Research Abstract

deta / A4 arotein-like immunoreactivity was observed in the form of granular structures in various regions, including the medial septum, cerebral cortex, hippocampus, and so on. These increased in number with aging, predominantly in SAM-P/8 with deficits in lemory defici
The severity of deficits in learning and memory closely correlated with the total area and number of vacuoles in magnocellular reticular formation (MGRF) of brain stem. MGRF lesioned SAM-R/1 mice showed a severe deterioration in passive avoidance tasks and an impairment in the acquisition stage of active avoidance performance.
An inbred SAM-P/10 strain has been established as a model of agerelated brain atrophy. Morphometric studies showed that frontal cortex including prefrontal cortex, other neocortical regions, posterior piriorm cortex, anterior olfactory nucleus, amygdala, and caudate putamen were atrophy-prone regions. Shrinkage of the neuronal somata and loss of large neurons with age are unique for SAM-P/10, both of which bring about age-related atrophy
Age-related changes in learning and memory skills of SAM-P/10 mice were investigated using a newly developed conditional avoidance retained the left-right turning discrimination in the T-maze and lost the ability to predict the forthcoming aversive shock by associating conditioned and unconditioned stimulus.
