Structural and functional studies of a potassium ion channel that is opened and closed by different ligands have revealed a novel gating mechanism.

Neurons in the hippocampus modulate the rates at which they fire, and the locations in which they fire, so as to encode the information that is central to forming memories about personal experiences.

By using different groups of cells to represent distinct environments and events, the dentate gyrus of the hippocampus helps to keep memories of similar events separate.

Detailed analysis of fMRI data shows that sequences of movements are associated with individual patterns of neural activity that become more distinct with training.

Mechanisms that enable wild mice to survive infection with strains of the Toxoplasma gondii parasite virulent enough to kill laboratory mice offer an explanation for how these parasites have been able to persist in the mouse population.

Computer simulations of interaural time difference decoders show that heterogeneous tuning of binaural neurons leads to accurate sound localization in natural environments.

The major evolutionary routes to drug resistance in Salmonella Typhi are associated with fitness benefits, not fitness costs, implying that prudent antimicrobial use will have no effect as a public health intervention in controlling typhoid fever.

Rats show socially selective helping behavior based on familiarity with the type of rat, but not necessarily the individual rat.

In the Drosophila larval epidermis both the cell identity and polarity of individual cells change as a result of cell rearrangements.

An area of visual-motor cortex called the lateral intraparietal area encodes eye position signals that support visually-guided behaviors and image stabilization.
