Temporal Binding in Multisensory and Motor-Sensory Contexts: Toward a Unified Model.

Area of Science:

• Neuroscience
• Computational Neuroscience
• Sensory Integration

Background:

• The brain processes numerous sensory signals daily.
• Coherent perception and motor control require temporal binding of signals from common causes.
• Distinct mechanisms were historically proposed for multisensory and motor-sensory temporal binding.

Purpose of the Study:

• To review the literature on temporal binding in multisensory and motor-sensory contexts.
• To propose future research directions.
• To identify common computational principles underlying temporal binding.

Main Methods:

• Literature review of multisensory and motor-sensory temporal binding.
• Critical evaluation of recent research findings.
• Synthesis of evidence supporting common computational principles.

Main Results:

• Temporal binding mechanisms in multisensory and motor-sensory contexts may share common principles.
• These principles are rooted in Bayesian inference and uncertainty reduction.
• Unconscious causal inference, inspired by Helmholtz, provides a unifying framework.

Conclusions:

• A unified computational framework can explain temporal binding across sensory and motor domains.
• Future research should explore these shared Bayesian principles.
• Advancing the understanding of sensory integration and motor control.
