article_snippet: Dr Nadja Reissland, of Durham University,  said the ultrasound scans show unborn babies of mothers who smoke may have delayed development of unborn babies of mothers who smoke central nervous systems .

article_snippet: The pilot study, which Dr Reissland hopes to expand with a bigger sample, found babies carried by smoking mothers may have delayed development of the central nervous system.
article_snippet: Dr Reissland believed that videos of the difference in pre-birth development could help mothers give up smoking.
