The maintenance of a range of cognitive tasks in male Drosophila, including but not limited to olfactory learning ability, was significantly reduced after 100 generations of enforced monogamy (Anderson ... Extension of these methods to olfactory conditioning will allow assessment of olfactory learning in a quantitative and unbiased fashion and facilitate the search for higher order learning about odors. ...

 have addressed this question in Drosophila larvae, an insect model that has become popular for the study of associative olfactory learning. ... Thus, these monoamines do not up-regulate or down-regulate these behaviours in a non-specific way, rather they act specifically as an instructive element in associative learning phenomena. ...doi:10.1016/j.cub.2006.09.021 pmid:17055975 fatcat:nvefy5u2nbenfbpt7ahy7h3e74
Several animal models have been used in the study of memory and cognition. ...

The honeybee olfactory system is a well-established model for understanding functional mechanisms of learning and memory. ... Thus, our model explains several-but not alltypes of associative olfactory learning and generalization by a few neural layers of odour processing in the l-ALT. ... and non-elemental olfactory learning is still unknown. ...doi:10.1371/journal.pcbi.1005551 pmid:28640825 pmcid:PMC5480824 fatcat:2sj6urpocrf2jkravdb6rfunja
It was argued whether a model is really a model or a description of the data, and if it was just a description then it could not be tested. ... For example, a piece of limb was removed and the reoccurrence of the missing part was described. On the basis of the final product of regeneration, models were developed. ... It was argued whether a model is really a model or a description of the data, and if it was just a description then it could not be tested. ...doi:10.1016/j.cub.2006.01.038 pmid:16461264 fatcat:5mlpme7aq5eozlr32jqhncajde
The last 30 years have witnessed tremendous progress in elucidating the basic mechanisms underlying a simple form of olfactory learning and memory in Drosophila. ... The application of the mutagenic approach to the study of olfactory learning and memory in Drosophila has yielded insights into the participation of a large number of genes in both the development of critical ...

Animals smelling in the real world use a small number of receptors to sense a vast number of natural molecular mixtures, and proceed to learn arbitrary associations between odors and valences. ... Moreover, introducing any order in the expansive projections degrades the ability to recall the learned associations in the presence of noise. ... To construct each mixture composition vector x, we set a small number K of its elements to be non-zero (where K specifies the complexity of the mixture). ...doi:10.3389/fncom.2022.917786 pmid:36003684 pmcid:PMC9393645 fatcat:bv5rsfyoqjb2zjfgryk3qf6x2u
Using a DD2R-RNAi transgenic line, we have examined the role of DD2R, expressed in dopamine neurons (i.e., the presynaptic DD2R autoreceptor), in larval olfactory learning. ... The function of postsynaptic DD2R expressed in mushroom body (MB) was also studied as MB is the center for Drosophila learning, with a function analogous to that of the mammalian hippocampus. ...

Colvin for valuable inputs on previous versions of this manuscript. ...doi:10.3390/biology3040831 pmid:25422852 pmcid:PMC4280513 fatcat:npwqljw36fbz5bbbk2b6z5aida
We discuss how technologies in the fly model, combined with a high degree of molecular and physiological conservation between flies and mammals, highlight the Drosophila system as an ideal model to study ... Here, we review studies where the use of well-established assays to study mechanisms of learning and memory in Drosophila has permitted insights into molecular mechanisms underlying IDs. ...

While the role of dopamine in olfactory learning in Drosophila is well described, the function of serotonin and its downstream receptors on Drosophila olfactory learning remain largely unexplored. ... In summary, our results establish a critical, and previously unknown, role of d5-HT7 in olfactory learning. ... Dolan for their help with the larval learning experiments and Dr. R.A.

In adult Drosophila it was shown that memory formation after aversive Pavlovian conditioning includes-besides other forms-a labile short-term component that consolidates within hours to a longer-lasting ... Compared to adult Drosophila, memory formation was only sporadically analyzed at its larval stage. Here we deconstruct the larval mnemonic organization after aversive olfactory conditioning. ...

Here, we examine the features which we believe make Drosophila melanogaster a model apt to study the role of the circadian clock in psychiatric disease. ... In addition, Drosophila has a rather complex nervous system, which shares much at the cell and neurobiological level with humans, i.e., a tripartite brain, the main neurotransmitter systems, and behavioral ...

Drosophila models of human learning and memory disorders One of the outcomes of sequencing the genomes of hu- mans and model organisms was the high degree of simi- larity in the proteins they encode, and ... However, it is un- clear whether such a mechanism, or misregulation of Raf activity and MAPK signaling is responsible for compro- mised MB-dependent olfactory learning and memory. ...
