The paper shows that deleting newly formed dendritic spines after learning disrupts memory formation, but not existing memories or new learning.

The paper identifies topographic organization in locus coeruleus norepinephrine neurons, linking their morphology, gene expression, and activity to specific brain regions and learning-related behaviors.

The paper develops two variants of a glutamate indicator with enhanced sensitivity and tailored deactivation rates for studying synaptic transmission in vivo.

The paper demonstrates that amygdala intercalated clusters encode positive and negative valence oppositely, supporting the opponent-process theory of motivation.

The paper develops AAV-based genetic tools to specifically target astrocytes and oligodendrocytes across species, revealing functional roles in reward-dependent acetylcholine responses.

This study shows that spontaneous network activity during a critical period is necessary for callosal axon projections in the mouse visual cortex, but not fully synchronous activity.

The paper identifies distinct response properties and local subnetworks in callosal projection neurons in mouse visual cortex, showing their connectivity and functional biases.
