Vasopressin (VP) and Oxytocin (OT) are neuropeptides produced in the hypothalamus and expressed in the cerebrum and pituitary gland of the brain. Studies of VP and OT have long demonstrated their influence on social behaviors in mammals. Comparative analyses of these neuropeptides and in-depth analyses in non-mammalian species may reveal the specific mechanistic roles these hormones play in social behavioral functioning. The acquisition of complex behavioral patterns involves sensory-motor functions. How social interactions modulate sensory-motor mechanisms that promote complex behavior acquisition and maintenance can be well study in vocal learning birds. Here, in addition to reviewing the pertinent literature, I …
Understanding How Sequence Differences Among Glutamate Transporters Might Contribute To Their Differential Function In Glutamate Clearance In C. Elegans, Irving Estevez
Dissertations and Theses
In the nervous system, high circuit resolution requires efficient post-signaling clearance of the neurotransmitter. Glutamate-mediated neurotransmission involves the release of glutamate (Glu) into the synaptic cleft by the presynaptic cell and binding to glutamate receptors (GluR) on the postsynaptic cell, leading to activation of a signal transduction cascade. Neurotransmission is eventually terminated by Glu uptake via glutamate transporters (GluT). Inefficient Glu clearance is detrimental to precise rapid signaling, can lead to blurring of circuit resolution by inadvertent Glu spillover to nearby circuits, and may even be neurotoxic. While classical views depict synapses as insulated by glia, recent technological advances show …
Effects Of Weak Electric Fields On Long-Term Synaptic Plasticity, Gregory Kronberg
Effects Of Weak Electric Fields On Long-Term Synaptic Plasticity, Gregory Kronberg
Dissertations and Theses
Transcranial direct current stimulation (tDCS) is a technique where a weak direct electrical current is applied to the scalp with the goal of stimulating the brain. There is tremendous interest in the use of tDCS for treating brain disorders and improving brain function. However, the effects of tDCS have been highly variable across studies, leading to a debate over its efficacy. A major challenge is therefore to design tDCS protocols that yield predictable effects, which will require a better understanding of its basic mechanisms of action. One commonly discussed mechanism is that tDCS may alter synaptic plasticity, but the biophysics …
