- * Pain and pleasure interoceptors are specialized intrinsic interoceptors that, unlike
+ * Negtrin and Postrin interoceptors are specialized intrinsic interoceptors that, unlike
  * neutral interoceptors, have activation thresholds for different response levels 
  * (indication, alert, and overload). These thresholds allow them to trigger graduated 
  * responses based on stimulus intensity.
  * 
- * While neutral interoceptors simply record a binary state or basic value, pain and
- * pleasure interoceptors can model complex sensory responses with multiple activation
- * levels, similar to biological pain/pleasure responses. Each threshold represents a
- * different level of urgency or intensity in the sensory input.
