Book Description
Learning and memory are intensively studied topics in modern brain and cognitive science. Drosophila has been used in the study of visual learning and memory for approximately the past 20 years. In this chapter, we discuss the architecture and function of fruit fly’s visual system, which provides it with the sensory and neural substrate for color, motion, and shape vision. We then discuss visual learning, visual memory, invariant pattern recognition, selective attention, choice behavior, context generalization, spatial learning, habit formation, cross-modal memory transform, and synergism. Finally, we address the issues of collective learning and social decision making.

Book Description
How does an animal know where it is, and where it is going? While the impressive navigation abilities of ants, bees, wasps, and other insects clearly demonstrate that insects are capable of visual place learning, little is known about the underlying neural circuits that mediate these behaviors. Drosophila melanogaster is a powerful model organism for dissecting the neural circuitry underlying complex behaviors, from sensory perception to learning and memory. Flies can identify and remember visual features such as size, color, and contour orientation. However, the extent to which they use vision to navigate and recall specific locations remains unclear. In this dissertation, I will : 1) describe the development of a novel place learning assay for investigating spatial memories in Drosophila ; 2) present evidence that fruit flies are capable of forming and recalling spatial memories ; 3) demonstrate that neurons in the central complex are necessary for visual place learning and 4) show that silencing these cells specifically impairs place learning without affecting other sensory or motor systems. Together, these studies reveal distinct neuroanatomical substrates for spatial versus non-spatial learning, and substantiate Drosophila as a powerful model for the study of spatial memories.

Book Description
The small fruit fly, Drosophila melanogaster, has for over a century now had a large impact on biological and biomedical research; however, our knowledge of the fly brain has lagged significantly behind our understanding of other aspects of its development, physiology, and function. In The Making and Un-Making of Neuronal Circuits in Drosophila, innovative expert neuroscientists in the field present the ideas and concepts behind the methods, tools, and tricks that are currently being utilized to decode the secrets of this valuable insect’s brain. Focused on the concept of a neuronal circuit, defined as a series of synaptically connected neurons subservient to a particular behavioral modality, this volume contains chapters dealing with anatomical analysis with a focus on cellular and sub-cellular morphologies. These detailed approaches fall under the headings of “Physiology” and “Behavior”, conveniently divided the book into two sections. Written in the easy-to-follow Neuromethods series format, this work provides the kind of detailed description and implementation advice that is crucial for getting optimal results. Inventive and accessible, The Making and Un-Making of Neuronal Circuits in Drosophila provides the information and tools necessary to carry out current experiments and, more importantly, further advance the progress of the Drosophila neurobiology field and neurobiology in general.
