Possible link between autism and antidepressants use during pregnancy: Mouse Study
A new study in mice reveals a possible link between the use of SSRI antidepressants during pregnancy and an increased risk of autism-like symptoms in offspring. Offspring exposed to fluoxetine (Prozac) in utero were more likely to exhibit impaired neurotransmission caused by an overactive serotonin receptor in the prefrontal cortex, an area of the brain implicated in modulating social behaviors. However, treating the mice with a compound that blocks the receptor alleviated the behavioral problems and improved working memory.... Read More...
Brain scans on movie watchers reveal how we judge people
Using a combination of movie clips and neuroimaging, researchers find people have positive biases to those they feel are more like them, even if they are unable to see the person's face.... Read More...
How education may stave off cognitive decline
Neuroimaging reveals those who have spent more years studying have increased cortical thickness in the medial prefrontal cortex, anterior cingulate and orbitofrontal areas of the brain. Researchers also identified enhanced gene expression profiles in these brain regions that promote information processing and provide protection against some age-related neurodegenerative diseases....
