Information Sampling

Neural activity in anterior cingulate cortex and the anterior striatum predicts which visual objects are sampled and how likely objects are paired with positive or aversive outcomes. We causally tested whether these neural signals contribute to behavioral flexibility. Disrupting with transcranial ultrasound the ACC, but not striatum, prolonged information sampling when attentional demands were high, impaired flexible learning, and reduced the ability to avoid losses. These results support a role of the ACC in guiding attention and information sampling to overcome motivational conflict during adaptive behaviors.

Lever Pressing

We studied the brain mechanisms underlying action selection in a social dilemma setting in which individuals’ effortful gains are unfairly distributed among group members. A stable “worker–parasite” relationship developed when three individually operant-conditioned rats were placed together in a Skinner box equipped with response lever and food dispenser on opposite sides. Specifically, one rat, the “worker,” engaged in lever-pressing while the other two “parasitic” rats profited from the worker’s effort by crowding the feeder in anticipation of food. Anatomically, c-Fos expression in the anterior cingulate cortex (ACC) was significantly higher in worker rats than in parasite rats. Functionally, ACC inactivation suppressed the worker’s lever-press behavior drastically under social, but only mildly under individual, settings. Transcriptionally, GABAA receptor– and potassium channel–related messenger RNA expressions were reliably lower in the worker’s, relative to parasite’s, ACC. These findings indicate the requirement of ACC activation for the expression of exploitable, effortful behavior, which could be mediated by molecular pathways involving GABAA receptor/potassium channel proteins.
