Although it remains unclear why higher age is associated with higher (I ST, several factors of morphological brain maturation related to age are hypothesized to influence ST [ 33].
Morphological characteristics and age were considered to verify the developmental stages.
All litters were documented, and pup age was estimated based on morphological development.
Gestational age was confirmed using external morphological features at necropsy (Theiler 1989).
Correlations of morphological and gene expression phenotypes as a function of age were determined by regression analysis.
As aging is associated with degenerative morphological changes in the central nervous system, we examined brain sections from 50 day old per, CSp, and per { per +} males.
The identification and quantification of morphological alterations that occur in the brain due to neurological disease, development and ageing, is of special interest in brain research.
Aging is known to occur in bacteria and yeast that divide with morphological asymmetry [1] [3].
The development of molecular methods for age estimation allowing to use human specimens that possess no morphological age information, such as bloodstains, is extremely valuable as this type of samples is commonly found at crime scenes.
Behavioral, morphological or neurophysiological correlates of aging are extensively studied in diverse organisms, ranging from caenortabitidis (C. elegans) to non-human primates [3], [4].
