Can Alcohol Dependence Be Reversed?
A specific group of brain cells appears to drive excessive alcohol drinking, and targeting these cells may reverses alcohol dependence, at least in rats, a new study finds.

In the study, the researchers trained rats how to self-administer alcohol out of a chamber, and caused some rats to become dependent on alcohol. They then injected the rats with a compound that could inactivate, or "turn off" a very specific set of brain cells in the amygdala.

They found that inactivating these brain cells caused the rats to completely cease their compulsive drinking.

New role found for the immune system: Controlling Social Interactions
In a startling discovery that raises fundamental questions about human behavior, researchers at the University of Virginia School of Medicine have determined that the immune system directly affects – and even controls – creatures’ social behavior, such as their desire to interact with others.

So could immune system problems contribute to an inability to have normal social interactions? The answer appears to be yes, and that finding could have significant implications for neurological diseases such as autism-spectrum disorders and schizophrenia.

“The brain and the adaptive immune system were thought to be isolated from each other, and any immune activity in the brain was perceived as sign of a pathology. And now, not only are we showing that they are closely interacting, but some of our behavior traits might have evolved because of our immune response to pathogens,” explained Jonathan Kipnis, chair of UVA’s Department of Neuroscience.

“It’s crazy, but maybe we are just multicellular battlefields for two ancient forces: pathogens and the immune system. Part of our personality may actually be dictated by the immune system.”

Oui oui oui oui oui oui !!!
In my experience, what we need is a calm mind and warm-heartedness provides a basis for that. That’s how we make ourselves happy as individuals in families, local communities and nations. I believe that if we can train those who are young today in these qualities the world will be a more peaceful place later in this century.
