Brain size may depend upon how neural cells are cleaved

... the effects in vitro. Those studies revealed that impairing Gβγ did result in overproduction of neurons as a result of both daughter cells adopting the neuronal fate. Thus, the researchers concluded that Gβγ does control the orientation of cleavage and the identity of the daughter cells -- whether they will b...
