Student Theses and Dissertations
The gastro-intestinal tract is the most extensive mucosal surface in mammals and harbors the most numerous immune cell reservoir as well as a complex and autonomous nervous system. The GI tract is continuously exposed to foreign antigen and potentially toxic chemicals through the ingestion of food. In addition, the lumen of the human GI tract is populated with approximately 1013 bacteria, which is equivalent to the number of cells in the entire human body (Sender et al., 2016). The intestinal microbiome, which aids in host metabolism, represents a diverse population of microorganisms separated from the inside of the body by …
Representations Of Reward And Movement In Drosophila Dopaminergic Neurons, Aryeh Zolin
Representations Of Reward And Movement In Drosophila Dopaminergic Neurons, Aryeh Zolin
Student Theses and Dissertations
The neuromodulator dopamine is known to influence both immediate and future behavior, motivating and invigorating an animal’s ongoing movement but also serving as a reinforcement signal to instruct learning. Yet it remains unclear whether this dual role of dopamine involves the same dopaminergic pathways. Although reward-responsive dopaminergic neurons display movement-related activity, debate continues as to what features of an individual’s experience these motor-correlates correspond and how they influence concurrent behavior. The mushroom body, a prominent neuropil in the brain of the fruit fly Drosophila melanogaster, is richly innervated by dopaminergic neurons that play an essential role in the formation of …
