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!

In childhood, rituals like regular schedules for meal, bath, and bed times are a healthy part of behavioral development. But combined with oral and tactile sensitivities, such as discomfort at the dentist or irritation caused by specific fabrics, these rituals could be an early warning sign of adult Obsessive Compulsive Disorder (OCD).

According to Prof. Reuven Dar of Tel Aviv University's Department of Psychology, hypersensitivity and excessive adherence to childhood rituals may foreshadow the onset of OCD as the child ages.

He first suspected the link while working with OCD patients who reported sensitivity to touch and taste as children. Now, in the first comprehensive study of its kind, Prof. Dar and his fellow researchers have established a direct correlation between sensory processing — the way the nervous system manages incoming sensory information — and ritualistic and obsessive-compulsive behaviors.

The study, which appears in the Journal of Behavior Therapy and Experimental Psychiatry, suggests that when children experience heightened levels of sensitivity, they develop ritualistic behaviors to better cope with their environment. In the long term, this is one potential pathway to OCD.

Connecting the Behavioral Dots

Two studies were devised to map the connection between sensory processing, rituals, and OCD.

In the first, parents of kindergarten children were asked to complete three questionnaires on their child's behaviour — their level of ritualism, such as the need to repeat certain acts or to order objects in a particular way; their level of anxiety, with questions relating to reaction to strangers, worrying about outcomes of events, and attachment to family members; and last, their reactions to everyday sensory events such as being touched or exposed to unusual tastes or smells.

In the second study, the researchers asked 314 adult participants to answer surveys online in relation to their OCD tendencies, their anxiety levels, and their past and current sensitivity to oral and tactile stimulation.

Results from both studies indicated a strong connection between compulsive tendencies and hypersensitivity.

In children, hypersensitivity was an indicator of ritualism, whereas in adults it was related to OCD symptoms. As a whole, these findings provide preliminary support for the idea that such sensitivities are a precursor to OCD symptoms.

When children are extremely sensitive to certain types of touch or smell, they can feel that they are being attacked, or that the environment is threatening them, Prof. Dar believes. Ritualism could develop as a defence mechanism, helping these children to regain a sense of control, which is also a symptom of adults with OCD.

Identifying the Turning Point

Next Prof. Dar hopes to conduct a longitudinal study to better understand the connection between hypersensitivity in childhood and adult OCD, following a large sample of children who experience oral and tactile sensitivities through to adulthood.

Of course, Prof. Dar says, all children have particular habits and preferences, and they're not all precursors to OCD.

So what should parents watch for to correctly characterize normal and potentially pathological behavior?

"If you see that a child is very rigid with rituals, becoming anxious if unable to engage in this behavior, it is more alarming," he explains. Also, age is a factor. A habit exhibited by a five- or six-year-old is not necessarily a predictor of OCD.

If the same behavior continues to the ages of eight and above, it could be a warning sign, especially if accompanied by anxiety or distress.
