Summary
This study explores the neurophysiology of locomotion, focusing on the central pattern generator (CPG) and brainstem modulations in animal models. It details how spinal networks, sensory feedback, and brainstem pathways control movement, including skilled locomotion.
Area of Science:
- Neuroscience
- Locomotion
Context:
- Explores the neurophysiological basis of locomotion.
- Excludes biomechanical aspects, focusing on neural control mechanisms.
- Utilizes animal models (lamprey, cat) for experimental insights.
Purpose:
- To review the neurophysiological aspects of locomotion.
- To describe the spinal central pattern generator (CPG), its neurochemical constituents, and sensory feedback.
- To analyze supraspinal modulations, including brainstem, vestibular, and cerebellar influences on locomotor networks.
Summary:
- Investigates three levels of neural organization: spinal CPG, supraspinal modulations, and higher-level visuo-motor coordination.
- Highlights the role of neurochemical constituents and phased sensory feedback in spinal locomotor networks.
- Examines the involvement of brainstem, vestibular nuclei, red nucleus, cerebellum, and motor cortex in controlling locomotion.
Impact:
- Provides a comprehensive neurophysiological overview of locomotion control.
- Elucidates the intricate neural circuitry underlying coordinated movement.
- Suggests a framework for understanding visuo-motor coordination in skilled locomotion.
