The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl
The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl
Senior Theses and Projects
Oxygen levels tend to remain at a steady state concentration in the Earth’s atmosphere, yet in some bodies of water, they can fluctuate and decrease drastically. Many organisms that inhabit the swamps, lakes, streams, and parts of the ocean where this occurs have evolved adaptations to manage this environmental uncertainty and continue normal oxygen consumption. The Lwamunda swamp in Uganda is chronically hypoxic, yet it is home to many species, including the electric fish Petrocephalus degeni. P. degeni are unusual by nature of their immense brain, and the Lwamunda swamp appears ill-suited for maintaining this large, metabolically active organ. To …
The Effects Of Mindfulness Meditation On Rumination In Depressed People, Rachel A. Sluder
The Effects Of Mindfulness Meditation On Rumination In Depressed People, Rachel A. Sluder
Honors Theses and Capstones
Mindfulness meditation is a practice of focus, awareness, and non-judgmental acceptance of one's thoughts (Deyo et al., 2009; Kenny et al., 2007). Rumination is a maladaptive pattern of thought that is common in people with depression and other mood disorders. It can lead to further episodes of depression, and can be very destructive in that way (Nolen-Hoeksema, 2008). This paper reviews several studies on mindfulness meditation, depression, and rumination, with a focus on certain areas and phenomena such as alpha asymmetry (Keune et al 2013) and gamma band activity (Berkovich-Ohana et al., 2012). Modalities such as fMRI and EEG are …
The Effects Of Bfgf Treatment In The Aged Brain Following Traumatic Brain Injury, Michael Zeigler
The Effects Of Bfgf Treatment In The Aged Brain Following Traumatic Brain Injury, Michael Zeigler
Theses and Dissertations
The mature mammalian brain continually generates new neurons in the subventricular zone and hippocampus throughout life. Adult neurogenesis in the hippocampus is associated with hippocampal-dependent learning and memory function. During aging, this endogenous neurogenic potential is reduced which is accompanied by decreased cognitive function seen in the aging population. We have previously found that the injured adult brain shows heightened levels of endogenous neurogenesis and this response is associated with innate cognitive recovery. We have also found that basic fibroblast growth factor (bFGF), a potent neurotrophic polypeptide, can enhance injury-induced hippocampal neurogenesis and improve cognitive recovery following TBI. In this …
Cross-Modal Projections From Auditory To Visual Cortices In The Ferret, Meng Y. Wang
Cross-Modal Projections From Auditory To Visual Cortices In The Ferret, Meng Y. Wang
Theses and Dissertations
Recent studies have shown that neuronal connections occur between primary auditory and visual cortices of the primate (Falchier et al., 2002; Rockland and Ojima, 2003), and it has been suggested that these projections are involved in multisensory processing in these lower-level, core areas of cortex. The present study was conducted to determine if similar connections occur in other higher mammals such as carnivores (ferrets; Mustela putorius). Large injections of sensitive neuroanatomical tracer were placed within the core areas of auditory cortex in 3 ferrets. After transport and processing, labeled axon terminals were found not in primary visual cortex, but in …
