It is now evident that various behaviors, which are repeatedly reinforcing the reward, motivation and memory circuitry are all part of the disease of addiction [ 2345678910 ].

Dynorphin, in turn, decreases the dopaminergic function of the reward system, resulting in a decrease of the reward threshold and an increase in tolerance [ 4345 ]. The mesolimbic dopamine pathway connects with three other key regions to form a collection of integrated circuits commonly called the reward system: Commonly called the reward center, the NAcc is heavily connected with pleasure, reinforcement learning, reward seeking, and impulsivity.

It recruits our natural reward system, but potentially activates it at higher levels than the levels of activation our ancestors typically encountered as our brains evolved, making it liable to switch into an addictive mode [ 27 ]. The reference management tool Zotero was used to build a database of all articles considered.

Internet Addiction As this is another emerging topic, there was no time-scope set for this topic, although facebook sexting tamil was given to studies and reviews published in the previous five years.

This inclusive approach facebook sexting tamil been proposed multiple facebook sexting tamil, both historically [ 17 ] and recently [ 1920 ]. This also matches Griffiths proposed differentiation between addictions to the Internet and addictions on the Internet [ 16 ].

Neurobiology of Addiction The scope of this topic was limited to the previous ten years, with primary focus given to articles published in the past five years. Naturally occurring behaviors such as eating and sex, have evolved such that they activate the reward facebook sexting tamil due to the fact that they reinforce behaviors necessary for survival [ 20 ].

Evolutionary Psychologist Dierdre Barrett took up this concept in her recent book Supernormal Stimuli: Thus we believe that it makes sense to limit this review primarily to the studies that meet the most rigorous requirements, studies that address the neurobiochemical and neurophysiological processes known to underlie addiction generally.

We hope that the articles reviewed here will make it clear that the dozens of studies supporting IA and each of its subtypes as being neuroscientifically similar to substance addiction and will demonstrate that all of the possible Internet behaviors must be considered as potentially addictive in the same way, as variations on a theme rather than separate disorders, just as diverse forms of gambling e.

Additional screening was required to differentiate articles about IP included and non-IP not included. In fact it is the case that most IA studies around the world have considered the various Internet behaviors in this light.

This results in acute positive reinforcement of the behavior that initiated the flood. Similarly, Tinbergen created artificial butterflies with larger and more colorful wings, and male butterflies repeatedly tried to mate with these artificial butterflies in lieu of actual female butterflies.

Introduction A revolutionary paradigm shift is occurring in the field of addiction that has great implications for assessment and treatment. The amygdala positive and negative emotions, emotional memoryhippocampus processing and retrieval of long term memoriesand the frontal cortex coordinates and determines behavior.

Method To conduct the research, an extensive literature search and review was performed utilizing a variety of sources: In short, generalized internet chronic overuse is highly stimulating.

We will then review the existing neuroscientific studies relating to the behavioral aspects of addiction generally, then the more specific problem of Gambling Disorder, and then progress to the flood of recent studies on IA, and its subtypes of gaming and pornography.

Other Internet related behaviors, e. Excessive use of the Internet not involving playing of online games e.

Continuous rechecks of the more rapidly emerging subject areas e. Many recognize that several behaviors potentially affecting the reward circuitry in human brains lead to a loss of control and other symptoms of addiction in at least some individuals.

Special attention to nomenclature was required here, as the disorder is studied under different headings. Internet Pornography Addiction Research into the area of addictive sexual behaviors on the Internet began with an inquiry into the various constructs surrounding compulsive sexual behavior.

A universal inclusion criterion was publication in a peer-reviewed journal. Multiple combinations of the following search terms and their derivatives were used in conducting the research: Different classes of drugs activate the reward system through different means, however, the universal result is a flood of dopamine in the NAcc reward center.

This would have aligned the DSM-5 with what has, in fact, occurred in the field since its publication, namely, the continued scientific investigation into the broad range of potentially problematic behaviors involving Internet use.

Together with studies on Internet addiction and Internet Gaming Disorder we see strong evidence for considering addictive Internet behaviors as behavioral addiction. Indeed, the original formal proposal for IA to be included in the DSM-5 incorporated the subtypes of instant messaging, pornography use, and video games [ 17 ], expanded later to include social networking [ 18 ].

There was no specific time-delimitation for this search, however, as with behavioral addiction, analytical priority was placed upon literature reviews and articles published via a newest to oldest methodology.

The American Psychiatric Association APA has recognized one such Internet related behavior, Internet gaming, as a potential addictive disorder warranting further study, in the revision of their Diagnostic and Statistical Manual.Author Contributions.
