Hacking Brain Development to test models of sensory coding
Animals can discriminate myriad sensory stimuli but can also generalize from learned experience. You can probably distinguish the favorite teas of your colleagues while still recognizing that all tea pales in comparison to coffee. Tradeoffs between detection, discrimination, and generalization are inherent at every layer of sensory processing. During development, specific quantitative parameters are wired into perceptual circuits and set the playing field on which plasticity mechanisms play out. I will discuss my lab's work to understand the development of these quantitative wiring parameters in the expansion layer of arthropods, the mushroom body. We use our knowledge of developmental wiring mechanisms to modify wiring parameters and assess the functional and behavioral consequences in odor perception and learning.
