`Silent' mitral cells emerge from common feature subtraction

The paper explains 'silent' mitral cells in the olfactory bulb using a computational model that incorporates common feature subtraction, showing baseline activity cancels common olfactory features to enhance odor response.

A spatial code governs olfactory receptor choice and aligns sensory maps in the nose and brain

The paper shows that olfactory receptor expression in the nose follows a spatial code controlled by a retinoic acid gradient, aligning epithelial and brain maps.

Decomposing representational drift across wake and sleep

This study decomposes representational drift in mice olfactory cortex during wake and sleep, showing distinct transformations driven by each state.
