| Open AccessCingulate microstimulation induces negative decision-making via reduced top-down influence on primate fronto-cingulo-striatal network
The neuronal mechanism of how the prefrontal cortex exerts top-down influence on the cingulo-striatal network during decision-making in depressive states is not fully understood. Here authors showed that negative bias in decision-making can be artificially induced via stimulating such neural network and they observed diminished top-down influences correlating with the depressive state.

| Open AccessDopamine control of social novelty preference is constrained by an interpeduncular-tegmentum circuit
Why animals prefer novel social encounters over familiar ones is unclear. Here, authors find that mesolimbic dopamine encodes novel social interaction bout length; whereas familiar social encounters are shortened by an IPN→LDTg circuit that restricts dopamine to control novelty preference.

The neurobiological mechanisms by which binge alcohol consumption disrupts social and emotional functioning are unknown.

Information-seeking behavior in humans is often viewed as irrational rather than utility maximizing. Here the authors describe data obtained in Spring 2020 showing that participants’ concern about COVID-19 was related not only to their drive to seek information about the virus, but also to their curiosity about other more general topics.
