\n(AL), the first olfactory neuropil in the insect brain. In the AL, ORNs make synaptic contacts
\nwith: i) projection neurons (PNs) that send olfactory information to other brain areas; and ii)
\nlocal interneurons (LNs) that form a dense network of lateral interactions within the AL.
\nFunctional studies indicate that this network reshapes sensory information, presumably to
\nenhance perception of meaningful odors. In this project we investigate the role of GABAergic
\ninteractions in relation to learning dependent neural plasticity in the AL. Our previous work
\nshowed that the representation of a mixture in the AL changes after aversive conditioning,
\nmaking the learned component more salient. Now we are performing aversive olfactory
\nconditioning using a T-maze. We train flies to associate an electric shock with an odor that they
\nhave to avoid during the test session. To study how animals perceive mixtures, we evaluate
\nthe ability of the animals to detect the presence of the learned odor immersed in a binary
\nmixture. To do that, we test the flies with two stimuli: a novel odor versus a mixture that
\ncontains the associated odor. Future experiments are directed to evaluate whether blocking
\nthe LNs activity impairs learning dependent changes and the ability to detect learned
\ncomponent.<\/p>\n","protected":false},"excerpt":{"rendered":"
