Directional discrimination in the nociceptive system is enhanced for non-continuous lines

Key Points

• The aim is to explore how directional discrimination differs between non-continuous and continuous lines in the nociceptive system.
• Utilized a computational model to analyze directional discrimination.
• Compared responses to non-continuous and continuous stimuli in the nociceptive system.
• Measured receptor temperature to assess activation levels.
• Directional discrimination was better for non-continuous lines than for continuous lines.
• Continuous stimuli caused higher receptor temperature, suggesting increased activation.
• Higher spatial contrast in discrete stimuli likely enhances perceived stimulation intensity.
