For example, studies have reported that nicotine counteracts the decline in the efficiency of certain visual tasks and the slowed reaction time induced by alcohol. Alternatively, using pure nicotine and alcoholic beverages in concert may serve to increase the feeling of pleasure connected with either drug alone. Both drugs have already been shown to boost mind concentrations of dopamine – – a nerve cell messenger implicated in the positive reinforcement underlying addiction. Neurobiological studies have yielded additional conflicting evidence. Some possess reported that ethanol increases the activity of the mind receptors that react to nicotine, while others possess indicated a dampened response of certain subtypes of the so-known as nicotinic receptors in the current presence of ethanol.The problem is the perverse incentive systems in scientific publishing. So long as authors are rewarded for publishing many content and editors are rewarded for publishing them rapidly, new means of gaming the traditional publication versions will be invented more quickly than new control measures could be put in place..
