A neural network model of the hippocampus exhibits a division of labor across its two main pathways during category learning, with one pathway specializing in extracting systematic category information and another in encoding arbitrary details.

Hilar mossy cells control seizure-dependent dentate neurogenesis and stem cell quiescence by activity-dependent control of Sonic hedgehog production and signaling.
When the acquisition of reward becomes effortful, marmosets choose to work longer, delaying their harvest, but slow their movements, reducing energy consumption.
Anterior Cingulate Cortex displays robust tracking during strategy execution of a summary statistic for that strategy in recent behavioral history, suggesting a role for this brain region in estimating which actions promote the occurrence of events in the environment.

Correlated light and electron microscopy of cortical neurons reveals a local organization of mitochondria near dendritic spines with diverse functional properties.
Live imaging and taste behavior analyses show that related members of the Gr28 gene subfamily are expressed in largely non-overlapping sets of neurons and mediate opposing taste behaviors.
Prior expectations about the state of the sensory environment are dynamically updated in a context-dependent manner and selectively bias the build-up of human motor cortical activity during subsequent decisions.

A novel FRET approach suggests that the intracellular termini of acid-sensing ion channel 1a do not form a complex at rest requiring a new hypothesis for ASIC1a involvement in stroke.
