Exploring The Structural And Functional Effects Of Pediatric Hydrocephalus On The Hippocampus, Lili Meng
Exploring The Structural And Functional Effects Of Pediatric Hydrocephalus On The Hippocampus, Lili Meng
Undergraduate Student Research Internships Conference
Hydrocephalus is one of the most common pediatric neurological problems that requires brain surgery in children. Pediatric hydrocephalus is characterized as an abnormal cerebrospinal fluid (CSF) buildup in the brain’s ventricles due to ineffective CSF reabsorption. When this fluid builds up in these cavities, it increases intracranial pressure and has a direct mass effect on the surrounding brain tissue and structures. Ultimately, various functions are affected including—but not limited to—vision, learning, memory, motor control, and hearing. Despite current literature suggesting that hydrocephalus may be associated with reduced hippocampal volume among rats and human adults, findings remain limited in the human …

Medical Student Research Symposium
Long-term potentiation (LTP), the selective strengthening of specific synapses based on recent activity, has widely been accepted as the biological mechanism responsible for learning and memory. N-methyl-D-aspartate receptors (NMDARs) play a critical role in LTP, which when activated, result in a surge of postsynaptic intracellular calcium levels. The calcium rise during LTP results in the activation of Ca2+/calmodulin-dependent kinase II alpha (CaMKIIa), which consequently enacts multiple cellular effects that ultimately result in the strengthening of synaptic connections. Previous work has examined the effects of CaMKIIa overexpression in rat hippocampi on spatial memory, however, significant but limited improvement in …
The Effects Of Astrocytic Derived Insulin-Like Growth Factor (Igf-1) On Cognition And Astrocytes, Destiny Wilson
The Effects Of Astrocytic Derived Insulin-Like Growth Factor (Igf-1) On Cognition And Astrocytes, Destiny Wilson
Honors Theses
Insulin-like growth factor 1 (IGF-1) is a neuroendocrine signaling hormone that plays a vital role in growth and development, as well as learning and memory. Inhibition of this hormone results in cognitive impairments like those seen with age-related decline. While a majority of research has focused on the role of IGF-1 on neurons, the role of astrocytes still needs to be explored. Our research investigates how astrocytes and cognition are affected as a result of direct regulation of localized IGF-1 production in early development and after puberty. Preliminary studies in our laboratory established a connection between IGF-1 and glial fibrillary …
Sex Differences In Hippocampal O-Glcnacylation Of The Adult Mouse Brain, Makenzie Johnson
Sex Differences In Hippocampal O-Glcnacylation Of The Adult Mouse Brain, Makenzie Johnson
Selected Honors Theses
The hippocampus is a structure in the brain crucial for learning and memory. This occurs by synaptic remodeling known as long term potentiation and long term depression. Modifications of proteins in the hippocampus can affect its function. One of these modifications is the addition of O-linked β-N-acetylglucosamine, also known as O-GlcNAc. This is a sugar produced from glucose by the hexosamine biosynthetic pathway that is reversibly added onto serine and threonine residues of proteins by O-GlcNAc Transferase, or OGT. It is reversibly removed from these residues by O-GlcNAcAse, or OGA. This modification has been implicated in diabetes, cardiac dysfunction, and …
