Microscopy Development &amp; Applications:<\/strong> we refine and integrate the imaging modalities of Light Sheet Microscopy and Light Field Microscopy, in conjunction with other standard techniques, to expand the Dynamic System Imaging toolset, to push further the resolution, speed, depth, and overall informational content of biological imaging. We validate the capabilities of our imaging tools, often through multi-disciplinary collaborations, with a diverse set of applications \u2013 such as quantifying developmental morphogenesis in live embryos, characterizing the glucose-induced calcium dynamics in ex-vivo pancreatic islets, and observing the whole-brain functional activity of a live animal (see below).<\/p>\n<p style=\"text-align: left;\"><strong>2. Zebrafish Neuroscience:<\/strong> we aim to uncover how complex behaviors \u2013 such as sleep, learning, and cognition \u2013 emerge from and operate within the seemingly simple nervous system of days-old zebrafish larvae. Despite having a brain smaller than a chia seed, these semi-transparent animals possess a sophisticated behavioral repertoire, and thus provide an ideal platform to study how the neural components \u2013 molecules, synapses, neurons, circuits \u2013 interact together to produce brain functions. Using our Dynamic System Imaging toolset, we develop custom-built imaging platforms to enable real-time observation of the neural components across the intact, living zebrafish brain as the animal engages in naturalistic behaviors. While focused on understanding fundamental processes, our work leverages the conserved neurobiology between zebrafish and humans to provide valuable translational insights into neurological health and disease.<\/p>\n\n\n\n<\/div>\n\n\n  <\/div><\/div>\n\n\n\n        \n          \n          \n  \n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--editorial-cards \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--editorial-cards\"\n    \n      >\n\n    \n  \n      <div class=\"cards-container\">\n      \n        <div class=\"card\">\n\n          \n          <div class=\"text-container\">\n            \n                            <h3>\n                                      <a href=\"https:\/\/dornsife.usc.edu\/dsig\/members\/\" >\n                  \n                    People\n\n                                      <\/a>\n                                  <\/h3>\n            \n                      <\/div>\n\n\n        <\/div>\n      \n        <div class=\"card\">\n\n          \n          <div class=\"text-container\">\n            \n                            <h3>\n                                      <a href=\"https:\/\/dornsife.usc.edu\/dsig\/content-2\/\" >\n                  \n                    Research &#8211; Microscopy Development &#038; Applications\n\n                                      <\/a>\n                                  <\/h3>\n            \n                      <\/div>\n\n\n        <\/div>\n      \n        <div class=\"card\">\n\n          \n          <div class=\"text-container\">\n            \n                            <h3>\n                                      <a href=\"https:\/\/dornsife.usc.edu\/dsig\/research-zebrafish-neuroscience\/\" >\n                  \n                    Research &#8211; Zebrafish Neuroscience\n\n                                      <\/a>\n                                  <\/h3>\n            \n                      <\/div>\n\n\n        <\/div>\n          <\/div>\n  \n\n  <\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":9,"featured_media":205,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-4","page","type-page","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 -
