D are more similar to the personalities of their caregiving adoptive parents than to the personalities of their biological parents. The results suggest that the working memory system contributes strongly to learning impairments in schizophrenia and also highlight the brain area responsible for the dysfunction, which is the prefrontal cortex.

Which part of your brain is essential for receiving information that you are moving your legs? The occurrence of antisocial behavior is not exclusively during the course of Schizophrenia or a Manic Episode. A separate form not included in this scheme, incentive salience, primarily addresses dopamine function in addiction and refers only to approach behavior as opposed to learning.

This finding is congruent with the observation that pharmacological inhibition of the infralimbic cortex attenuates depressive behaviors. Neurotransmitters are best described as A electrically charged atoms. Random sampling minimizes between a sample and a population. Because the reward pathway—and many of the genes that underlie it—functions in much the same way in mice as it does in people, mice are leading the way in identifying addiction genes. Pathological changes in brain function that result from substance abuse cause the skewed decision making common to addicts. Is based on naturalistic observation B.

This antidepressant drug functions as a n A steroid. Thus, though the altered addict brain often acts irrationally, it may be more accurate to describe those behaviors as pre-rational. B understanding what others are saying. About 85 percent of human brain weight comes from the A hippocampus. This sensitization in the brain is similar to the effect of dopamine because wanting and liking reactions occur.

B enhance moral reasoning skills. C a single egg cell by two sperm cells. Ding also found that aldehyde dehydrogenases are expressed not only in the liver, where most of the alcohol we drink gets metabolized, but in some parts of the brain that, to Ding -- whose professional career has focused on the brain's dopamine-producing nerve circuitry -- looked anatomically identical to the dopamine-producing nerve cells that feed the reward circuit. Jeremy's reaction best illustrates the nature of A the pain reflex. A tendency for the brain's left and right hemispheres to serve different functions is called A hemispherectomy.

In the United States, excessive behavior patterns—involving smartphone use, Internet gambling, gaming, , even eating and shopping—are under study as a behavioral addiction. The Science of Addiction There are plenty of myths and misconceptions about addiction, but in reality, the processes that give rise to addictive behavior resist a simplistic explanation.
