Interhemispheric Communication And Lateralization In The Mouse Hippocampus, Jake Jordan
Interhemispheric Communication And Lateralization In The Mouse Hippocampus, Jake Jordan
Dissertations, Theses, and Capstone Projects
The hippocampus is essential for memory and spatial navigation. Many theories have been proposed to explain how the hippocampus contributes to cognition; however, none has fully explained relevant neurophysiological and behavioral data. Hemispheric lateralization of hippocampal function has been reported in humans and in rodents, and lateralization of hippocampal neural circuitry has been reported in rodents. Most theories of hippocampal function fail to consider the hippocampus as a bilateral structure with hemispheric differences. Further, proposed theories of hippocampal lateralization have their own limitations in explaining empirical data concerning left/right function. Little is known about communication between the hippocampi across hemispheres. …
The Role Of H3k4 Methyltransferases In Drosophila Memory, Nicholas Raun
The Role Of H3k4 Methyltransferases In Drosophila Memory, Nicholas Raun
Electronic Thesis and Dissertation Repository
Gene transcription required for long-term memory requires the modification of histones. However, there are still many uncertainties about the identity and spatial expression of genes regulated by histone modifications during memory related processes. In this project I examined the role of Drosophila melanogaster methyltransferases Set1 and trx in courtship memory. Genetic knockdown of Set1 and trx in the mushroom body (MB) revealed that Set1 was necessary for short- and long-term memory, while trx was only required for long-term memory. Transcriptional profiling of MBs following trx-knockdown revealed expression changes in MB-enriched genes and genes involved in RNA processing. Among the …
Behavioral And Molecular Analysis Of Memory In The Dwarf Cuttlefish, Jessica M. Bowers
Behavioral And Molecular Analysis Of Memory In The Dwarf Cuttlefish, Jessica M. Bowers
Electronic Theses and Dissertations
Complex memory has evolved because it benefits animals in all areas of life, such as remembering the location of food or conspecifics, and learning to avoid dangerous stimuli. Advances made by studying relatively simple nervous systems, such as those in gastropod mollusks, can now be used to study mechanisms of memory in more complex systems. Cephalopods offer a unique opportunity to study the mechanisms of memory in a complex invertebrates. The dwarf cuttlefish, Sepia bandensis, is a useful memory model because its fast development and small size allows it to be reared and tested in large numbers. However, primary literature …
