Figure 2From: Spatial memory decline after masticatory deprivation and aging is associated with altered laminar distribution of CA1 astrocytesLaminar distribution and graphic representations of quantitative data of astrocytes in the CA1 hippocampal field. (A): Photomicrographs of CA1 layers in hippocampal sections from 3-, 6- and 18-month-old SD and HD mice. These sections were representative of mice that had astrocyte levels that were close to the mean values for each group. (B): The mean number and standard errors (s.e.m.) of stereological estimates of the total number of astrocytes for each CA1 layer in mice of the indicated age. (*) = Statistically significant differences (two tailed t-test; p < 0.05) between HD and SD age-matched mice. (#) = Statistically significant differences between SD and HD mice of different ages. LacMol. = stratum lacunosum-moleculare; Rad = stratum radiatum; Py = stratum pyramidale; Or = stratum oriens; HD = hard diet; SD = soft diet; 3 M, 6 M and 18 M indicate 3-month-old, 6-month-old and 18-month-old mice, respectively.
