Summary

Luca Bonini, from the University of Parma, delivers a keynote at the CAOS 2024 workshop on concepts, actions, and objects. He begins by acknowledging the 15th edition of the workshop and outlines practical announcements. His talk critically examines the classical distinction between canonical neurons and mirror neurons in the primate motor system. He reviews historical evidence from the 1990s, including the discovery of canonical neurons responding to objects and mirror neurons responding to observed actions. Bonini argues that the original definition of mirror neurons, requiring congruence between visual and motor responses, is not supported by recent data. He presents studies showing that many neurons in area F5 respond to objects alone and lack grip-type or goal congruence. He introduces the concept of ‘pragmatic remapping’, where object representations are modulated by the potential for action, as demonstrated by experiments with transparent barriers. He shows that a large proportion of neurons in AIP and F5 encode objects pragmatically, only when they are reachable and actionable. He also discusses agent selectivity and the role of space in shaping neuronal responses. The talk concludes by emphasizing the complexity and mixed selectivity of neurons, challenging simplistic categorizations.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides a high-value critical synthesis of decades of research on canonical and mirror neurons. Bonini systematically deconstructs the original criteria for mirror neurons, using recent empirical evidence to show that these criteria are not met. He argues for a more nuanced view where neurons exhibit mixed selectivity and pragmatic remapping. The argumentation is solid, grounded in specific studies and his own experimental data. He effectively uses examples and data visualizations to support his claims. The talk is persuasive and thought-provoking, offering a novel perspective on the function of the motor system.

Contribution & Novelties

The talk offers a critical reassessment of canonical and mirror neuron concepts, proposing the idea of ‘pragmatic remapping’ as a more accurate description of how the motor system processes objects and actions. It emphasizes the importance of mixed selectivity and the role of space in shaping neural responses. This challenges traditional views and suggests a more dynamic and context-dependent organization.
