01 Dopaminergic circuits in Drosophila
Sihui Jin
Dopamine is an important neurotransmitter in mammals
Why we choose Drosophila as a model system for the study of dopamine
The brain of Drosophila melanogaster is comprised
of 100,000 neurons.
Dopamine regulates the same behavioral functions
both in mammals and flies.
Drosophila genes can be replaced by their human
orthologs.
The genetic tool box is useful.

The DA neuronal system in larval CNS
Maria Monastirioti. 1999
Three bilateral clusters, consisting of 4–6 neuronal
perikarya each, are located in DM, DL1, and DL2 positions
in the brain lobes.
The axonal projections of most of these DA cells extend
within the ipsilateral brain lobe following common axonal
tracts.
Sb, Abu, Th, ThL and AbL form two lateral rows,
symmetrically placed along the thoracic and abdominal
ganglia.

CS: conditioned stimulus
Reinforcement learning (aversive ) In drosophila
Octopamine is necessary for the
acquisition of sugar memory
DA is necessary for acquisition but not
retrieval of electric shock memory
Reinforcement learning (aversive ) In drosophila
Reinforcement learning (aversive ) In drosophila
A subset of 12 DA neurons was identified in the PPL1 cluster could implant aversive memories

Reinforcement learning (reward ) In drosophila
DA signaling is functionally downstream of OA in appetitive memory processes
0273- and 0104-GAL4 lines express in
subsets of PAM-DA neurons
Reinforcement learning (reward ) In drosophila
Thermo-activation with DDC-GAL4 induces appetitive memory
Reinforcement learning (reward ) In drosophila
The PAM cluster neurons signal
reward for olfactory memory
The PAM neurons convey the reward
signal to the MB
Reinforcement learning (reward ) In drosophila
Scott Waddell. 2010
Q: Why is dopamine considered a reward signal in mammal but a aversive signal in
drosophila?
The prior conclusion that DA was only required for aversive learning was drawn
from studies using a TH-GAL4 line that does not express in all of the fly’s DA
neurons
The DA neurons that are omitted by TH-GAL4 are those in the PAM cluster that
signal rewarding reinforcement
A:
Q&A
Addiction In drosophila
Ethanol is both aversive and rewarding to flies
Addiction In drosophila
Dopamine is required for expression of ethanol reward

Addiction In drosophila

The mushroom body is required for aversion and preference
Addiction In drosophila

administration of low doses of cocaine and
nicotine
