Title
Diverse neural activity in the mouse superior colliculus
Abstract
The mouse superior colliculus receives retinal input from most retinal ganglion cells and translates visual signals into visually guided innate behaviors such as hunting, escape, and orientation. To understand how these unique functions are implemented in the neural circuits of the superior colliculus, my laboratory studies the diversity of neural activity in response to different light stimuli and behavioral conditions. To do so, we combine in vivo two-photon imaging from head-fixed mice, miniscope imaging from freely moving mice, genetic labeling of cell types, and transsynaptic viral tracking. Today, I will discuss our latest findings on 1) how many functional cell types exist (Schwartz et al., bioRxiv 2023) and 2) how neurons respond to self-motion in the mouse superior colliculus.
