Striatal dopamine 2/3 receptor (D2/3R) availability is related to working memory-induced functional connectivity changes in the default mode network, and this mediates the relationship between D2/3Rs and task performance.

An internet-based cohort study of paired associate learning shows that a first-degree family history of dementia is associated with lowered performance, an effect modified by apolipoprotein E genotype and diabetes.
Maternally experienced environmental stress leads to multigenerational inheritance of ethanol preference and an altered rewards pathway in Drosophila melanogaster.

Single episodes of voluntary exercise induced a functional increase in hippocampal synapses mediated by activity-dependent expression of the BAR protein Mtss1L, acting as a novel early effector of synapse formation.
In multi-channel sensory systems, gain adaptation can help maintain not only coding capacity across changes in signal intensity, but also combinatorial representations of odor identity.
A series of genetically-encoded fluorescent reporters that allow imaging of neuropeptide release in vivo, with sub-second temporal and nerve terminal-level spatial resolution are developed.

Choice history signals bias the interpretation of current sensory input, akin to shifting endogenous attention toward (or away from) the previously selected interpretation.
Genes implicated in the control of mammalian puberty function as components of a molecular clock that determines the timing of sexual differentiation in the C. elegans nervous system.
