In this sense, it may be “normal” for an 8-year-old girl to have an attention span of 12 minutes, for instance, whereas a boy of the same age might also be considered normal with a span of only 9 minutes. Older students typically continue to develop longer attention spans as they ...

The purpose of this study was to determine whether reproducible normative values for hand dexterity and grip and pinch strength could be obtained in young children using simple tests that could be administered quickly within the attention span of a 3- to 5-year-old. The Functional Dexterity Test...
Minute-by-minute res- piratory variability, as measured by the interquartile range, is shown in Figure 3. Periodic modulation throughout the 12-hr records was again pronounced. Respiratory rate and variability decreased across the agespan studied. Respiratory rate and variability were greatest when...

There is a growing literature on the impact of ethnicity on brain structure and function. Despite the regional heterogeneity in age-related changes and non-uniformity across brain morphometry measurements in the aging process, paucity of studies investig

and dendrites is also supported by the evidence that overall brain metabolism, which derives largely from resting neuronal membrane potentials (Mata et al, 1980; Nudo and Masterton, 1986), begins to decline at ages 9–10 years to reach adult levels by age 16–18 years (Chugani, 1994; Chugan...
