Using a prebiotic to influence bacterial activity in the gut after a traumatic brain injury may help reduce impulsive behavior, one of the common symptoms to follow a moderate blow to the head, a new study in rats suggests. Researchers found that adding the prebiotic galacto-oligosaccharide (GOS) to rat diets before and after a TBI lowered their impulsivity in a decision-making gambling test in which they are rewarded with sweets.

New research is uncovering how medications targeting the glucagon-like peptide-1 (GLP-1) system affect brain circuits involved in nausea, thirst, and pleasurable behaviors. These findings will be presented at Neuroscience 2025, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health.
