We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Biological Relationships to Alcohol Induced Aggression @ University of Texas Hlth Sci Ctr Houston
DESCRIPTION (provided by applicant): This predoctoral training-grant is designed to study how serotonin (5HT) precursor availability relates to measures of impulsivity and alcohol-induced aggressive behavior. Two groups of 50 women each, those with and without histories of physical fighting, will first participate in an alcohol challenge during laboratory-measured aggression. Following the challenge across aggression testing, the same women will be tested with two types of impulsivity paradigms: rapid-decision (IMT/DMT and GoStop) and reward-directed (SKIP and Two Choice) impulsivity tasks. The availability of the 5HT precursor will be measured by the ratio of tryptophan (Trp) to tyrosine, phenylalanine, valine, leucine, and isoleucine, 5 large neutral amino acids that compete with Trp for transport across the blood-brain barrier. The 5HT precursor availability will then be related to impulsivity testing and to alcohol-induced aggression. The goals are to determine whether 5HT precursor availability is related to: (1) individual differences in sensitivity to alcohol-induced aggression; (2) laboratory-measured impulsivity; and (3) physical violence demonstrated before age 15 (Fight+ and Fight). This study will lead to a better understanding of factors that contribute to individual differences observed after alcohol consumption. This project is dependent on a multidisciplinary approach and will provide training in clinical techniques, experimental design, behavioral laboratory testing, neurobiology, analytical neurochemistry, statistical analysis, arid presentation and publication preparation.
