This paper introduces SLAP2, a high-speed microscope for measuring submicron synapses and dendritic voltage in behaving mice, revealing nonlinear input-output amplification in neurons.

This study examines neural responses in mouse visual cortex to natural and artificial visual stimuli, finding increased activity in response to natural mismatches but no change in dendritic-somatic coupling.

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.

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.

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.
