"We can also see how brain activity changes as people recover from their addictions," said Joshua Brown, assistant professor in the Department of Psychological and Brain Sciences at Indiana University Bloomington, part of the College of Arts and Sciences.
The chronic occurrence of relapse underscores the need for improved methods of treatment and relapse prevention. One potential cause for relapse is deficient self-regulatory control over behavior and decision-making. Specifically this lack of self-regulatory ability in substance dependent individuals has been associated with dysfunction of a mesolimbic-frontal brain network. Reduced activity within this self-regulatory brain network has previously been implicated in relapse, but the specific relationship between this network, self-regulatory ability and recovery is yet to be determined.
The current study explores neurophysiological and cognitive indicators of self-regulatory ability in a community-based sample of substance dependent individuals during the first three months of addiction treatment. The study tests participants' risk-taking inclinations through what is called a Balloon Analog Risk Task, a game in which the participants can decide whether to add increasing amounts of air to a balloon, gaining rewards until it pops. Those who took greater risks were shown to have reduced brain activity. By the same token, those who took less risk showed greater brain activity. By three months those who were successful in treatment also demonstrated a pattern of brain activation that coincided with the risk level of cues during the balloon risk task decision-making. In individuals who relapsed, risk-related activation was limited to certain brain regions, possibly signaling the anticipated reward rather than the risk of negative outcome.
The study, "Neural predictors and indicators of successful early recovery in substance dependent individuals," will be discussed from 11 a.m. to noon on Sunday in Hall F-J. Co-authors are S.E. Forster; and Peter R. Finn, also of the Department of Psychological and Brain Sciences.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
