Document Summary
Fraternal twins alexis and noah beery had cerebral palsy. Symptoms usually don"t get worse but it did for them. After reading an article and analyzing their blood, doctors and fam found that the twins had an abnormality in a gene for an enzyme that enhances the production of dopamine and serotonin. They were given medication that would turn into serotonin and dopamine and then the twin greatly improved. This was the first diagnosis established through genome sequencing that has led to a treatment success. Understanding genes, proteins, and cellular function allows us to understand normal brain functioning as well. Brain cells give the nervous system and its many parts their structure: also mediates its moment-to-moment changes underlies our behaviour. Jean livet and his colleagues at harvard developed a transgenic technique that labels many diff neurons by highlighting them with distinct colours .
