Amino Acid May Help Reduce Cocaine Cravings
A new study in rats has found that N-acetylcysteine (NAC), a commonly available and generally nontoxic amino acid derivative, reverses changes in the brain's circuitry associated with cocaine addiction. The reversal appears to lessen the cravings associated with cocaine, thus providing protection against relapse.

Brain Emotion Circuit Sparks As Teen Girls Size Up Peers
What is going on in teenagers' brains as their drive for peer approval begins to eclipse their family affiliations? Brain scans of teens sizing each other up reveal an emotion circuit activating more in girls as they grow older, but not in boys. The study shows how emotion circuitry diverges in the male and female brain during a developmental stage in which girls are at increased risk for develop

Drug-Free Flipping Of The Brain’s Addiction Switch
When someone becomes dependent on drugs or alcohol, the brain's pleasure center gets hijacked, disrupting the normal functioning of its reward circuitry. Researchers investigating this addiction "switch" have now implicated a naturally occurring protein, a dose of which allowed them to get rats hooked with no drugs at all. The research will be published Friday in the journal Science.

Past Experience Shown To Be Invaluable For Complex Decision Making
Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have shown that past experience really does help when we have to make complex decisions based on uncertain or confusing information. They show that learning from experience actually changes the circuitry in our brains so that we can quickly categorise what we are seeing and make a decision or carry out approp

Past Experience Is Invaluable For Complex Decision Making, Brain Research Shows
Researchers have shown that past experience really does help when we have to make complex decisions based on uncertain or confusing information. They show that learning from experience actually changes the circuitry in our brains so that we can quickly categorize what we are seeing and make a decision or carry out appropriate actions.
