Emotion in action: When emotions meet motor circuits

Area of Science:

• Neuroscience
• Behavioral Science
• Motor Control

Background:

• The brain integrates sensory, cognitive, and emotional data to guide motor behavior.
• Neural circuits are critical for regulating emotional and motor processes.
• Emotions significantly impact motor performance in both normal and pathological states.

Purpose of the Study:

• To investigate how emotional states shape movement by linking emotional processing circuits to motor circuits.
• To provide a comprehensive overview of emotion's impact on motor control in humans and rodents.
• To identify emotion-related brain structures that modulate motor output.

Main Methods:

• Review integrates findings from anatomical tracing, circuit-based dissection, and behavioral studies.
• Studies include both animal and human subjects.
• Utilizes techniques like electrophysiology, imaging, and optogenetics.

Main Results:

• Emotional processing circuits are extensively connected to the motor system.
• These circuits drive emotional behaviors and continuously shape ongoing movement.
• Identified emotion-related structures capable of modulating motor output behaviorally and anatomically.

Conclusions:

• The relationship between emotion and movement provides valuable insights into human behavior.
• Understanding this connection can enhance performance and improve mental and physical health.
• This review offers a comprehensive overview of the emotional modulation of movement in physiological and pathological conditions.
