Abstract Locating the source of a specific sound in complex environment and determining its saliency is critical for survival. The superior colliculus (SC), sensorimotor midbrain structure, plays an important role localization has been shown to have topographic map auditory space range species. In mice, previous studies using broadband white noise stimuli found that neurons use high-frequency monaural spectral cues interaural level differences (ILDs) compute spatially restricted receptive fields (RFs), these RFs are organized topographically along azimuth. However, naturalistic environment, animal encounters may rich components; however, sources can still be localized efficiently. It remains unknown whether how SC respond sounds and, turn, RF. Here, we show results from large-scale vivo physiological recordings response noise, ultrasonic pup calls chirps. We find mouse with distinct temporal patterns spatial preference predominantly at ∼60 degrees contralateral addition, categorized based on their spectrotemporal field demonstrated there least 4 subtypes responsive neurons. Significance Statement (SC) receives visual information used localize objects. While organization composition visually well described, much less known about types properties presented calls, chirp mice while recording Analysis neuronal responses defines classes also stimuli, mainly occur when side but not front animal.

During the past 30 yr, investigating physiology of eating behaviors has generated a truly vast literature. This is fueled in part by dramatic increase obesity and its comorbidities that coincided with an ever increasing sophistication genetically based manipulations. These techniques have produced results remarkable degree cell specificity, particularly at signaling level, played lead role advancing field. However, putting these findings into brain-wide context connects physiological signals neurons to behavior somatic requires thorough consideration neuronal connections: field also seen extraordinary technological revolution. Our goal present comprehensive balanced assessment how associated energy homeostasis interact many brain levels control behaviors.

Abstract The superior colliculus (SC), one of the most well-characterized midbrain sensorimotor structures where visual, auditory, and somatosensory information are integrated to initiate motor commands, is highly conserved across vertebrate evolution. Moreover, cell-type-specific SC neurons integrate afferent signals within local networks generate defined output related innate cognitive behaviors. This review focuses on recent progress in understanding phenotypic diversity amongst their intrinsic circuits long-projection targets. We further describe relevant neural specific cell types relation behavioral outputs functions. systematic delineation organization, types, connections put into context species as these depend upon laminar architecture. we focus circuitry involving saccadic eye movement, Overall, provides insight functioning represents a basis for pathology associated with dysfunction.

Whereas top-down control has been attributed excitatory pathways, existence, connectivity, content inhibitory remain elusive. Here, we combine synaptic two-photon calcium imaging, circuit mapping, cortex-dependent learning, chemogenetics in mice identify GABAergic afferents from subthalamic zona incerta as major source input neocortex.

Abstract The execution of goal-oriented behaviours requires a spatially coherent alignment between sensory and motor maps. current model for sensorimotor transformation in the superior colliculus relies on topographic mapping static spatial receptive fields onto movement endpoints 1–6 . Here, to experimentally assess validity this canonical alignment, we dissected visuo-motor network performed vivo intracellular extracellular recordings across layers, restrained unrestrained conditions, both visual tuning individual premotor neurons. We found that collicular units have poorly defined respond instead kinetic features, revealing existence direct vectorial space vectors, rather than as canonically hypothesized. show neural built according these principles is ideally placed sustain ethological such rapid interception moving targets.

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.
