Recently a crew from BBC Horizon came to the lab I toil in as a graduate student to film this clip for a program they titled, “What Makes a Genius”.  They wanted to film a knockout mouse a postdoc in the lab created, and that I happen to be doing my thesis work on.  This mouse is missing a gene that is important for proper growth of neurons.  Some of my work, and others, has shown that it has trouble forming connections in its brain during development.  This is why we think it is not a great learner.  However, the way this clip explains the research, I’d want to give my boss, Elly, a Nobel Prize for finding THE intelligence gene.  So let’s go through this clip’s weak and strong points.
