| Open AccessInformation-based TMS to mid-lateral prefrontal cortex disrupts action goals during emotional processing
The lateral prefrontal cortex (LPFC) is thought to maintain goal-relevant representations that promote cognitive control, but causal evidence has been limited. By targeting action-goal representations in LPFC with transcranial magnetic stimulation and fMRI, the authors found that LPFC promotes goal oriented behaviour during emotional processing.

| 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 AccessSocial buffering in rats reduces fear by oxytocin triggering sustained changes in central amygdala neuronal activity
After rats were trained to fear a sound, they showed less fear when another rat was nearby and this calming effect lasted when the other rat was removed. Both reductions required oxytocin signaling from the hypothalamus to the central amygdala.

| Open AccessThe amygdala is not necessary for the familiarity aspect of recognition memory
It has been proposed that the amygdala is required for the familiarity aspect of item recognition. By studying the performance of monkeys with selective amygdala lesions on four converging memory paradigms, the authors demonstrate that the amygdala is not necessary for familiarity memory, but confirm its role in reward processing.
