Recent studies have revealed diverse neuron types in the superior colliculus (SC), a midbrain structure critical for sensorimotor transformation. Here, as an important step toward studying function of these subtypes, we characterize 10 transgenic mouse lines based on recently published molecular atlas superficial SC. We show that Cre or fluorescence expression some corresponds specifically to certain transcriptomic types. These include two GENSAT been used target morphological cell SC and three knockin lines. In contrast, such correspondence is not seen other tested mice. Importantly, pattern marker genes all highly consistent with atlas. Together, our support correlation between types, identify useful targeting genetically, demonstrate validity single-cell transcriptomics data.

Detecting visual features in the environment is crucial for animals' survival. The superior colliculus (SC) implicated motion detection and processing, whereas how SC integrates inputs from two eyes remains unclear. Using vivo electrophysiology, we show that mouse contains many binocular neurons display robust ocular dominance (OD) plasticity a critical period during early development, which similar to, but not dependent on, primary cortex. NR2A- NR2B-containing N-methyl-D-aspartate (NMDA) receptors play an essential role regulation of plasticity. Blocking NMDA can largely prevent impairment predatory hunting caused by monocular deprivation, indicating maintaining binocularity required efficient behavior. Together, our studies reveal existence function OD SC, broadens understanding development subcortical circuitry relating to hunting.

Behavioral flexibility requires directing feedforward sensory information to appropriate targets. In the superior colliculus, divergent outputs orchestrate different responses visual threats, but circuit organization enabling flexible routing of remains unknown. To determine this structure, we focused on inhibitory projection (Gad2) neurons. Trans-synaptic tracing and neuronal recordings revealed that Gad2 neurons projecting lateral geniculate nucleus (LGN) parabigeminal (PBG) form two separate populations, each receiving a set non-retinal inputs. Inhibiting LGN- or PBG-projecting resulted in opposing effects behavior; increasing freezing escape probability looming, respectively. Optogenetic activation selected inputs cells predictably regulated threat. These data suggest projection-specific sampling brain-wide provides design principle enables be selectively routed produce context-specific behavior.
