More than 20,000 autopsy reports from several general hospitals were surveyed for the purpose of selecting brains without a pathological lesion that had been weighed in the fresh condition. From this number, 2,773 males and 1,963 females were chosen for whom body weight, body height, and cause of death had been recorded. The data were segregated into 23 age groups ranging from birth to 86+ years and subjected to statistical evaluation. 
Brain weights in adult africansa

The brain weight of adult Africans in the study is similar to that seen in Caucasians, and there is no statistically significant difference in the brain weight from early adulthood to the elderly adults.
The aging human brain
In the absence of superimposed disease (which frequently limits aging studies), overall functions can be maintained at high and effective levels because of the plasticity and redundancy capabilities of the human brain.
Brain weight throughout the life span of the chimpanzee
It is suggested that brain weight declines moderately with age in the chimpanzee as it does in humans.
Intelligence and brain size in 100 postmortem brains: sex, lateralization and age factors.
It was found that cerebral volume decreased only minimally with age in women, leaving the basis of the well-documented sex difference in cerebral volume unaccounted for, and point to the need for responsibility in the consideration of the possible use of brain images as intelligence tests.
Lifespan changes in the index of cephalization.
In both species brain and body weights are greater in males than in females, but when the data are translated into the several brain-body parameters females generally show higher indices than males, and this correlates with their superior longevity.
Normal internal organ weight of Thai adults correlated to body length and body weight.
Analysis of data from 250 autopsies from the Ramathibodi Hospital from August 2003 to February 2005 showed each internal organ significantly correlated with body weight in males at p-value < 0.05, whereas in females it only correlated to liver, kidney and spleen.
Correlation of internal organ weight with body weight and length in normal Thai adults.
Relationship was found between internal organs weight and body weight andBody length of males whereas, in females the weight of internal organs except the kidneys was not related to body length.
Brain weight in completed suicide and other cases of death–comparison of recent and previous studies
The brain weight depends on various parameters such as gender, age, body height, and weight, and the selection criteria for suicide cases as well as for the corresponding control population are essential in evaluating the brain weight in suicide.
Correlation of neuronal cell body size in motor cortex and hippocampus with body height, body weight, and axonal length.
The findings indicate that: 1) body height has a greater effect than body weight on the motor neuron cell size, probably because of its association with axonal length; 2) the effect is regional (motor cortex) rather than general.

In a review of nearly 1,100 autopsies on African children from birth to 15 years of age, an analysis was made of body weight and spleen, liver, heart and brain weights. The results were grouped by
XX. Contributions towards determining the weight of the brain in different races of man
The Brain being the most essential and characteristic portion of the human organization, as connected with intelligence and mental manifestations, it would naturally be expected to have absorbed
Body Length and Organ Weights of Infants and Children: A Study of the Body Length and Normal Weights of the More Important Vital Organs of the Body between Birth and Twelve Years of Age.
Owing to the meager data regarding weights of normal organs of infants and children, it seemed advisable to make use of records for this purpose, and the substance of this study is based.
Standards from birth to maturity for height, weight, height velocity, and weight velocity: British children, 1965. II.
The solution to the alternatives of plotting against chronological or developmental age at adolescence is adopted and centiles plotted against chronological age over the whole age span are given.
The determination of a single standard figure of weight for each unit of height, age and sex is somewhat uncertain and on the whole unsatisfactory, since (contrary to common opinion) there are usually more overweight than underweight children and average or mean weights of a given series are probably too high.
