Why Girls Are More Vulnerable to Maltreatment

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.

To Kill a Crying Baby

Squeezing her hand over the toddler’s nose and mouth she smothered him to death because he would not stop crying.  Last Monday 22-year-old Jessica Fraraccio pleaded guilty in court to felony murder of 23-month-old Elijah Nealey in the summer of 2012.  No one in their right mind could conceive of committing such a horrible act, but babies are tragically killed or left severely brain damaged by shaken baby syndrome inflicted by a parent, family member, or caretaker frustrated by a child’s incessant crying. Dismissing those with depraved minds, how can we comprehend such sad stories as this one in the Washington Post?

Neural Circuits of Fair Play Discovered in the Human Brain

“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 Beautiful Popping Brain

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

Design a Brain Experiment Competition Is Back!

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.

Patient Zero: What We Learned from H.M.

Memory is our most prized human treasure. It defines our sense of self, and our ability to navigate the world.  It defines our relationships with others – for good or ill – and is so important to survival that our gilled ancestors bear the secret of memory etched in their DNA. If you asked someone over 50 to name the things they most fear about getting older, losing one’s memory would be near the top of that list. There is so much worry over Alzheimer’s disease, the memory thief, that it is easy to forget that our modern understanding of memory is still quite young, less than one, very special lifespan.

Meet the Patient Zero of memory disorders, H.M.
