Abstract :
ICA and eigen analysis were used in this paper to develop quantitative measures to underscore changes in hippocampal EEGs at subfields CA1 and the dentate gyrus during REM sleep as animal matures. Rats of 15 and 90 days old age were used to compare developmental changes. It was observed that the ratio of eigen values from 15-day old rats are much larger than those of 90-day old rats. There are no noticeable differences when comparing potential crosstalk effects at CA1 and the dentate gyrus. Statistical comparisons were performed between these two age groups.
