Racial differences in sympathetic nervous system indicators: Implications and challenges for research

Area of Science:

• Psychophysiology
• Neuroscience
• Racial Health Disparities

Background:

• Growing evidence suggests racial variations in sympathetic nervous system (SNS) functioning.
• The precise nature and consistency of these differences across various SNS activity indices are not well understood.
• Racial disparities in commonly used SNS activity measures require further investigation.

Conclusions:

• Racial differences in sympathetic nervous system (SNS) functioning exist, particularly evident in electrodermal activity (EDA).
• Further research is needed to clarify racial variations in other SNS indices like PEP and sAA.
• Addressing definitional, analytical, and interpretive issues is crucial for understanding group differences in psychophysiological activity.
