Pharmaceutical And Natural (Exercise) Mechanisms To Mitigate The Negative Impact Of Ptsd And Chronic Stress On Synaptic Plasticity And Memory, Roxanne M. Miller Nov 2017

Pharmaceutical And Natural (Exercise) Mechanisms To Mitigate The Negative Impact Of Ptsd And Chronic Stress On Synaptic Plasticity And Memory, Roxanne M. Miller

Theses and Dissertations

Synapses can be altered due to experiences in a process called synaptic plasticity, which causes memory formations. Synapses can be strengthened through methods known as long-term potentiation (LTP) or weakened through long-term depression (LTD). Stresses can cause changes by altering synapses through either LTP or LTD. Rats were used to study the effects of post-traumatic stress disorder (PTSD)-like symptoms and a prophylactic treatment using pharmaceuticals. The first model used was the single prolonged stress (SPS) with two weeks of chronic light, which was not as effective for causing changes in synaptic plasticity. The second model, seven days of social defeat …

Modulation Of Synaptic Plasticity: Endocannabinoids And Novel G-Protein Coupled Receptors Expression And Translational Effects In Interneurons, Katrina M. Hurst Jul 2017

Modulation Of Synaptic Plasticity: Endocannabinoids And Novel G-Protein Coupled Receptors Expression And Translational Effects In Interneurons, Katrina M. Hurst

Theses and Dissertations

Learning and memory are important processes that occur in the brain. The brain is comprised of neurons that make connections with each other known as synapses. Synaptic plasticity is widely believed to be the physiologic mechanism by which learning and memory occur. Synapses can either be strengthened through a process known as long-term potentiation (LTP) or weakened through long-term depression (LTD). The area of the brain that is most studied for its role in learning and memory is the hippocampus, which has been shown to be involved in memory consolidation. The detection of endocannabinoids and their receptors has opened a …
