The mirror-neuron system allows understanding actions by activating internal motor representations, regardless of sensory input. This system, crucial for action interpretation and speech, can develop through environmental interaction.

Area of Science:

Neuroscience
Cognitive Science
Motor Control

Background:

The mirror-neuron system is a cortical network enabling action understanding via internal representations.
This capability is not limited by visual stimulation amount or sensory modality (visual, auditory).

Purpose of the Study:

To explore the mirror-neuron system's role in action interpretation.
To present a model of the mirror-neuron system and test its implementation.
To investigate the development of mirror-like representations.

Main Methods:

Review of evidence on mirror-neuron system function.
Development and partial implementation of a computational model.
Experimental validation of the model's predictions.

Main Results:

Motor information significantly influences action interpretation.
Sensory cues evoking an action's 'idea' activate motor representations.
Mirror-like representations can form autonomously through individual-environment interaction.

Conclusions:

The mirror-neuron system is fundamental for understanding actions across sensory modalities.
Motor representations play a key role in interpreting observed actions.
Environmental interaction is sufficient for developing mirror-like representations.
