of the circuit, respectivel...
متن کاملAction mirroring and action understanding in children
The past decade has experienced an increasing interest in action underestanding and children’s mirroring of others’ behavior. Behavioral investigations have focused on the development and significance of mimicry, goal prediction and imitation. Others have focused on the neural basis of action mirroring, identifying particular electrophysiological markers or related brain regions. A vivid debate...
متن کاملAbstraction, desalination and recharge method to control seawater intrusion into unconfined coastal aquifers
In this study, abstraction, desalination and recharge method and SEAWAT numerical model are used to investigate seawater intrusion repulsion in a hypothetical two-dimensional coastal aquifer to understand the relation of seawater intrusion with abstraction, desalination and recharge parameters (i.e. abstraction/recharge rate, wells distance and depth). Abstraction, desalination and recharge con...
متن کاملPlan Synthesis for Knowledge and Action Bases
We study plan synthesis for a variant of Knowledge and Action Bases (KABs), a rich, dynamic framework, where states are description logic (DL) knowledge bases (KBs) whose extensional part is manipulated by actions that possibly introduce new objects from an infinite domain. We show that plan existence over KABs is undecidable even under severe restrictions. We then focus on state-bounded KABs, ...
متن کاملHierarchical grouping of non-connected structures
We review multilevel hierarchies under the special aspect of their potential for abstraction and grouping. Motivated by claims to ’bridge the representational gap between image and model features’ and by the growing importance of topological properties we discuss several extensions to dual graph pyramids: structural simplification should preserve important topological properties and content abs...
