Ruth Buczynski, PhD interviews Louis Cozolino, PhD about how the neuroscience of human brains interact with one another. Neuroscience is giving us insight into how our brains really work and provides us with practical information for our daily lives and interactions with others.

Humans show consistent differences in the extent to which their behavior reflects a bias toward appetitive approach-related behavior or avoidance of aversive stimuli [Elliot, A. J. Approach and avoidance motivation. In A. J. Elliot (Ed.), Handbook of approach and avoidance motivation (pp. 3-14). New York: Psychology Press, 2008]. We examined the hypothesis that in healthy participants this motivational bias (assessed by self-report and by a probabilistic learning task that allows direct comparison of the relative sensitivity to reward and punishment) reflects lateralization of dopamine signaling. Using [F-18]fallypride to measure D2/D3 binding, we found that self-reported motivational bias was predicted by the asymmetry of frontal D2 binding. Similarly, striatal and frontal asymmetries in D2 dopamine receptor binding, rather than absolute binding levels, predicted individual differences in learning from reward versus punishment. These results suggest that normal variation in asymmetry of dopamine signaling may, in part, underlie human personality and cognition.
Home is more than a place on a map. It evokes a particular set of feelings, and a sense of safety and belonging. Location, memories,… (How #neuroscience can explain why "home is where the heart is". Why does 'home' feel special?
The minds of men and women are 99% the same, but that 1% may make all the difference. Studies of that 1%, for instance, have found that a female’s frontal lobe, responsible for problem-solving, is larger than in a man.

People shouldn’t assume that someone who can easily read their feelings always has their best interests at heart.
Although good emotion-recognition skills might seem like concern and empathy, some people might use these skills to manipulate others, new University of Michigan research suggests.
Both manipulative and empathetic people are equally capable of reading others’ emotions, according to U-M researchers, who conducted two studies examining the relationship between narcissism, empathy and emotion recognition.
In this upcoming season, when our families will gather and we're reminded how much our relationships matter, have we taken the time to think about, and thank, those who have helped us along the way in our business?
