Development And Characterization Of A Novel, Genetically- Encoded Sensor To Image Sonic Hedgehog Signaling In Functional Circuits, Sonia Bernal
Dissertations, Theses, and Capstone Projects
Dynamic neurotransmitter and neuromodulator signaling in functional circuits is the neural substrate of animal behavior and cognition. The study of said circuits requires tools with sufficient spatiotemporal dynamics that can probe complex signaling patterns and decode their functional relevance by coupling the signal to behavioral output, ideally in awake, behaving animals. Much is known about the role of classical neurotransmitters such as dopamine in behavior, but a wide variety of peptides and small molecules also regulate neuronal transmission. One of these is Shh, whose presence has been observed in a variety of brain regions known to modulate movement, perception, and …
