A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.
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.
Imaging experiments reveal that some brain regions do not distinguish between actions performed using tools and those performed using the hands, while others represent these two types of action separately.
C. elegans exhibits two distinct behavioural macro-states, active and quiet wakefulness, and protein kinase A regulates switching between these two states.
Detailed analysis of fMRI data shows that sequences of movements are associated with individual patterns of neural activity that become more distinct with training.
Hypothemycin, which inhibits a number of protein kinases, kills the T. brucei parasites that cause sleeping sickness and reveals new therapeutic targets for the disorder.
Experiments with realistic acoustic stimuli have revealed that humans distinguish salient sounds from background noise by integrating frequency and temporal information.
