A Systematic Review of the Role of Gummosin in Improving Memory in the Scopolamine Impaired Memory Model.

In this study, the role of gummosin in improving memory in the scopolamine memory impairment model was systematically examined. Memory and learning are the most developed and complex functions of the nervous system. Learning is the acquisition of new information that occurs as a change in behavior, and memory is the ability to store and retrieve learned information. In other words, memory is a combination of various processes of information acquisition, consolidation, storage and retrieval. The processes of memory consolidation and storage are the result of a series of time-dependent neurobiological events that occur after the initial formation of memory. In addition, this fluctuation of processes related to memory storage can fully occur shortly after the initial learning experience. Memory is a direct result of learning ,as it stores and retrieves learned experiences and information. The results of our study show that scopolamine leads to impaired memory, learning and synaptic plasticity, which is associated with a change in the expression of various genes and a reduction in the number of hippocampal neurons. The disorders that occurred in the rats of the scopolamine group confirm the model used in this study to induce memory and learning deficits, which is consistent with previous studies confirming the model used to induce Alzheimer's disease. The results of the behavioral tests in this study showed that, consistent with previous work, scopolamine caused a significant increase in anxiety behavior that was associated with a decrease in time spent in the central area compared to the control group, while donepezil injection resulted in a decrease in anxiety behavior. The time spent in the central area was increased compared to the scopolamine group.
