Document Summary
Psc 101 lecture 8 reproductive behavior. In brain activity studies, older subjects show less cortical activation during memory retrieval. Loss of neurons or neuronal connections may explain impairment. Aged rats that perform poorly on tests also have reduced ach activity. This decline is only seen when aging is associated with impaired performance not solely with age. The septal complex provides input to the hippocampus. Many of the neurons use acetylcholine (ach) as their transmitter. This pathway seems to be involved in memory decline. Pursuing occupations involving high complexity and low routine. Being involved in activities that are complex or intellectually stimulating (reading or travelling) Having a spouse with high cognitive status .
