The season we’re born in can have far-reaching consequences. For instance, Spring babies are more likely than others to develop schizophrenia later in life, whereas Summer babies tend to grow up to be more sensation seeking. There are many more of these so-called season of birth effects. Scientists aren’t sure, but they think such patterns could be due (among other things) to mothers’ and infants’ exposure to viruses over the Winter period, or to the amount of daylight they’re exposed to, either or both of which could influence genetic expression during early development. Now Spiro Pantazatos, a neuroscientist at Columbia University Medical Center, has studied links between season of birth and brain structure in healthy adults. He thinks the association between season of birth and psychiatric and behavioural outcomes later in life could be mediated by genetic factors that affect the growth of the brain.
