Length of Pregnancy Influenced by Placenta Structure

Some humans  placentas do not form the complex structure seen in animals

The nine-month pregnancy in humans is influenced by the structure of the placenta, according to new research into the evolution of reproduction in mammals which ends a 100-year mystery.

Baby Brain Growth Mirrors Changes from Apes to Humans

100712154422-large

Areas of expansion in the human cortex during infancy and childhood, top, closely match areas of change in the human brain when compared to the brains of apes and monkeys. Yellow areas expanded the most, followed by orange, red, blue and light blue areas.

A study undertaken to help scientists concerned with abnormal brain development in premature babies has serendipitously revealed evolution’s imprint on the human brain.

Even premature babies at 33 weeks post-conceptional age, about 2 months before term (40 gestational weeks), are capable of recognizing and distinguishing two objects of different shapes (a prism and a cylinder) with their right or left hands. This is the first demonstration of fully efficient manual perception in preterm human infants.

The brains of infants who die of sudden infant death syndrome (SIDS) produce low levels of serotonin, a brain chemical that conveys messages between cells and plays a vital role in regulating breathing, heart rate, and sleep, reported researchers funded by the National Institutes of Health.

Why Does a Human Baby Need a Full Year Before Starting to Walk?

Why does a human baby need a full year before it can start walking, while a newborn foal gets up on its legs almost directly after birth?

Why does a human baby need a full year before it can start walking, while a newborn foal gets up on its legs almost directly after birth? Scientist have assumed that human motor development is unique because our brain is unusually complex and because it is particularly challenging to walk on two legs. But now a research group at Lund University in Sweden has shown that human babies in fact start walking at the same stage in brain development as most other walking mammals, from small rodents to elephants.

Wireless Phones Can Affect The Brain, Swedish Study Suggests

Mobile phones and other cordless telephones have a biological effect on the brain, according to new research.

A study at Örebro University in Sweden indicates that mobile phones and other cordless telephones have a biological effect on the brain. It is still too early to say if any health risks are involved, but medical researcher Fredrik Söderqvist recommends caution in the use of these phones, above all among children and adolescents. Few children who regularly use mobile phones use a headset often or always, even though the Swedish Radiation Safety Authority recommends this.

A new study finds high rates of childhood exposure to violence and abuse in United States.

A new study from the University of New Hampshire finds that U.S. children are routinely exposed to even more violence and abuse than has been previously recognized, with nearly half experiencing a physical assault in the study year.

New research sheds light on how alcohol alters the way brain cells work.

Alcohol’s inebriating effects are familiar to everyone. But the molecular details of alcohol’s impact on brain activity remain a mystery. A new study by researchers at the Salk Institute for Biological Studies brings us closer to understanding how alcohol alters the way brain cells work.
