Comments: The adult brain is more plastic than was realized. This can be a double edged sword.

(PhysOrg.com) -- In a paper published in Proceedings of National Academy of Sciences, Veronica Kwok, Li-Hai Tan, and their colleagues at the University of Hong Kong, conclude that the adult human brain is capable of new rapid growth when exposed to stimuli similar to what babies experience as they are learning from their environment.

HIGH SODIUM, LOW STRESS?
All those salty snacks available at the local tavern might be doing more than increasing your thirst: They could also play a role in suppressing social anxiety.

New research from the University of Cincinnati (UC) shows that elevated levels of sodium blunt the body’s natural responses to stress by inhibiting stress hormones that would otherwise be activated in stressful situations. These hormones are located along the hypothalamic-pituitary-adrenal (HPA) axis, which controls reactions to stress.

COMMENTS: We put food addiction studies up because food addiction closely parallels porn addiction, in that both are are natural reinforcers. A natural reinforcer is what your reward circuit evolved to respond to. Food and sex are the 2 primary missions of your reward circuitry and dopamine (along with bonding).
As a physiology teacher this one stumps me. It's probably some epigenetic change, but how? How could it be high blood sugar or blood fat affecting the fetus? Both are kept within certain ranges in the blood. And both could be raised by normal high fat/high glucose foods.

Youth at risk for obesity show greater greater reward circuitry activity in response to food

COMMENTS: We talk about a numbed pleasure response, which is mainly due to lower levels of dopamine (D2) receptors. Studies show that overeating on sugary/fat food causes a decline in D2 receptors (humans and rats). This study shows that lean adolescents, at risk for ending up fat, get a bigger buzz of dopamine from food than their counterparts. In addiction terms, this is called sensitization. A bigger buzz leads to overconsumption, which leads to desensitization (numbed pleasure response), and further overconsumption because it is less satisfying.
