The paper uses high-density extracellular recordings to classify neurons by brain region and identify dendritic backpropagation through waveform analysis.

The paper identifies three subregions in the mouse lateral posterior nucleus that form corticothalamic loops biased towards ventral or dorsal visual streams and reveal distinct input sources driving their activity.

The paper develops a biophysically detailed in silico model of layer 4 of the mouse primary visual cortex, showing how functional synaptic connectivity reproduces experimental observations of neuronal responses to visual stimuli.

The paper shows that the first spikes in visual cortex are sufficient for perceptual discrimination in mice, with a threshold duration of 40-80 milliseconds.

The paper investigates how mice perceive hue and wavelength-specific luminance contrast across visual space, finding non-uniform sensitivity patterns.

The paper reports aberrant cortical activity and fluorescence events in some GCaMP6-expressing transgenic mice, suggesting potential artifacts in neuronal recordings.
