The current pathological confirmation of the diagnosis of Alzheimer's disease (AD) is still based on postmortem identification of parenchymal amyloid beta (Aβ) plaques, intra-neuronal neurofibrillary tangles, and neuronal loss. The memory deficits that are present in the early stages of AD are linked to the dysfunction of structures in the entorhinal cortex and limbic system, especially the hippocampus and amygdala. Using the CRND8 transgenic mouse model of amyloidosis, which over-expresses a mutant human amyloid precursor protein (APP) gene, we evaluated hippocampus-dependent contextual and amygdala-dependent tone fear conditioned (FC) memory, and investigated the relationship between the fear memory indices and Aβ plaque burden.

Slide image modification software that allows the user to adjust the magnification, compare slides, pan and zoom, annotate specific areas, and perform image analysis of digital slides. Users can create macros and algorithms to automate analysis and create plots, respectively.
View all literature mentionsA video-based system to detect animal movement in fear conditioning experiments, as well as movements in learned helplessness experiments. FreezeFrame can detect animal movements (as small as 1mm) and actions, including grooming, sniffing, turning, and rearing. It can also collect and process data for learned helplessness experiments, such as Tail Suspension and the Porsolt Forced Swim Test. This software can monitor animals for up to 15 times per second.
