Directing neuronal traffic

How a gene controls neuronal traffic in the assembly of an electrical circuit. To form the complex circuits of the brain, neurons have to know when to grow and when to stop. The above image displays light-sensing neurons in the eye of a fruit fly (red and green)....

The nervous system of the fruit fly, magnified 40 times. There was a time when we thought genes controlled everything and that humans were genetically superior. Yet the human genome is estimated to have only 23,000 protein-encoding genes, while the minuscule fruit fly...

Finally these concepts are starting to hit mainstream media: that your genes do not control your future, and are not to blame for all your problems. In the nature/nurture argument, genetic manifestation of what’s going on in your life accounts for less than 25%....
