Paper Summary:

The paper relates that there are many studies into the long-term effects of heavy alcohol use and notes that it may lead to shrinkage of brain material. This in turn may lead to short-term memory deficits. The paper also relates that it is known that heavy alcohol use impairs the hippocampus which affects memory.

Outline:
Introduction
Brain Shrinkage and Short Term Memory Loss
Hippocampus Activity and Memory Loss
Conclusion

From the Paper:

"As discussed earlier in the essay, heavy consumption has been associated for some time that with reductions in the numbers of cholinergic neurons in the forebrain. The forebrain cholinergic neurons are distinguished into two groups, those of the basal ganglia and those of the basal forebrain. The cholinergic neurons of the basal forebrain project to the cortical regions, and the most rostral of these project to the allocortical regions such as the hippocampus. Therefore reductions in numbers of these cholinergic neurons will lead to reductions in activity of these allocortical regions, including the hippocampus. It is also possible that alterations in modulatory transmitter inputs such as cholinergic innervations may also play a role in the reduction of hippocampus activity without the actual loss of cholinergic neurons themselves. However in tests which have been performed on rhesus monkey models it has been shown that hippocampal activity reduction which is related solely to these alterations in modulatory input and not reductions in numbers of cholinergic neurons are unrelated to observed changes in memory function of any kind (Calhoun 475). This does not mean however that the reduction in hippocampal activity related to actual loss of cholinergic neurons does not lead to degeneration of memory function."
