Recordings from serotonin-producing neurons in the brain reveal that these neurons are highly activated by sudden changes in previously familiar environments, potentially explaining why serotonin is important for learning to adapt to such changes.
Oxytocin was found to significantly improve non-social decision making in a healthy sample, suggesting a domain-general function of the hormone, in contrast to its previously hypothesized social domain specificity.
An analysis of recent literature advances novel hypotheses and suggests new experimental approaches in order to build an integrated understanding of prefrontal neural architecture and behavioral repertoires during development.
Songbirds can use arbitrary visual cues to immediately, flexibly and adaptively control syntax of learned song vocalizations in a manner that parallels human cognitive control over syllable sequencing in speech.
A fast spiking interneuron sub-type in medial and lateral prefrontal cortex fires and gamma-synchronizes prominently during adaptive learning of reward values when outcomes are uncertain and choice options have similar values.
