Researchers from the University of Alabama at Birmingham (AL, US) presented a paper at Neuroscience 2010, the annual meeting of the Society for Neuroscience in which they reported that exposure to nicotine during pregnancy leads to a decrease in adult stem cells and a change in synaptic plasticity in the hippocampus of the offspring. The synaptic changes could have lifelong consequences for the offspring. According to Professor Robin Lester of the Department of Neurobiology and lead researcher on the project, “These problems could include various cognitive deficits, learning difficulties, [and] ADHD.”
These are very preliminary findings. They come from research conducted with rats and will require extensive additional work to make the connections to human learning. Note that the mother rats apparently were also ingesting nicotine while nursing (first 10 days after birth) as well as during pregnancy. My reporting here is based entirely on press releases from UAB and the Society for Neuroscience (with abstract).
