Welcome to The Visible Embryo, a comprehensive educational resource on human development from conception to birth.

The Visible Embryo provides visual references for changes in fetal development throughout pregnancy and can be navigated via fetal development or maternal changes.

The National Institutes of Child Health and Human Development awarded Phase I and Phase II Small Business Innovative Research Grants to develop The Visible Embryo. Initally designed to evaluate the internet as a teaching tool for first year medical students, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than ' million visitors each month.


WHO International Clinical Trials Registry Platform
The World Health Organization (WHO) has created a new Web site to help researchers, doctors and patients obtain reliable information on high-quality clinical trials. Now you can go to one website and search all registers to identify clinical trial research underway around the world!

Graph showing relationship between age and mirror activity for a
normal brain and one with autism.
Developmental abnormalities in the mirror neuron system may contribute to social deficits in autism.

The mirror neuron system is a brain circuit that enables us to better understand and anticipate the actions of others. These circuits activate in similar ways when we perform actions or watch other people perform the same actions.

Now, a new study published in Biological Psychiatry reports that the mirror system in individuals with autism is not actually broken, but simply delayed.

Dr. Christian Keysers, lead author on the project, detailed their findings, "While most of us have their strongest mirror activity while they are young, autistic individuals seem to have a weak mirror system in their youth, but their mirror activity increases with age, is normal by about age 30 and unusually high thereafter."

This increase in function of mirror neuron systems may be related to increased capacity for social function or responsiveness to rehabilitative treatments among individuals with autism.

"The finding of late developing circuit functions could be very important. One wonders whether the recent breakthroughs in the genetics of autism could help to identify causes for the developmental delays. This type of bridge might help to identify novel treatment mechanisms for autism," said Dr. John Krystal, Editor of Biological Psychiatry.

One of the next steps in this line of research will be for researchers to examine how individuals with autism accomplish this improvement over time, and how therapeutic interventions targeting the same mechanism can help to support this important process.
