Activation of D1 dopamine
receptors activates the Gs
signalling cascade which
leads to increased cAMP.
Reward Pathway
Activation of Alpha-1A
receptors activates the Gq
signalling cascade which has
a variety of excitatory
effects on neurons in the
brain.
Norepinephrine activates
neurons in the locus
coeruleus which activates
the limbic system. The
limbic system is implicated
in emotions and cognition.
Increased cAMP results in
increased neural
excitability in the Limbic
System which helps regulate
behaviour and emotional
responses.
Limbic System
Emotions
Cognition
Cytosol
Presynaptic Neuron
The inhibition of
norepinephrine reuptake
receptors by Duloxetine
causes more norepinephrine
to accumulate in the
synapse, causing the
continual activation of the
alpha-1A adrenergic receptor
Synapse
Synaptic Vesicle
Dopamine is produced in the
Ventral Tegmental Area of
the brain
Norepinephrine is produced
in the locus coeruleus
Frontal Cortex
Cytosol
Increased dopamine activates
D1 dopamine receptor in the
