Neurotransmitter Dysfunction and its Impact on Learning and Behavior

Dopamine neurons in the ventral tegmental area (VTA) are responsible for reward prediction error
Amygdala neurons play a role in aversive prediction error
Medial prefrontal cortex regulates the expression of learned behavior after extinction
Pre-limbic cortex activates reward seeking, fear conditioning, and drug seeking
Infra-limbic cortex switches off fear learning and promotes extinction learning
Inactivation of pre-limbic cortex inhibits the expression of learned fear
The amygdala is crucial for aversive prediction error and inhibiting its neurons prevents learning
VTA dopamine neurons encode reward prediction error
Blocking is a learning paradigm where no learning occurs due to the absence of prediction error
Neurotransmitters are released from the presynaptic terminal through exocytosis and bind to postsynaptic receptors
The medial prefrontal cortex is necessary for the expression of learned fear and inhibition during extinction promotes retrieval of extinguished fear
Dysfunctions in the monoamine neurotransmitter system are associated with schizophrenia and depression

Test your knowledge on neurotransmitter dysfunction and its impact on learning and behavior. Learn about the role of dopamine neurons, amygdala neurons, and various cortical regions in reward prediction, aversive prediction, fear learning, and extinction. Understand how dysfunctions in the monoamine neurotransmitter system can be linked to mental illnesses like schizophrenia and depression.
