Women suffer depression and anxiety disorders at higher rates than men; a new study finds an interesting new explanation for this. Unwholesome family life can alter development of threat-detection circuits in the brain of young girls, which persist into adulthood and predispose women to developing mood and anxiety disorders as adolescents and young adults. Boys are also negatively impacted by family stresses during childhood, but the lasting effects on their brain were seen in only one of two neural circuits controlling our response to threats, anxiety and fear.
Heavier than I expected.
I feel like the answer should be that it was profound the first time. Enlightening. Humbling. But I just remember thinking how heavy it was.
The existential uppercut came later.
As the government shutdown nears the two week mark, it’s worth examining the effect of this latest political showdown on American science, and what this says about our collective values. This value conversation is relevant on the heels of Nobel prize winning scientists being placed on furlough while the congressional gym remains open. Continue reading
“Listen to your conscience,” my mother would say.But where does that mysterious urge to do what is right come from? Scientists have now pinpointed the brain circuitry that compels us to behave according to social norms; moreover, researchers can boost a person’s fairness by exciting this brain region, and promote cheating by inhibiting this bit of brain tissue.
The brain is a beautiful thing. It’s maybe not what most people think of as beautiful – I don’t think many people gaze into the gyri and canadian pharmacy online sulci of the brain and imagine a world in which they grab onto the temporal lobe and go lobe-in-hand into the moonlight. But it has a certain quality about it that inspires awe in the natural world. It is aesthetically pleasing and it “delights the senses” and so it fits the definition of most online (and print) dictionaries. Continue reading
Now in it’s the third year, the Dana Foundation is once again calling on the future neuroscientists of America to submit their most creative brain experiment ideas to the “Design a Brain Experiment Competition.” Last year the number of submissions tripled and we received some great experiment ideas, topped off by the winning submission, “The Use of Acetylcholinesterase Inhibitors in the Treatment of Schizophrenia,” from Charltien Long of the Head-Royce School in Oakland, California.

In any major mapping expedition shouldn’t the first priority be to survey the uncharted regions? In mapping the brain, that would be charting the neglected half–glia.
The Brain Mapping Initiative announced by President Barack Obama earlier this year seeks to map and monitor the function of neural connections in the entire brain of experimental animals, and eventually in the human cerebral cortex. Several researchers have raised doubts about the project, cautioning that mapping the brain is a far more complex endeavor than mapping the human genome, and its usefulness more uncertain.
