   My research interest is to understand the neural circuits and molecular mechanisms

 contribute to memory. Drosophila melanogaster has contributed to this insight, fly can

 be taught to associate an odor, conditioned stimulus (CS), with a punitive foot shock,

 unconditioned stimulus (US). Fly memory can be genetically and behaviorally dissected into

 several different phases depending on the training protocols. In our prior studies, we

 have identified the NMDA receptors play the exclusive roles for different types of memory

 consolidation in Drosophila (Xia S et al., 2005 Current Biology, Wu CL et al., 2007 Nature

 Neuroscience, Wu CL et al., 2008, Journal of Neurogenetics).

   In our recent studies, we have revealed the gap junctions involved in specific type of

 intermediate-term memory formation. Gap junctions are important for normal brain functions

 but their contribution to memory has not been well characterized. We showed two modulatory

 neurons, i.e. the anterior paired lateral (APL) and dorsal paired medial (DPM) neurons,

 form gap-junctional communication in the mushroom body (MB), the learning and memory center

 in the Drosophila brain. Following disruption of such gap junctions with RNAi-mediated

 knockdowns of inx7 and inx6 in the APL and DPM neurons, respectively, we found that flies

 showed normal olfactory associative learning and intact Anesthesia-Resistant Memory (ARM)

 but could not form three-hour Anesthesia-Sensitive Memory (ASM). Our results indicate

 the heterotypic gap junctions between the APL and DPM neurons are an essential part of the

 MB circuitry for ASM, suggesting that a recurrent neural circuit, consisting of APL, DPM

 and MB neurons, may stabilize ASM inside the MB (Wu CL et al., 2011 Current Biology).

   More interestingly, we also found that chemical neurotransmission from the APL neuron

 is necessary for ARM consolidation rather than ASM. We identified the APL neurons are

 tyramine, Tβh, and octopamine immunopositive. Octopamine is the counterpart of human

 norepinephrine and may also play the role for memory formation. With an adult-stage-specific

 RNAi knockdown of Tβh in the APL neurons or Octβ2R octopamine receptors in the MB α’/β’

 Kenyon cells (KCs) impaired ARM. Our data imply octopamine released from the APL neurons

 acts on MB α’/β’ KCs via Octβ2R receptor to modulate Drosophila ARM formation. Together

 with previous findings suggest that two parallel ARM pathways, serotoninergic DPM-MB α/β

 KCs and octopaminergic APL-MB α’/β’ KCs, exist in the Drosophila brain (Wu CL et al.,

 2013 Current Biology).
