Dorsal and ventral streams across sensory modalities

Area of Science:

• Neuroscience
• Cognitive Science
• Sensory Processing

Background:

• The Milner and Goodale model explains visual information use for human actions.
• This model's concepts have been extended to other sensory modalities like audition and touch.
• Current models of sensory processing often focus on modality-specific pathways.

Purpose of the Study:

• To review current models of dorsal and ventral streams across vision, audition, and touch.
• To propose a new approach for understanding brain function by decoupling action and perception from specific senses.
• To highlight the limitations of modality-specific models in explaining complex brain functions.

Main Methods:

• Literature review of existing dorsal and ventral stream models.
• Analysis of theories extending the Milner and Goodale model to non-visual senses.
• Conceptual synthesis of action and perception mechanisms across different sensory modalities.

Main Results:

• Dorsal and ventral stream concepts are increasingly applied beyond vision to audition and touch.
• The original Milner and Goodale model provides a foundational framework for cross-modal stream research.
• Existing models may not fully capture the interplay between action and perception independent of sensory input.

Conclusions:

• Advancing brain function knowledge requires models that explain action and perception independently of sensory modalities.
• A unified framework for action and perception, transcending individual senses, is crucial for future neuroscience research.
• Future research should focus on developing and testing modality-independent models of brain processing.
