Topic: whisker-circuits

Animals swiftly react to environmental stimuli, with the involvement of the superior colliculus (SC). While the SC is playing a pivotal role in coordinating innate behaviors such as coordinating orientation and defense responses, its involvement in the somatosensory system remains relatively unexplored. Our recent research has unveiled the connectivity between mouse whisker-circuits and the SC, including pathways from the motor cortex (MC), barrel field of S1 (BC), and brainstem (Bs). Mapping the whisker-sensitive region of the SC in mice revealed a novel trans-collicular connectivity motif, w
