The paper shows that moving visual stimuli elicit topographic and directional responses in most entorhinal neurons, revealing visual input's role in shaping their activity.

The paper maps gene expression and axonal projections of neurons in the mouse primary visual cortex to reveal how retinotopy and cell-type-specific collateralization organize visual-stream output.

This study shows psilocybin disrupts visual change detection by altering cortical dynamics, particularly in SST interneurons, leading to increased surprise signals.

The paper uses single-cell projection mapping in mice and marmosets to show that thalamocortical projections are spatially segregated in marmosets but follow a conserved gradient in both species.

The paper presents a database of spiking activity in the mouse visual system during an image change detection task, revealing task-specific coding patterns across brain regions.

The paper develops a cross-species enhancer-AAV toolkit for targeting specific cell types in the basal ganglia across species, validated in mouse and macaque.

The paper identifies a sparse set of neurons in the mouse visual cortex that mediate illusory contour inference through recurrent pattern completion.

The paper presents an enhancer AAV toolbox for targeting and perturbing striatal cell types and circuits in mice, with validated specificity and cross-species applicability.

The paper challenges the conventional view of mouse higher visual cortex by proposing a unified-V2 hypothesis and presents a dataset for testing alternative models.

This study challenges hierarchical predictive coding models by showing that prediction error responses in visual cortex do not involve feedforward processing and that predictive suppression is not mediated by inhibitory interneurons.

SHIELD enables large-scale electrophysiological recordings in mice by providing a skull-shaped implant for repeated multi-probe insertions across brain regions.

This study maps the cell-type-specific afferent and efferent projections of the mouse claustrum using viral tracing and single-neuron reconstruction, revealing its widespread connections and regional specificity.

The paper introduces a light-inducible recombinase system for targeted genomic modifications in neurons, enabling precise labeling and functional analysis of neural circuits in live mouse brains.
