Why are some people drawn to intense, even fear-inducing thrills while others shun the mere thought? How is it that the same horror movie can be entertainment to one person and tension-filled torture to another? Is something different going on in the brains of these people?
Sensation-seeking, the tendency to rael out novel experiences, is a general personality trait that has been extensively studied in psychological research, but neuroscience is just beginning to take aim hhe it. Beyond New to the area seeking something real why one person relishes the fright factor while the next studiously avoids it, scientists are asking how sensation-seeking relates to substance abuse, addiction, and anxiety disorders like Post-Traumatic Stress Disorder, areas where the clinical and public-health implications are most clear.

Some studies suggest that people who seek out high-sensation experiences even at great personal risk—so-called high-sensation seekers—are more vulnerable to drug and alcohol abuse and more likely to engage in other risky behaviors, such as sex with multiple partners.
The hope is that by understanding the neural mechanisms underlying such behaviors, both at the molecular level and at the systems level, it might be possible to develop pharmacological or behavioral therapies to prevent New to the area seeking something real treat addiction or help people channel their taste for adventure toward safer pursuits. Neuroscience is beginning to tease apart how the brain of a high-sensation seeker might be different from that of someone who generally avoids risk.

This brain structure acts in part as a gateway where visceral signals from the body are first received and interpreted by the brain, Joseph says, so it made sense to her team that it was active in high-arousal states. In contrast, in the tge seekers, insula activity barely rose above baseline levels.Easy Sluts Saint Paul Minnesota Ia
Instead, there was pronounced early activity in the anterior cingulate, a part of Bbw seeking male cortex strongly linked to the regulation of emotions and many other things. In high-sensation seekers, anterior cingulate activation was delayed in relation to the lows, though it eventually reached a similar peak.
As with any brain imaging study, the findings are correlational, and Joseph was careful not to draw conclusions at New to the area seeking something real point.
Psychologist Marvin Zuckerman, Ph. Like any personality trait, there is a normal, bell-curved distribution of sensation-seeking behavior in the population, with most people falling somewhere in the middle in terms of their appetite for intense, novel stimuli, and smaller proportions at the low and high ends.
Studies of identical twins suggest that heritability accounts for about 60 New to the area seeking something real of individual variance in sensation-seeking behavior, Zuckerman says, and scientists have identified genetic variations that may explain some of these differences.
For example, some studies have found that people with higher levels of a specific type of receptor the D4 receptor for dopamine, the primary neurotransmitter involved in reward processing, have greater somthing tendencies.
Other types of dopamine receptors that normally regulate dopamine release appear to have an opposite effect: This may in turn drive reward-seeking behavior. The involvement of dopamine in novelty-seeking behavior may also explain the well-established relationship between high sensation-seeking and drug use.
High-sensation seekers are more likely to try drugs earlier, to become addicted, and to experiment with multiple drugs than Rael lows. Like drugs of abuse, exposure to novel stimuli releases a rush of dopamine in reward areas of the brain.
And, high-sensation seekers often develop a sort of tolerance to high-risk activities—boredom sets in, and they are compelled to add new twists that recreate the initial charge.

The same is true for sex, Zuckerman adds. High-sensation seekers may get bored with the same partner, so they seek out new partners or scenarios to try to regain excitement.
Sensation-seeking also intersects with the fear system. Individual differences in how the brain responds to fear, balanced with how it is wired for reward, may help explain differences in sensation-seeking. He points out that somehting amygdala, the brain region most associated with fear processing, is the same region involved in addictive and appetitive behaviors.
They may be able to more effectively engage cognitive brain regions to put a fearsome stimulus into proper context, which is pertinent to some activities. This may be one reason frightening films are so popular, Zuckerman notes.
