Sentences with phrase «increased reward sensitivity»

The externalizing pathway highlights the underlying neurological systems of increased reward sensitivity and reactivity combined with decreased effortful control and regulation that are imbalanced and competing during adolescence (i.e., dual systems model), which further contributes to adolescence being a high - risk period for the onset of substance use and comorbid behavior problems [80, 81].

This inquiry is also important, since research suggests that adolescents with disruptive behaviors exhibit increased reward sensitivity (Byrd et al., 2014), and pictures of happy faces have been shown to activate reward - related brain networks (Morris et al., 1996; Phillips et al., 1998; Whalen et al., 1998).

Nevertheless, greater attention orientation toward happy faces, for children with high CU traits and high ODD - related problems, is in line with data suggesting that adolescent youth with disruptive behaviors exhibit increased reward sensitivity (Byrd et al., 2014) and that CU traits are associated with a tendency to be over-focused on reward (Frick et al., 2003; Frick and White, 2008).

Not exact matches

The researchers also found increased activity between areas of the prefrontal cortex and the nucleus accumbens, a center for reward sensitivity that is often implicated in addiction research.

So both increased and decreased reward sensitivity could lead to obesity?

Marijuana abusers showed lower scores on positive emotionality and higher scores on negative emotionality than controls, consistent, on the one hand, with lower reward sensitivity and motivation and, on the other hand, with increased stress reactivity and irritability.

Positive emotionality was inversely associated with MP - induced increases in midbrain DA, which could reflect the fact that in midbrain, D2 and D3 are autoreceptors; therefore, their stimulation would result in decreased DA release in striatum (including accumbens)(74), leading to decreased sensitivity to reward and amotivation (75).

CBD can stimulate the appetite by increasing sensitivity to the smell and taste of food in dogs, making eating a more rewarding experience for your pooch.
