What is craniopagus twins? by Rachel

Craniopagus twins are a pair of twins joined together at the head. Craniopagus twin is a rare malformation found once in 2.5 million births (Squair, 2012). Many of the craniopagus twins are either stillborn or die within the first day from organ dysfunction. Only about one-fourth of craniopagus twins born will survive and be considered for surgical separation. 

According to research done by Squair (2012), craniopagus twins are mainly categorized into two: partial and total craniopagus. Partial craniopagus is less dangerous and has a higher chance of surviving a surgical separation than total craniopagus. In partial craniopagus, the union between the twins are limited. The twins have two brains and two crania, but the cranium could be fused. However, for total craniopagus, there exist two brains in one cranium. Cerebral development and blood circulation will be affected in twins who suffer from total craniopagus. 

Although craniopagus twins share their brains, each twin is a person. In many cases, each twin has different personalities and interests (Todorov et al., 1974).

Is intelligence related to schizophrenic? by Wong

In recent years, some studies have shown that the lowest of intelligence, the highest risk of schizophrenia. According to Virginia Commonwealth University's Dr. Kenneth S. Kendler, if you are brilliant, your schizophrenia genes do not have much chance of acting.

 

The amount we deviate from the predicted IQ that researchers get from our relatives is what really predicts our risk for schizophrenia. If we are a lot lower, we are at a higher risk of developing schizophrenia. Not having the IQ we should have based on our genetic makeup and family history appears to be the strongest predictor of schizophrenia.

 

He goes on to say that environmental factors that lower intelligence, such as early drug use or childhood trauma, may influence the high risk of schizophrenia associated with low IQ.

Can we live without corpus callosum? by Law

 

Yes. The corpus callosum does not have to be present in order for people to live. Such children and adults, on the other hand, are likely to lag behind their peers in terms of growth. They may be deaf or blind, and they may never learn to walk or speak. Many persons with corpus callosum agenesis live healthy lives. It can, however, cause medical issues such as seizures, which necessitate medical attention.

 

Does the brain can still function even when half of the brain has been removed? by Lilian

This occurrence could happen because of the brain's plasticity, allowing the brain to take over the other side of the brain's function to perform its task. This can be accomplished after a period of time recovery and extensive therapy program.
