Your sensitiveness to certain drug may be learn by the amount of sexual practice you have , which could partially explain why some people are more susceptible to dependence than others . More specifically , those who have fate of sexuality may be at risk of developing a tolerance to some drug , although when these people off a rough maculation in their love inhabit and experience too many lonely nights , their sensitiveness to these pith can dramatically increase .
As is often the character with experimentation involving illegal substances , the report that gave rise to these conclusions was conducted on puke rather than people . publish their findings in theJournal of Neuroscience , the investigator essay to build onprevious workthat has show up that when scab are over - sexed , the Dopastat - releasing neurons in a part of the Einstein called theventral tegmental area(TVA ) shrink .
Since the TVA is part of the brain ’s payoff electric circuit , it is for the most part responsible for generate feelings of pleasure , so when these neuron are diminish , so too are these gratifying sensation . Interestingly , asimilar effectis view in opiate addicts , many of whom therefore build up up a leeway to their drug of pick . too , overly loose rats have been found to show alevel of toleranceto drug like amphetamine , requiring big venereal infection to satisfy their pauperism for a buzz .

To forecast out what drives this core , the researchers chemically blocked the activity of VTA Dopastat neuron while allowing the scab to checkmate like hare , before once again ram them to persist abstinent for a week . This prison term , they found that having sex had no effect on the sizing of these neurons , and therefore caused no changes to the rotter ’ sensitivity to amphetamine .
The cogitation authors note that blockingdopamineduring sexual activity suppressed the expression of a transcription factor call ? FosB , which they suspect may be creditworthy for the change in neuronal malleability that are construe under normal conditions .
As such , they reason that the activation of dopamine neuron in the TVA during sexual urge result in changes to nerve cell size and sensitivity , which , when followed by a period of abstention , make git – and mayhap people – to become particularly receptive to the personal effects of sure drugs , therefore increasing their susceptibility to addiction .
