Measuring head circumference (also known as occipito-frontal circumference) is a significant part of the proper evaluation of a child’s growth and development, as it represents a direct indication of head growth. Therefore deviations from normal head growth may reveal certain congenital or acquired problem.

New molecular insight into vertebrate brain development

In the December 1st issue of G&D, Dr. Fred H. Gage (The Salk Institute for Biological Studies) and colleagues reveal a role for the Hippo signaling pathway in the regulation of vertebrate neural development, identifying new factors - and potential therapeutic targets - that may be involved in congenital brain size disorders and neurological tumor formation.

Eye blinks may help to identify children prenatally exposed to alcohol

While children with fetal alcohol syndrome (FAS) have identifiable craniofacial abnormalities, children with alcohol-related neurodevelopmental disorder (ARND) can have significant cognitive impairments without facial anomalies. An important new study has found that a deficit in eyeblink conditioning (EBC) can identify children with probable FAS, and may also serve to identify alcohol-exposed children who lack distinctive FAS features.

Evolutionary connection between food supply and brain size

In a study of orangutans living on the Indonesian islands of Borneo and Sumatra, scientists from Duke University and the University of Zurich have found what they say is the first demonstration in primates of an evolutionary connection between available food supplies and brain size.

Acne drug which causes birth defects too hard to monitor

According to the birth watchdog group the March of Dimes, preventing birth defects from a widely used acne drug is too heavy a burden on doctors, patients and pharmacists.

Novel way in which the brain size of developing mammals may be regulated

Howard Hughes Medical Institute researchers have discovered a novel way in which the brain size of developing mammals may be regulated. They have identified a signaling pathway that controls the orientation in which dividing neural progenitor cells are cleaved during development.

Evolution has been working very hard to produce us humans

The genes that regulate brain development and function evolved much more rapidly in humans than in nonhuman primates and other mammals because of natural selection processes unique to the human lineage. Researchers reported their findings in the cover article of the Dec. 29, 2004, issue of the journal Cell.
