Networks connecting the amygdala and prefrontal cortex are vital for linking emotions and thinking. Specific pathways between the amygdala and orbitofrontal cortex are essential for forming and using reward expectations to guide behavior.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Affective Science

Background:

  • The amygdala and prefrontal cortex form a critical network linking emotion and cognition.
  • Interconnections between these regions are implicated in motivated behavior.

Purpose of the Study:

  • To elucidate the role of amygdala-orbitofrontal cortex connections in reward expectancy.
  • To understand how these networks guide goal-directed behavior.

Main Methods:

  • Review of converging evidence from rodents, humans, and non-human primates.
  • Analysis of neural pathways and their functional significance.

Main Results:

  • Interconnections between the basolateral amygdala and orbitofrontal cortex are crucial.

  • These pathways are essential for forming expectancies of reinforcers.

    • Conclusions:

    • The amygdala and orbitofrontal cortex network is fundamental for linking affect and cognition.
    • This network underpins the use of expectancies in goal-directed behavior.
