Morphological Measurements in the Aging Rat Cerebral Cortex

  • Marian C. Diamond
  • James R. Connor


This chapter deals with the structural changes seen in the brains of aging rats exposed to differential environments. We have previously reviewed the overall progress of experiments from our laboratory indicating brain changes due to modified external stimuli (Diamond and Connor, 1981, 1982). We showed changes in occipital cortical cell number and pyramidal cell dendrites from animals living in enriched, standard colony, and impoverished conditions. The present chapter includes some of the same data, but adds new information from the somatosensory cortex which has more recently been obtained. New dendritic spine data have also been presented to compare with our previous work.
