You connect neurons by steering the growth cones through chemical gradients. Using the genes that affect large number of neurons at once.

Directly effecting neural growth patterns isn't the only way for genes to effect human behavior. Consider for example, the effect on human behavior of drugs like caffeine, alcohol, anti-depressants, etc. Keep in mind any drug effect can be approximately stimulated by affecting any of the steps in the chemical cascade the drug uses.
