What’s that smell? The advantage of sniffing


Rhythmic sniffing boosts phase-coded neuronal signals in the mouse olfactory bulb that allow odors to be identified.

Microcolumns: elementary neuronal units that carpet the (mouse) brain


A hexagonal lattice organizes major cell types in the cerebral cortex, with similar cells synchronizing their activity in microcolumns.

The free-energy principle explains neural network behavior


Scientists show that the free-energy principle can explain how neural networks work.

Low-protein diet changes sperm and health of future offspring


Low-protein diets in male mice alter sperm and result in offspring that have metabolic problems like diabetes in adulthood.

Memory retrieval needs a neuronal connecting flight


Scientists use optogenetics to discover a part of the brain necessary for retrieving memories of personal experiences.
