Description
High sugar diet contributes to the development of obesity. Recent research suggests that the brain responds to sugar overconsumption similar to drugs of abuse. It is unknown how sugar overconsumption impacts serotonin and dopamine which are critical to the brain’s reward system. This thesis characterises an animal model of sugar overconsumption to examine the relationship between dopamine/serotonin signalling and sugar intake. Our results suggest that sugar dependence negatively influences emotional behaviour and impulse control, dopamine/serotonin signalling and production of new neurons. Understanding how sugar affects the brain will allow the development of drugs to reduce sugar intake and obesity.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
