Neuroscientists Suggest That Social Inequalities Can Permanently Alter Our Brains
A recently published article illustrates how the concept of neuroplasticity has been used to explain social inequalities, like poverty, by linking them to biomarkers in the brain.
When is Stress Good for You?
In this piece for Aeon, Bruce McEwen discusses how "good stress," "tolerable stress," and "toxic stress" act epigenetically on our brain structure, and how we can...
“Can You Think Yourself into a Different Person?”
Will Storr, for Mosaic Science, wades into the world of neuroplasticity and explores to what extent our brains are capable of changing through adulthood. He asks if the tendency to overemphasize the findings of epigenetics and neuroplasticity isn’t tied to our cultural belief that individuals are totally free to create themselves and pursue the American dream.
“Nature and Nurture: Human Brains Evolved to be More Responsive to...
"We found that the anatomy of the chimpanzee brain is more strongly controlled by genes than that of human brains, suggesting that the human brain is extensively shaped by its environment no matter its genetics," said Aida Gómez-Robles, postdoctoral scientist at the GW Center for the Advanced Study of Human Paleobiology and lead author on the paper. "So while genetics determined human and chimpanzee brain size, it isn't as much of a factor for human cerebral organization as it is for chimpanzees."
A Story About NMDA Receptor Subunits, and Why SSRIs Impair Cognitive...
The impact of long-term SSRIs on memory-related nerve cell receptors does have functional consequences. Research shows that SSRIs impair the acquisition of fear memories. (Perhaps a positive outcome.) But unlearning fear memories involves new learning as well, and according to a study by LeDoux and colleagues, long-term exposure to SSRIs makes it harder to unlearn fear memories.
