Do sensorimotor perturbations to standing balance elicit an error-related negativity?

Area of Science:

• Neuroscience
• Cognitive Science
• Motor Control

Background:

• Error detection and correction are vital for adaptive behavior.
• Scalp electroencephalography (EEG) studies reveal frontocentral negativities like the error-related negativity (ERN) and balance N1 following errors in cognitive and postural tasks, respectively.
• These neural signals exhibit striking similarities despite originating from distinct research fields.

Purpose of the Study:

• To integrate literature from cognitive neuroscience and sensorimotor neurophysiology.
• To propose shared underlying neural mechanisms for the ERN and balance N1.
• To highlight the benefits of cross-disciplinary collaboration for understanding error processing.

Main Methods:

• Review of existing literature on the error-related negativity (ERN) in cognitive tasks.
• Review of literature on the balance N1 in postural control research.
• Comparative analysis of factors modulating both ERN and balance N1.

Main Results:

• The balance N1, elicited by precisely controlled postural errors, is significantly larger than the ERN.
• Factors such as motivation, perceived consequences, and aging modulate both ERN and balance N1.
• A strong case is made for the ERN and balance N1 reflecting common neural activity for error detection.

Conclusions:

• The ERN and balance N1 likely represent common neural processes for detecting errors.
• Investigating these signals across cognitive and motor domains can enhance understanding of error monitoring.
• Interdisciplinary research can elucidate the functional significance of error-related potentials and their role in motor and cognitive impairments.
