Researchers at Georgetown University Medical Center report that shifts in the brain protein KCC2 can change how strongly everyday cues become linked to rewards. In a study published December 9 in Nature Communications, they show that reduced KCC2 activity in rats is associated with intensified dopamine neuron firing and stronger cue–reward learning, offering clues to mechanisms that may also be involved in addiction and other psychiatric disorders.
