The Relationship between Saccades and Locomotion.

Area of Science:

• Neuroscience
• Biomechanics
• Ophthalmology

Background:

• Human locomotion relies on complex brain networks and visual feedback.
• Eye movements, including fixations and saccades, are crucial for navigation and environmental interaction.

Purpose of the Study:

• To review and synthesize current knowledge on the relationship between eye movements (fixations, saccades) and gait during locomotion.
• To explore the neural underpinnings and clinical implications of the interplay between eye movements and locomotion.

Main Methods:

• Literature review and synthesis of existing studies on eye movements during locomotion.
• Analysis of behavioral studies examining saccadic and gait impairments.

Main Results:

• Significant overlap exists between neural circuitry for locomotion and saccades.
• Animal studies suggest integration nodes between these overlapping circuits.
• Impairments in saccades and gait are observed in various disease states.

Conclusions:

• Eye movements and locomotion share common neural pathways.
• Further research into this shared circuitry holds potential for diagnostic and therapeutic advancements in neurological and visual disorders.
