What is Fetal Alcohol Syndrome (FAS)?Fetal Alcohol Syndrome: •Specific set of alcohol-induced defects in children born to mothers who heavily abused alcohol when pregnant •Pre- and Post-natal Growth Deficiencies •Minor Facial Abnormalities •Central Nervous System Defects•Severity of defects depends on: •Developmental stage when exposed •Vulnerable cellular populations and mechanisms •Severity, duration, and frequency of exposure
FAS and the Embryo Project Encyclopedia (EPE):EPE examines “agents of change shaping embryo research and its multiple contexts” •Peer-reviewed, online encyclopedia •Articles written primarily for lay audienceMethods for examining FAS with the EPE: •13 FAS-related articles written •Articles examine specific developmental defects and socio-historical context •Developmental timeline of alcohol’s effects created to represent this cluster
