The McGill-Thy1 APP mouse is a triple transgenic model of Alzheimer disease, which has the mutant amyloid precursor protein to synergistically over-produce amyloid beta plaques. These mice exhibit visuo-spatial learning impairment at 3 months of age and memory impairment at 10-13 months of age in the Morris water maze. To extend these findings mice at 3, 5, and 7 months of age were tested on the Barnes maze. Non-Transgenic and Transgenic mice showed improvement during acquisition. However, 3 month and 5 month McGill Thy1- APP mice showed impaired acquisition learning while 7 month showed a learning and memory deficit compared …

Theta oscillation is the largest extracellular synchronous signal that can be recorded from the mammalian brain. It is known to influence information retention in the hippocampus, which plays a key role in declarative memory, recognition memory, working memory, and spatial memory. The theta oscillation field frequency is between 3 and 12 Hz and is present during exploratory behavior and sleep in rodents. Theta rhythm in the hippocampus is postulated to be produced by the rhythmical activity of pacemaking cells in the medial septumvertical limb of the diagonal band of Broca (MS-vDBB). Previous work in our laboratory demonstrated the existence of …

Stroke is the fifth leading cause of death in the United States and a major cause of long-term disability in industrialized countries. The core region of an ischemic stroke dies within minutes due to activation of necrotic pathways. Outside of this core region is the penumbral zone, where some perfusion is maintained via collateral arteries. Delayed cell death occurs in this area due to the triggering of apoptotic mechanisms, which expands the ischemic injury over time. The cellular and molecular events that produce the expansion of the ischemic core continue to be poorly understood. The increases in the amyloid precursor …
