A research on “craving” or the intense desire for tobacco establishes the bases for addiction control

21.05.2008
A research team from the University of Granada has carried out a study on the psychological process that triggers the “craving” or intense desire for tobacco, a study that could establish the bases to determine the brain mechanisms that activate this state and how to control them.

Miguel Ángel Muñoz García, from the Department of Personality, Evaluation and Psychological Treatment of the University of Granada has carried out this study, under the direction of the Professors Jaime Vila Castelar and Mª Carmen Fernández Santaella.

”Craving" is an expression used to define an uncontrollable desire for the administration or consumption of an addictive substance. It is usually used in situations of alcohol or nicotine dependence and it is considered as a pathology that affects cognitive resources, as it has an obsessive component.

180 cocaine users

The researchers of the University of Granada analysed, with the help of a device, 180 regular takers of an addictive substance (cocaine, in this case), to study the emotional mechanisms triggering the addiction for the substance. This study has helped to establish the behavioural mechanisms in cocaine addiction, and consists of the emotional control of different consumption situations.

These results have been the basis of a series of studies with smokers, in withdrawal for 8 hours, to measure the physiological and emotional variables present in withdrawal symptoms using a machine (a polygraph) to estimate the emotional mechanisms responsible for the addiction to that substance. The smokers were shown several images (48) connected with situations that produce desire (related with leisure, free time, coffee…), analysing the heart´s defensive cardiac response produced as well as the startle response.

Lastly, brain modifications associated with emotional responses of frustration and impulsiveness in smokers in withdrawal were studied. This system was also used for regular smokers.

Miguel Ángel Muñoz García states that this research has studied for the first time behavioural mechanisms involved in the tobacco craving process determining the brain areas and body responses connected with the compulsive behaviour provoked by tobacco.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
