The monosynaptic stretch reflex circuit is one of the simplest circuits of the central nervous system. We studied the connection between Ia proprioceptive afferents and motor neurons that comprise the circuit, by stimulating the dorsal root and recording from the ventral root of the fourth lumbar spinal nerve. In our study, we analyzed the status of neurotransmission in the stretch reflex circuit in postnatal PV-cre; munc18-1 lox/lox conditional mutant mice. Munc18-1 is responsible for synaptic vesicular release in neurons. In the PV-cre; Munc18-1 lox/lox mutants we use, Munc18-1 is only knocked out in proprioceptive afferents and A-beta somatosensory afferents, both …

Silver nanoparticles (AgNPs) and ionic silver (Ag+) are known to be broad-spectrum antimicrobial agents. Recent studies show these agents may be an alternative to the most widely used drinking water disinfectant, chlorine. Chlorine is a toxic industrial chemical with a lethal concentration of 430 ppm after 30 minutes. Additionally, chlorine can react with naturally occurring materials to produce a number of disinfection byproducts such as chloroform and trihalomethanes. Some of these byproducts pose cancer risks in addition to other negative impacts to human health. These would be eliminated with the use of Ag+ or AgNPs. The main goal of this …

Computational modeling has long been used in neuroscience as a supplement to more traditional experimental techniques, as it provides some advantages in terms of the level and detail of control available over the system being studied. At the same time, modeling has significant disadvantages by virtue of adding additional uncertainty to results and forcing the definition of potentially unclear physiological mechanisms. Nevertheless, modeling can provide useful insights when carefully defined and constrained. In this thesis, a model of the a-MN pool innervating the cat medial gastrocnemius was constructed. This model was then used to address two major questions, one regarding …
